The most efficient way of working while away from your desk available today.

Large potential call cost saving.

Private Mobile Extension (PME) combines the convenience of using a mobile phone with the cost advantages and features of your fixed line telephone system. When you are out of your office, your mobile operates normally. When you return to your office, your mobile seamlessly connects to your PME system and becomes an extension handset, as well as taking mobile calls as usual.

PME will give you one handset, one number, one network, one bill

Does the PME support PAIRING. The Ability for Desk phone and Mobile phone to share the same extension.ddi number. When DDI is called both devices ring concurrently, which ever device is used to connect the call auto ceases the ringing of the other device

Might be better to ask if hold and transfer is supported Does the PME support DTMF Function.

What Do You Need To Know?

I am in a long term mobile phone contract and want to keep my mobile phone number, what do I need to do? Set up a call divert on your mobile phone Back to Top

What coverage is provided by the BTS access point? 300m omni directional in building Back to Top

How many people can be supported on a single BTS access point 7 concurrent voice calls can be made from a single BTS but you can have many more handsets registered to a single BTS. Back to Top

Why must I order my DSL connection from CommsIQ To ensure voice quality and a professional service and to prevent disruption to the service we will only support PME installations on our approved DSL lines as listed in the price list. Back to Top

- If the mobile has registered to the BTS access point can it receive calls/SMS sent to my regular mobile number To get mobile calls to your PME extension a 'no network coverage' divert would need to be setup to send calls to your device whilst on the PME system. SMS will not be delivered to your device whilst on the PME but are queued and sent when you rejoin the macro network. SMS between the users on the PMN are provided. Future developments to support external SMS are planned. Back to Top

Are call charges incurred? Calls are free for PMN phone to PMN, there is a charge for PMN to external/desk phone if out of service area Back to Top

Do calls between mobiles within the same BTS access point trombone and incur extra call charges. No the voice traffic stays local and doesn't utilse the DSL connection so a call between mobiles on the same BTS access point is a free internal call between extension. Back to Top

What happens when I make a call from inside my private mobile network and leave the area of coverage. Does the call stay up? No - when the handset loses coverage from the local BTS access point the call is dropped, the handset will then select your regular Mobile Network Operator and the call will need to be redialled, assuming the handset is running the Netswitch application.. Back to Top

What happens if I'm already on a call using my regular Mobile Network Operator and enter an area covered by my private mobile network. Does it stay on Vodafone until I hang up or transfer to the private network? The call will remain with the Mobile Network Operator for the duration of the call, when you hang up the handset will then transition onto the private mobile network. Again assuming you are running the Netswitch application on the handset. Back to Top

Are there any phones or networks that have issues or don't work? The best user experience is gained on Symbian Series 60 and Windows Mobile 5,6 and 6.1 handsets as the Netswitch client automatically transitions between the private mobile network and the Mobile Network Operator. Other handsets rely on a manual transition from one to the other, Blackberry devices fall into this category and will not be able to send or receive emails whilst on the private mobile network. Development work is still being undertaken in this area and information will change over time. Back to Top

How many simultaneous calls from one BTS access point? Each access point will support 7 concurrent voice calls, and multiple BTS access points can be configured to accommodate greater call volume. Back to Top

There is mention of battery life being extended - why is this? Battery life is extended because whilst using Low Power GSM the handsets radio is transmitting at 200mW rather than 1W. Back to Top

Are there any safety/health advantages of using Low Power GSM? Low power GSM means that the BTS access point is transmitting at 200mW as opposed to 25W or greater from a regular Mobile Network Operators mast and the handset also transmits 200mW rather than 1W, a typical DECT access point will typically transmit at 250mW. So Low Power GSM can be used in areas where regular GSM isn't allowed. Back to Top

What are the site survey requirements? All installations require a site survey to determine the number of BTS access points that are required to give both sufficient coverage of the area and sufficient call capacity. Back to Top

Is there any impact on voice quality? Voice quality is high as you would expect from any professional solution, the quality within the PME is the equivalent to a mobile network with good coverage and is in many cases an improvement on the voice quality provided by connection to the macro GSM network in building. Back to Top

Does the PME support PAIRING. The Ability for Desk phone and Mobile phone to share the same extension.ddi number. When DDI is called both devices ring concurrently, which ever device is used to connect the call auto ceases the ringing of the other device Currently the PME extension cannot be registered on two devices at once, the user registers on the device they are using at any given time, when used with intelligent Number two alternatives can be set Back to Top

Might be better to ask if hold and transfer is supported Does the PME support DTMF Function. The ability for mobile phone to access feature set of the host PBX via DTMF so that once a call has been answered, the call can be held & transferred around the building from the mobile device whilst the call stays 'on net' on the PBX. Yes handset depended you can hold a call, create a new one and transfer that call onto the new recipient whether that user is another PME handset or a regular desk phone Back to Top

Does the PME have CLI Pass Through. The Ability for the PBX to 'pass through' incoming callers CLI or internal extension as CLI to mobile device. Also the ability to SEND the users DDI number as a CLI when calling via the PBX. Yes the CLI of the incoming call is displayed on the PME handset and yes the CLI of the PME handset is passed when calling other PME and desk phone users. Back to Top

Does the PME support DIAL THROUGH. The ability for mobile device to seamless make calls to other users on the system by dialling their respective extension numbers without the need for any digit insertion prior to the mobile device sending the number. When calling other internally the user would dial the internal extension number the same as would be dialled from a deskphone, the same goes if a PME user wanted to call another PME user the internal number can be used. Back to Top

Does the PME support BREAK OUT. The ability for user to dial 9 and make call via the PBX trunk lines Yes the system can be setup either way if you want your users to actively have to add the 9 to make an external call then that can be done, if you would rather have the platform add the 9 on for your users allowing for them to dial the number from their address book as normal then that can be done too. Back to Top

How does PME coverage compare to DECT? A PME BTS access point will typically cover the same area as 3-5 DECT units depending on DECT manufacturer Back to Top

Is a PSTN Line required? A PSTN line into the building is needed for the DSL installation, the DSL installation used for PME must be provided by TT-Office Back to Top

How is Installation Handled? The IP Telephony connection is provided as a hosted service and no installation is required. The hosted service is delivered over DSL or IP wide area connections. Locally, PMN BTS Access Point units are required. Prior to installation, radio planning determines where the PMN Access Point units are needed to provide coverage in the local area and for the number of users being supported. Our Project Team provides on-going support and advice on the required pre-installation works and assist in the installation of the PMN Access Points. The solution is pre-configured with Ethernet connectivity between the PMN Access Point(s) and the local network connection. On-going administration is possible through the web-based administration tools provided and no specialised skills are required. Back to Top
