Remote digital sets - support and installation?

[pkello]

We have a site which currently consists of:





very large listed house --------------150 meters------------------------server room
NTE (ISDN)
NORSTAR
|
23 Digital sets



The server room and main house are different buildings, connected using 50 pair (150 meters between buildings) and data network. Important note: the main house has existing wiring for digital phones only and a data switch however does not have structured LAN cabling (only cabling is for the digital phones); due to the building is listed/protected status, it is not possible just to install LAN cabling, so it is not possible to replace the digital sets with IP sets.

It was hoped to install an IP Office in the server room (i.e. different location from the norstar), then connect Avaya red digital phones into a DS30 expansion unit, via the existing cabling (including the digital trunking from the building that hosts the server room to the main house (i.e. another building). Plus the NTE would be moved to the server room. Assuming this is < 1000 feet, are towerMAX DS/2 modules required, how many are required for 23 digital sets, does anyone know a UK supplier, what are the implications if we don't use towerMAX DS/2 modules?

What other supported options are available, given that the main building is a listed building, and we cannot just install IP phones?

Thanks in anticipation.

These Application Notes describe the configuration steps required for the Phybridge UniPhyer
LAN appliance to interoperate with Avaya IP Office. In the compliance testing, Phybridge
UniPhyer leveraged the existing single-pair telephony wiring to provide dedicated Ethernet

voice path and Power over Ethernet to Avaya IP Telephones connected to Avaya IP Office.

I would suggest you investigate this product. It may be the best solution for you.
