Wideband Switching

Wideband Switching
(Not available with Offer B) 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 connectivity between endpoints where dedicated facilities are not economic or appropriate.
ISDN-BRI trunks do not support wideband switching.
Brief description
ISDN-PRI (and the emulation of it by Asynchronous Transfer Mode-Circuit Emulation Service
(ATM-CES)) divides a T1 or E1 trunk into 24 (31 for E1) information channels and one signaling channel
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. Wideband switching is also supported by the Expansion Interface (EI) circuit
pack and the DS1 Converter circuit pack (for Center Stage Switching or directly connected port
networks) and the ATM-EI circuit pack (for Asynchronous Transfer Mode connected port networks).
ATM-CES supports wideband switching only for access, tie, and tandem trunks, not for line-side
connections.
Wideband Switching supports:
•
High-speed video conferencing
•
WAN disaster recovery
•
Scheduled batch processing (for example, nightly file transfers)
•
LAN interconnections and imaging
•
Other high bandwidth applications involving high-speed data transmission, video transmission,
etc.
