Australian Communications Consumer Action Network – National Broadband Network: Guide for Consumers

My comments

After reading this article, I have made a few comments in a manner that isn’t intended to “dig at” the National Broadband Network and its operations but intended to provide level-headed service information about this next-generation broadband service. This may also be similar to other deployments where an FTTH next-generation broadband service is intended as an upgrade over an existing-technology communications service.

The connection will be delivered free of charge while the fibre-optic system is being rolled out in your area and you will receive notice of this from your service provider or NBN Co as it rolls out in your area.

The cabling will be similar to what is used for the current telephony cabling in that area. For most cities, this will be underground fibre-optic cabling, but for outer-urban areas, regional and rural areas, this will be overhead fibre-optic runs on existing telegraph poles.

Tenants and Multi-Tenancy Units

An issue that may arise with rental premises and multi-tenancy units (apartment blocks, shopping centres, office blocks) is that you may have to seek permission from your landlord, body-corporate or building manager to have the fibre-optic wiring done in the building. Your telecommunications / Internet service provider or the National Broadband Network Company will have procedures and forms in place for liaising with these people

Multi-Tenancy Unit / Multi-Dwelling Unit Buildings

The National Broadband Network will be a full “fibre-to-the-premises” deployment with a fibre-optic run to each unit (apartment, house, shop, office space) in the building. Here, the NBN may have to install extra equipment in the building’s wiring closet which may be in the basement or an auxiliary passageway of the building.

Post-changeover

For most people, the telephony and Internet service that you will benefit from will be similar to what you are getting for your current service. There may be revisions to the Internet service concerning download allowances as you benefit from bigger download bandwidths.

Customer Premises Equipment

The device illustrated in the article may be a proof-of-concept article, prototype or pre-production sample that wouldn’t be supplied to customers as part of the NBN rollout. As well, there may be variations in the device’s functionality for the final-issue device. It is also worth knowing that the information that is provided is for the average “Joe Six-pack” who would be running just one classic phone service and one broadband Internet service.

The customer premises equipment will be an “optical network terminator” (ONT) which is a fibre-optic modem that has handset connections for 2 phone services, and four Ethernet ports with 1 port for each Internet service. There is no knowledge of the port speed available through these ports but they may be Gigabit Ethernet ports.

Because there is no power transmitted through the fibre-optic cable, the exchange won’t provide the required power for “lifeline” telephony service. Instead, the power supply that comes with this box will have a backup battery that works in a similar way to an alarm system’s backup battery. Here you will be able to place and receive calls for a certain amount of time when the power goes down.

Of course, this device will be managed by NBN Co and end up being seen by them as a demarcation point for service responsibility.

Customers who have wireless and satellite services will have different CPE requirements but they will have a similar form of connectivity.

Connectivity issues

The home network

Of course, you will have to use an Ethernet-WAN broadband router as your Internet-network edge and there will be the high-end units on the market that will have the Gigabit Ethernet connections on the WAN and LAN Ethernet sockets. For Wi-Fi, these units will need to work with full 802.11n wireless and for HomePlug you would have to use HomePlug AV or HomePlug AV2 setups.

IPTV and IP Telephony

There was nothing mentioned about how one should connect IPTV or IP Telephony equipment; whether via the “edge” router or direct to this ONT box? As well, there wasn’t mention about use of other VoIP hardware like IP telephone to provide the voice telephony service that is normally provided to the telephony ports on this box? This will become more interesting as people consider the use of enhanced IP-telephony technology for their regular telephony services.

Three or more phone services

Similarly, the device doesn’t cater for households with 3 or more classic phone lines such as a business operated from home with the need for a fax service or individuals like elderly relatives residing in the house but wanting the responsibility and dignity of their own phone service under their control. As well, a larger house may be split in to two or more smaller residences and let as such as a way of keeping it viable but may be amalgamated to the larger house for use as a “family house”. Here, there should be support for two or more ONTs in these situations.

This may be rectified through the use of IP telephones that are connected in to the home network and associated with one or more of the phone services; and really shouldn’t be of concern when we move towards full IP telephony.

