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 MultiVantage
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.
