The number of TN2302AP IP Media Processors required is based on the volume of traffic
offered by the active calls on an Avaya R300. The assumption is that one third of the
traffic is carried over the link between the Avaya R300 and the DEFINITY switch, but the
traffic is also based on the percent of calls shuffling. For more information about
shuffling, see ‘‘Shuffling’’ on page 24.
Number of terminals and trunks supported by the
Avaya R300
An individual Avaya R300 supports 26 stations (24 DCP and 2 Analog). For countries
which use 600 ohm impedances, the Avaya R300 also supports two 600 ohm loop-start
CO analog trunks. These two analog trunks support the feature of Emergency Transfer.
This feature enables a relay contact set to directly cut-through the tip and ring of the two
600 ohm analog station ports and to connect them to the two-wire analog trunk interface.
These two analog stations are operating in a loop-start trunk mode (for example, go
off-hook to seize an out-going CO trunk connection). Note that the DCP stations are not
operable in power failure mode. For this feature, the Emergency Transfer relay(s) are
operated either by a loss of power on the Avaya R300 Combo blade or by loss of
registration with the main switch, indicating loss of connectivity back to a main
DEFINITY site. This connectivity loss (could be the main ECS, WAN, LAN) will initiate
an emergency transfer within 60 seconds.
The following are the maximum number of DS0 trunks available:
■ 24 DS0 trunks available per T1 interface with robbed bit signaling (the Avaya
R300 supports a two-T1 model) or 23 with IDSN PRI T1.
■ 30 DS0 trunks per E1 trunk (the Avaya R300 supports a two-E1 model)
■ 2 DS0 trunks in another product model available per BRI trunk (the Avaya R300
supports a six-BRI model).