Modem-to-modem communications

As far as I know, the NBN setup should work with G3 fax, all “human-response dial-out” alarm systems, or most modem-driven monitored-alarm systems connected to the telephony sockets but you will need to check with system provider in the case of your security setup. You may have to scale your fax machine’s throughput to lower “G3” speeds like 14400bps for reliable transmission for reliable operation. I have written further on faxing and monitored alarms in the IP Telephony age in a special article which should be read by customers and industry alike as the National Broadband Network nears.

Small businesses

THe four Ethernet ports may be of benefit to the small-business owner like a cafe operator who wants to run a public wireless hotspot as a separate Internet service. Here, one port can serve a dedicated broadband router like a hotspot gateway for the public Internet service while the other port can serve the business’s “line-of-business” network.

For some other businesses like bars where online vending or amusement machines that are managed by third parties are the order of the day, the separate Ethernet ports can be used to provide an Internet service under the control of the machine’s operator.

Conclusion

This is not simply NBN “spin” but issues that may be of concern whenever an imminent conversion to FTTH technology ins in place for established telecommunications networks.

Telekom startet FTTH-Ausbau für VDSL in Potsdam – VDSL.de (Germany – German language)

My comments

The fat pipe is becoming fatter in Germany

Deutsche Telekom are intending to roll out FTTH (fibre-to-the-home) next-generation broadband into Potsdam, Germany. This is although there is a great penetration of VDSL-driven FTTC (fibre-to-the-curb / fibre-to-the-cabinet) setups in most of Germany, including this capital city of Berlin-Brandenburg.

They intend to have this fibre infrastructure pass at least 21,000 households in the southern and western areas of this city. Building owners will need to give Deutsche Telekom a permit to give the “go-ahead” for the fibre-optic installation work to start in their building, as would be required for most telecommunications works in these buildings; but this could be simply a formality as they realise the benefits of this technology for their tenants.

The deployment pricing will be similar to what has been called for Australia’s National Broadband Network where the installation will be free when the service is rolled out to the area but will cost more for installations commenced after the rollout.

As well, Deutsche Telekom do have a long-term intent to roll out FTTH next-generation broadband to Germany’s major cities.

Moving from FTTC to FTTH

What has interested me about this work is that it is an example of being able to move from an FTTC or FTTN setup with a copper run from a street box to the customer’s door; to an FTTH / FTTP setup which has fibre-optic all the way to the customer’s door. Thi is done while reusing existing fibre-optic cabling infrastructure rather than laying down new infrastructure.

Some of the FTTC or FTTN setups like a few of the deployments occurring in rural Britain are being designed with support for migration to the all-fibre layouts. So anyone who does want to advocate for a part-fibre part-copper setup for a next-generation broadband rollout would need to factor in a future-proof arrangement for FTTH/FTTP all-fibre setups down the track. As well, this approach can cater for environments where some buildings like offices or educational facilities could have an all-fibre rune but as needs change, other buildings could have the all-fibre run. Similarly, it can allow reuse of existing head-end equipment used for the copper deployment like DSLAMs on newer extensions of the part-copper part-fibre setup such as entry to new neighbourhoods for example.

So this setup means that even a part-copper part-fibre setup like an FTTC setup could benefit from higher throughput speeds by moving towards an all-fibre setup while retaining the existing fibre-optic backbone infrastructure.

Customers please note with these conversions

When these networks switch over from a VDSL2-based part-copper part-fibre network to an all-fibre network, you will have to move from a DSL modem router to a broadband router with an Ethernet WAN (Internet) port.

Some high-end modem routers will have a dual-WAN setup which uses an Ethernet port as a secondary WAN port and this may be in the form of a LAN port that can become a WAN port or as a dedicated WAN port. It is worth checking if your modem-router has this setup by referring to its instruction manual or manufacturer’s Website.

