User's Manual

The DECT system components have the following capacities:
• One NTCW00AB DMC8 or one NTCW01AB DMC8-E can support up to 8 basestations.
• One C4600 basestation can support 6 active calls.
• One C4610 basestation can support 12 active calls.
• One C4610E basestation can support 12 active calls.
Multiple DECT systems can co-exist in the same PBX system if they are synchronized to the
same clock source. However, from a user perspective, the DECT systems are separate.
System software parameters
The software that operates the DECT
system resides as firmware in the DMCs. The firmware
consists of an operating program and a system database configuration. The operating program
controls basestation and handset functions. The operating program also communicates with
the system and the DMC DECT Manager. The system data defines hardware and hardware
addressing.
The DMC8/DMC8-E with the ensuing software releases supports the following:
• Release 23 can support basic configuration, CLID and CPND, DECT card addressing
within OA&M, and 16 users on each card.
• Release 24.2x can support up to 32 handsets on each card.
Release 25.xx can support up to 510 handsets with Concentration and MSMN.
The firmware on the DMCs will support CLID, but there is no official way in DECT to tell that
the connected party or CLID has changed. This is a limitation to the DECT standard.
DMC8 engineering guidelines
This section describes the recommended engineering guidelines for the installation of phantom
powered basestations.
The optimum capacity mix of 6-channel and 12-channel basestations is six 6-channel and two
12-channel basestations. Using three or more 12-channel basestations per DMC8 is possible
but is not an ef
ficient use of the 32 channels of the DMC8.
Avaya recommends that the 12-channel basestations be distributed over the DMC8s.
Table 4: DMC8 engineering guidelines for 6-channel RFP (basestation) and 12-channel RFP
(basestation) on page 42 The following table lists engineering guidelines for various
deployments of phantom-powered basestations.
