Wideband Switching - Avaya Communication Manager Administrator's Manual

Managing Data Calls
Do not use telephones with data modules with the PC Interface. (You can still use 3270
●
Data Modules if you also use 3270 emulation). If you attach a DCP data module or ISDN
data module to a telephone that is connected to a PC Interface card, the data module is
bypassed (not used). All the interface functions are performed by the interface card even if
a data module is present.
The 7404D telephone with messaging cartridge cannot be used with PC Interface.
●
However, the 7404D with PC cartridge can be used, but only with Group 1 configurations.

Wideband Switching

Wideband Switching provides the ability to dedicate 2 or more ISDN-PRI B-channels or DS0
endpoints for applications that require large bandwidth. It provides high-speed end-to-end
communication between endpoints where dedicated facilities are not economic or appropriate.
ISDN-BRI trunks do not support wideband switching.
Wideband Switching supports:
High-speed video conferencing
●
WAN disaster recovery
●
Scheduled batch processing (for example, nightly file transfers)
●
LAN interconnections and imaging
●
Other applications involving high-speed data transmission, video transmission, or high
●
bandwidth
Detailed description
ISDN-PRI divides a T1 or E1 trunk into 24 (32 for E1) channels, where one channel is used for
signaling, and all others for standard narrowband communication. Certain applications, like
video conferencing, require greater bandwidth. You can combine several narrowband channels
into one wideband channel to accommodate the extra bandwidth requirement. Avaya
Communication Manager serves as a gateway to many types of high-bandwidth traffic. In
addition, DS1 Converter circuit packs are used for wideband switching at DS1 remote EPN
locations. They are compatible with both a 24-channel T1 and 32-channel E1 facility
(transmission equipment). They support circuit-switched wideband connections (NxDS0) and a
192 Kbps packet channel.