Another step towards easily-configurable IP telephony systems has been taken with the UPnP Forum just releasing the UPnP Telephony Device Control Protocol this week. Here, this provides the management of telephone-related devices that are connected across a small network in a heterogenous manner. This involves the ability for the devices to make or take phone calls, be notified of incoming calls, send and receive text and multimedia messages as well as updating local user-presence status.

It is also intended to be service agnostic so as to cater for phone services based on IP-Telephony (VoIP), cellular wireless or classic landline (ISDN or Plain Old Telephony Service) technology; as well as being device form-factor agnostic.

As with the whole of the UPnP ecosystem, this DCP provides increased room for innovation due to a logical “building-block” approach in designing these systems.

Logical Devices

Telephony Client

A UPnP Telephony Client is a device that is used by the end-user to interact with the caller at the other end of the line. A multi-handset phone system would have these devices referred to as an “extension”. This could be a device like a VoIP handset, a “softphone” program run on a computer, a TV or set-top box with IP-based video speakerphone function or a “legacy-handset-bridge” like an analogue telephone adaptor or DECT base station.

The UPnP Telephony system allows different clients to be media-specific, thus allowing for situations like an electronic picture frame that has a Webcam to become a videophone adaptor with the voice part of a videocall placed using this device being hosted through a regular VoIP handset.

Telephony Server

A UPnP Telephony Server device represents anything that can provide a telephone service to the local IP-based network. This can be in the form of a 3G mobile phone connected to the home network via WiFi, a regular telephone that has integrated PSTN/ISDN – IP bridge functionality, but would typically be in the form of a device that works as an “IP-PBX” with VoIP lines and servicing VoIP handsets.

A physical device can have multiple logical “Telephony Server” devices, with one for each “service” that calls come in on. It doesn’t matter whether the calls come in via VoIP or a classic telephony service like a 3G mobile service or the “Plain Old Telephone Service”.  This can cater for the VoIP-enabled router or “IP-PBX” that can handle a few VoIP services as well as a “Plain Old Telephone Service” line; or a mobile phone or “MiFi” router that "front-ends” its 3G/GSM telephony service to the network.

Telephony Control Point

This is effectively the “control surface” for a UPnP Telephony system and can be integrated with a Telephony Client or Telephony Server or be its own device. Typically this would be the buttons and display on a phone but could be a device with its own display or a “widget application” on a computer showing up the incoming call details or incoming text / multimedia messages.

Functionality provided

This device class manages the creation, management and conclusion of a voice or video call between UPnP-compliant telephony “hub” devices and endpoint devices.

The technology allows for a call to be set up using multiple devices on the local side. A good example of this would be to instigate a videocall with the video display appearing on a videophone-enabled TV with integrated Webcam and the conversation sound coming through the cordless handset. Of course, it will do the usual call-management features like call transfer are able to be performed across a UPnP Telephony-based phone setup.

As well, there is support for a common address book that is based on vCard standards as well as the management of answering-machine / voice-mail setups in these systems. Of course, a UPnP-based IP telephone system can support sending and receiving of text or multimedia messages. This would mean that, for example, incoming messages could appear on devices like networked TVs or a Wi-Fi-based cordless IP phone could send messages through VoIP SMS services or “landline-SMS” services provided on PSTN or ISDN services.

Issues that need to be looked at

Establishment of IP-telephony services

An issue that needs to be looked at is the setup and management of IP-based telephony services. Here, this may include the addition of a new service or the establishment and modification of outbound and inbound call-management profiles associated with multiple phone services.

This may involve the use of predefined call classes like “local” or “international” with the ability to determine which service is used for a particular class. Similarly, there could be the use of “default” outbound dialling plans such as “VoIP for all calls except emergency or service calls”. As far as the small-business owner is concerned, this issue may encompass the creation of IP-based “tie lines” between business locations or the creation of “virtual extensions” which are phone numbers dialled as if one is calling an extension within a business phone setup.

The solution that can be used to answer the problem regarding establishment of such services could be in the form of a standard “service manifest” file. This could be an XML file that is prepared by the ITSP (Internet Telephony Service Provider) with all of the parameters associated with an IP telephony service including SIP parameters and default call-management plans for that service. The service’s customer would upload the file to their VoIP gateway through a client-side application or the gateway’s Web interface and simply enable the service.

