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.
The following table provides information on Wideband Switching channel types.
Channel Type
Number of Channels (DSOs)
Data Rate
H0 (T1 or E1)
6 (grouped 4 (T1) or 5 (E1) quadrants of
6 B-channels each)
384 Kbps
H11 (T1 or E1)
24 (on T1 - all 24 B-channels, with the
D-channel not used; on E1 - B-channels 1
to 15, and 17 to 25, and B-channels 26 to
31 unused)
1536 Kbps
H12 (E1 only)
30 (B-channels 1 to 15 and 17 to 31)
1920 Kbps
NxDS0 (T1)
2-24
128–1536 Kbps
NxDS0 (E1)
2-31
128–1984 Kbps