Inter-extension calling

In the same case, another issue that may need to be looked at is the ability for a UPnP-based telephony system to support the placing of calls between Telephony Client devices, as required of a business phone setup.

This question could be answered through the use of a virtual Telephony Server in a gateway device that represents and handles the internal calls. This could have the internal phone book which is simply a user-friendly list of Telephony Client devices on the system as well as handling that traffic.

Conclusion

Now that the UPnP Telephony DCP has been determined as a standard, it now requires industry to set about the task of implementing it in as many IP-Telephony devices and software programs as possible.

This could be made feasible through this standard being part of one or more logo-compliance programs like how the UPnP AV DCPs have become mandatory for devices that are DLNA-compliant or the UPnP Internet Gateway Device standard has become mandatory for various standards encompassing Internet modems and routers.

It can also open up opportunities of innovation for any device that offers some sort of telephony function while facing a small IP network; or any computer program that works as a bridge to a telephony service like Skype or as a telephony endpoint like a “softphone”.

Smart TVs (A Current Affair article) – NineMSN VIDEO

My Comments

From the recent “A Current Affair” broadcast on the Nine Network, it seems to me that the “Smart TV” or “Internet TV” concept is now ready for prime time.

What is this trend all about?

This is where functionality like access to IPTV channels, “catch-up” TV and video-on-demand is now being integrated in to most of the big-name TV sets that are to be sold at the likes of Harvey Norman. It will also include an “app-store” interface so that users can add functions to these sets in a similar way to how they add functions to a smartphone or tablet computer.

Some of the sets will come with an integrated hard disk which will provide PVR functionality. But what wasn’t mentioned was that most of the sets from the big brands, especially LG, Samsung and Sony, will support integration with the DLNA Home Media Network. This means that these sets could play content held on a computer or network-attached storage device that uses this standards-based technology.

Typically, these functions will be pitched at TVs targeted for the main viewing area i.e. the main lounge room or family room. But this kind of function may be added to existing sets through the use of some of the current-issue Blu-Ray players and network-media adaptors like the Sony SN-M1000P network media adaptor.

A few key questions that I have

“TV plus Apps” or IPTV and interactive-TV content?

There could be a fear that this could turn out as “TV plus apps” with the same old TV content plus some apps such as clients for the popular social networks, photo-sharing sites and YouTube-type sites thrown in.

But some providers are making ties with the various manufacturers to set up free and pay-TV front-ends through the IPTVs. Examples of this include Samsung establishing a tie with BigPond TV to provide direct access to that content or most of the manufacturers running ABC iView through their TV sets. It may also open up opportunities like video-on-demand or boutique content services. As well, once there is a level playing field for adding TV services, this could lead to the addition of extra TV content.

If there is a desire to provide new live or on-demand IPTV services, there needs to be support for adding the newer services to existing IPTV equipment. This could be achieved through an always-live app store on these sets. Similarly, existing broadcast content, both editorial and advertising, must be able to support links to apps and interactive front-ends that are accessible to the average viewer with one click of a particular button through the use of interactive-TV content-delivery standards.

This can include applications ranging from interactive games and competitions that are part of children’s TV through “play-along” quiz shows to polls run in conjunction with current-affairs shows which have the option for you to view “extended-version” interviews.

Equipment Useability

A key issue that I have raised in this site was the useability of services like the Social Web on this class of equipment. Typically, the “smart TV” concept prides itself on connection with social-network services like Twitter and Facebook; but there will be the desire to gain access to photo-sharing sites like Flickr and Picasa or gain full benefit from sites like YouTube. These can make use of “smart-TV” services more daunting for someone who doesn’t find themselves competent or isn’t experienced with technology.

An example of this was when I mentioned to a friend of mine about the Pixel Eyes app on the TiVo platform where they could view their Picasa albums through the lounge-room TV connected to the TiVo PVR. I mentioned that they would have to log in to their Google account using the “pick-pick” method of entering their credentials in order to view their pictures on this service and this idea frightened them off it.

The main problems is that different users will want to log in to this common terminal or, in the case of the Social Web, leave comments in relation to what they are viewing. Typically, this will require a fair bit of text entry and most remote controls won’t be fully engineered to cater to this requirement. The user will typically have to work a D-pad or wave a Wii-style “magic remote” around to pick letters from an onscreen keyboard and may have to switch between logical keyboards to use different character sets like numbers, different-case characters or punctuation. Try entering in a Facebook / Twitter / Google username and password that way or “knocking out” a Tweet that way.  As well, I have raised in that same article methods in which logging in to these services from devices like TVs and set-top boxes can be simplified and referenced how Facebook achieved a login experience suitable for these devices with their HP ePrint app. This includes being able to change the active user associated with a TV or set-top box to another user.

Similarly, I would look at issues like keyboard support for IPTVs. This is whether a TV comes with a QWERTY-enabled remote or not. The best method for add-on keyboard support would be to use Bluetooth HID connectivity so that a Bluetooth-based wireless keyboard can be used as a text-entry tool. Similarly, the ability for one to plug a standard USB computer keyboard in to the USB port usually reserved for USB memory keys and use this for text entry may make things easier. This would work well with those wireless-keyboard sets that plug in to the computer’s USB port.

A remote that doesn’t have a QWERTY keyboard but uses a numeric keypad for direct-channel-selection or parental-code-entry could use this keypad as an “SMS-style” text-entry interface, something which many nimble-fingered teenagers are used to. This would work better if it used the character-set-selection practices used on popular mobile phones.

Other methods that can be looked at include the use of smartphone apps as virtual remote controls like what Samsung has done for their Android smartphones. Here, a user could download an app to their Galaxy S phone and have this become the TV remote control. This could be extended to ideas like multi-control for interactive applications such as “own-account” operation for Social Web and similar applications with the TV screen becoming a “common monitor”.

What to consider when choosing or using your network-enabled TV

DLNA functionality

The TVs or set-top devices should support DLNA Media Player functionality at least, with preferable support for DLNA 1.5 Media Renderer functionality. Initially this would give you access to content held on your computer’s or network-attached-storage device’s hard disk.

The Media Renderer functionality can allow the TV to be controlled by a UPnP AV / DLNA control point such as TwonkyMobile, PlugPlayer or Andromote on your smartphone or tablet computer, or TwonkyManager on your netbook.  In the case of Blu-Ray players and set-top devices, you may even be able to play music from your network storage through your favourite stereo without the need to have the TV on to select the music

If the TV or set-top box offers integrated PVR functionality, look for DLNA Media Server compatibility because this may allow you to play recorded TV shows on other TVs in the house without them needing to be of the same brand.

It is also worth noting that some DLNA functions like DLNA server or Media Renderer may not be enabled by default even though the set has these functions. Here, you may have to go to the setup menus and look for “DLNA control”, “Media Server” or similar options and enable them to benefit fully from these functions.

For further information, it is also worth reading the DLNA Networked Media articles that I have written on this site.

• Getting Started with DLNA Network Media Sharing
• Setting up “PC-less” Networked AV
• The 3-Box DLNA Home Media Network

Connecting the set to your home network

When you connect one of these TVs to your home network, I would suggest that you avoid using Wi-Fi wireless connectivity, especially if the TV or set-top box uses a dongle for this connectivity rather than integrated Wi-Fi connectivity. This is because of the fact the Wi-Fi network is radio-based and if anything is shifted slightly between the Wi-Fi router and the TV, you may have service-reliability issues.

Instead, I would recommend that you use a wired method such as Ethernet cable or a HomePlug AV powerline-network setup. The Ethernet-cable solution would work well if the router and TV are in the same room; you have wired your home for Ethernet or you can get away with snaking Ethernet wiring through windows. On the other hand, the HomePlug solution would work well for most users who don’t want to or can’t lay new wiring through their homes because this uses the house’s existing AC wiring.

In fact, if you are renovating or rewiring your home, it may be worth considering wiring the house for Ethernet and making sure you have an Ethernet connection in the main TV-viewing areas of the house. This may be achievable if you have an electrician who is competent or knows one who is competent with communications or data work doing the job.

Conclusion

This site will have regular coverage of home media network issues that will become of importance as we head down the the path towards online home entertainment.

Toshiba Portege R835-P56X Review – Laptops – CNET Reviews

My Comments

There is now a “race for the best” going on with the 13” “traveller / hotspot-user friendly” class of laptop at the moment thanks to the new Sandy Bridge technology. This is even though the netbook is appealing as a The gauntlet had been laid down by Apple with their latest MacBook Pro laptop for the MacOS X platform and everyone is trying to match this goal in an affordable way.

Examples of the improvements we will see with these computers will be improved video performance as well as an increase in the runtime available for the computer on its own battery. Some of these machines could allow for a hot-footed workday without the need to look for power outlets so you can charge up that laptop.

An example of this is Toshiba’s Portege R835-P56X laptop which uses this technology. The CNET review posted improvements in battery life by 3 hours over the previous model as well as video performance. This battery runtime period that was quoted for the Toshiba when running a video clip was nearly 8 hours, which would cover a typical workday of hotspot-surfing or public-transport working. It also is ready for USB 3.0 and can work with Wi-Fi N wireless networks.

Yet this machine still comes with an integrated DVD burner as well as 4Gb RAM and 640Gb on the hard disk. This capacity may be important when you take those digital pictures and you want to “dump” them to the computer for editing and uploading while on the go. But users may have to check their configuration comes with integrated Bluetooth when they “spec” the unit they want if they do want this function. This would be more important if you do want to pass audio to an amplifier using a Bluetooth A2DP audio module, use your favourite Bluetooth headset to Skype with or use this technology to “tether” your mobile phone to the computer.

At least the new Sandy Bridge technology could allow for this class of laptop computer to improve and become more appealing to those of us who create content while “on the go”.

Sony Unveils its new premium VAIO S Series laptops

My comments about the new trend

Cost-effective system design

Due to the integration of the CPU and the graphics processor in the one chip, we will find that most computer systems will become cheaper to purchase. This will also mean that graphics performance for most multimedia and games activity will start to come at a cheaper price and be available in product classes that wouldn’t otherwise have it like mainstream-priced computers and the subnotebook / ultraportable class of portable computer.

Dual-mode graphics

There will also be an increased use of dual-mode graphics technology as a product differentiator for midrange and high-end machines. This is where a computer is equipped with integrated graphics as well as a discrete graphics chipset and the computer uses integrated graphics for most tasks but uses the discrete graphics for video editing and intense gameplay.

This could be seen like the computer-graphics equivalent of the “overdrive” or “sports mode” switch used on some cars as a way of allowing the car to work in a performance-enhanced way. Here, the user benefits from reduced energy needs and reduced battery consumption when they use the integrated graphics but can use the discrete graphics chipset when they need the extra graphics performance.

Could this change the positioning and pricing of computers?

This may have some some effect on the prices for most of the mainstream computer ranges especially if the equipment in question is to be sold with “single-mode” graphics. Of course, the “dual-mode” graphics will still be pitched at the market who place heavy importance on graphics performance like line-of-profession imaging (CAD/ CAM, graphic arts, medical imaging, etc) and “LAN-party” hardcore gamers and will still command the price premium. Here, the manufacturers can still work on performance-optimised discrete GPUs for this market and offer them in the “dual-mode” computers.

Some people may also reckon that the ability for computers based on these chipsets to perform to mainstream expectations for multimedia and gaming may allow people who value these functions to spend less on the equipment that they want. They can also place importance on “size and style” without sacrificing graphics performance.

It can therefore lead to ultra-compact computer types like 12”-14” subnotebook / ultraportable computers and small-form-factor desktop computers being offered with decent rather than second-rate graphics performance. This could, for example, make the subnotebook more appealing as a “travel workstation” for a photo journalist or other professional photographer to use when editing or previewing photographs and video footage in the field.

How to factor this in when buying a computer through this year

What I would reckon that you should do is determine what class of computer that suits your needs, including your minimum specifications for functionality. This includes hard disk capacity, RAM memory capacity, screen size, user interface, operating-system and other factors. Then look for the good deals where you can save money on the prospective computer purchase.

It may also affect the pricing and positioning of computers based on existing “separate-GPU” graphics technology especially as manufacturers move towards the new combined CPU/GPU technologies. Here, they will be wanting to clear the warehouses of these machines and you may find that the deals are favourable to you with these computers. As I said before, work out your system needs and shop around for the cheapest and best one that will suit these needs. Also take advantage of “deal-makers” that will be offered like applications software, higher-tier operating systems (Windows 7 Professional at Windows 7 Home Premium price), and extra RAM and hard-disk capacity.

Conclusion

Once the new CPU/GPU chipsets become the mainstream for desktop and portable computers, this could bring about a subtle but real change affecting the design, product-positioning and pricing of these devices.

Introduction

I am reviewing the Rotel RCX-1500 network CD receiver which is one of the first “big-set” hi-fi units that I have reviewed that can do proper Internet radio and benefit from the DLNA Home Media Network. Previously I have been reviewing Internet radios that are mainly “small-sets” which are table / clock radios or portables and are intended for use as secondary or auxiliary audio devices.

The product class

This unit is infact a CD receiver, a class of “single-piece multi-function” hi-fi music system which continues from where the music centres and casseivers (receivers with integrated cassette decks) of the 1970s and early 1980s left off. Here, some of these units were equipped with the functionality and quality of modest separate-unit hi-fi systems yet they offered this in a single box, which you could just hook up a pair of speakers to. The manufacture of high-sndard pieces of this class of equpment had diminished through the late 80s. This is although Bang & Olufsen were consistent in this field at a premium price and a few other manufacturers like Proton, Bose and Onkyo were releasing in to their model ranges  one or two receivers with integrated CD, tape or MiniDisc transports that weren’t just second-rate music systems.

Then there had been a slow but sure renaissance in this class of good-quality integrated-function hi-fi equipment as the trend for “downsized” living especially in “executive” city apartments became more intense. This is where most of the good hi-fi names ran with at least one CD receiver in their line-up that didn’t come with a set of substandard speakers and this Rotel RCX-1500 that I am reviewing is one such piece of equipment.

Price

Unit alone: AUD$1999 (recommended retail price)

Speakers (Cabasse Antigua MT30): AUD$999 / pair (recommended retail price)

Functions

Connections

Speakers

This unit was tested with a pair of Cabasse Antigua MT30 bookshelf speakers connected using premium audio cables. These speakers were also on loan from the distributor so I can review this unit properly. They are built using an orthodox two-way driver arrangement and use a bass-reflex enclosure and can work with amplifiers that have a minimum power output of 75 watts and maximum of 500 watts. As far I was concerned, these speakers worked very properly with all kinds of music and could yield a decent sound for their size.

The Rotel CD receiver

Functionality comments

Slot-load CD player

It is also worth knowing that this CD receiver has a pair of pre-out connections so one can connect it to a more powerful and better-sounding power amplifier or a pair of active speakers like an active subwoofer or some of the active speakers like B&O’s Beolab range or any of the Bose Powered Acoustimass speakers.

It can connect to your home network via Wi-Fi or Ethernet using supplied network-adaptor dongles. The Ethernet option can also allow it to be used with a HomePlug AV network segment using an appropriate “homeplug” adaptor and I would recommend this as a “no-new-wires” option for connect this CD receiver to the home network.

This functionality allows this CD receiver to provide Internet radio or work with a DLNA-compliant media server that is on your home network. The only limitation with this function is that it doesn’t work as a MediaRenderer which means that you have to select your network media using the Rotel CD receiver’s display.

The tuner is “up to the minute” with broadcast radio in Europe and Australia by supporting FM RDS as well as DAB+ radio. There are two antenna connections for both FM and DAB but you can choose to use the FM aerial for DAB. It came with two aerials – the typical “T-wire” for FM and a small whip one for DAB. With this one, it was able to pick up Melbourne’s DAB multiplexes reliably as long as it was near a window.

But I would rather that this unit be connected to an outdoor aerial especially for FM reception so it can provide clear signal reception. You may also be able to use a digital-optimised Band III aerial for better DAB+ reception especially on fringe areas.

You can connect an iPod or iPhone to the front USB socket using the data cable supplied with your Apple device and the sound that is played off the iPod will be converted to an analogue form using the Rotel receiver’s internal digital-analogue converter. As well, this same socket is used for playing music held on USB memory keys.

The CD player is a slot-load type that performs as expected for a decent-standard player. It can play the regular CDs or file-based MP3 discs and gives “best-case playback” for any CDs recorded with the HDCD mastering technique. This does yield to high-quality sound from these discs.

As for connection of external equipment, this is feasible with a line-in connection in the form of RCA connectors or SPDIF digital in the form of coaxial or optical connectors. There isn’t a line-out connection that is independent of the volume control for use as a recording connection, which may limit this unit’s utility with cassette or MiniDisc decks.

It is also controllable by a supplied remote control which has a numeric keypad for direct access to 30 presets in each of the radio bands – FM, DAB and Internet. As well, this remote also allows for direct access to tracks on a regular CD and is a preferred control surface when you are searching content on a well-stocked media server or using the CD receiver’s setup menus.

The unit's remote control

This unit’s amplifier is engineered for sound quality. Here, the volume control is a motor-driven potentiometer managed through the control on the front or the remote control. There aren’t any tone-control options, which may please audio purists who believe that tone adjustment affects sound quality.

The display is the white bright fluorescent display but uses four lines of text. This also works with the menu-based operation for advanced functions.

Sound quality

The sound quality for the Rotel RCX-1500 CD receiver is what you would expect for equipment in its class. This is even so with the Cabasse Antigua speakers that I am testing this unit with.

It comes across as being tight and good across all frequencies. This means that it gives all the instruments in a sound recording a proper chance rather than sounding like the old pub jukebox. This has come across so well with well-recorded rock like Peter Gabriel’s “1 – Car” album which was considered to be in the same league as Pink Floyd. Here, you still had that “punchy sound” while hearing the vocals and other instruments.

This system was even performing well with classical music especially as I was playing through a recording of Beethoven’s Violin Concerto which was done with “period” instruments. Here, the combination of this CD receiver and the Cabasse speakers shone through the whole of this popular concerto and was clear with all of the instruments.

As for handling the audio codecs, this amplifier answers the requirement for handling properly-encode music properly especially if you use the “maximum” throughput settings for the codecs like 320kbps MP3 or 192kbps WMA.

Limitations and points of improvement

The network connectivity could be improved on by not requiring the user to deal with easy-to-lose dongles. This is more so with Ethernet as most Internet-enabled hi-fi components and TVs use integrated circuitry with an Ethernet socket on the back.

As well, the Rotel could benefit from WPS setup for Wi-Fi wireless networks especially as most current-issue routers implement this easy-to-use setup method.

An improved version of this unit could support a proper tape loop and a phono input for use with a turntable especially as a lot of the older people may keep records or tapes lying around and could benefit from a simplified system with these inputs.

Conclusion

This is one network-enabled CD receiver that I would recommend for people who have a pair of good-quality bookshelf or “piece-of-furniture” speakers that they wish to keep going but want to benefit from newer sources like music held on their home network or iPod; or Internet radio. I would also consider this unit as a the core of a simplified music system if they want to choose their own good speakers.

This unit, along with the Cabasse Antigua speakers or bookshelf speakers of a similar standard, would be an ideal simple music system for use in an apartment or small house by people who place high value on music. It is especially more suitable with older retired people who are moving towards smaller flats or retirement villages.
