Wideband Switching
Wideband access endpoint
WAEs have no signaling interface to the media server. These endpoints simply transmit and receive
wideband data when the connection is active.
NOTE:
Communication Manager can determine if the connection is active, but this does not
necessarily mean that data is actually coming across the connection.
A WAE is treated as a single endpoint and can support only one call. If all DS0s comprising a wideband
access endpoint are in service, then the wideband access endpoint is considered in service. Otherwise, the
wideband access endpoint is considered out of service. If an in-service wideband access endpoint has no
active calls on its DS0s, it is considered idle. Otherwise, the wideband access endpoint is considered
busy.
Multiple WAEs are separate and distinct within the facility and endpoint applications must be
administered to send and receive the correct data rate over the correct DS0s. An incoming call at the
incorrect data rate is blocked.
Guidelines and examples
This section examines wideband and its components in relation to the following specific customer usage
scenarios:
•
High-speed video conferencing
•
Data backup connection
•
Scheduled batch processing
•
Primary data connectivity
•
Networking
High-speed video conferencing
All data rates are multiples of 64 Kbps; from 128 Kbps to 1,536 Kbps (T1) and 1,984 Kbps (E1) are
supported. Key customer data rates are listed below.

Data backup connection
Using wideband for data transmission backup provides customers with alternate transmission paths for
critical data in the event of primary transmission path failure.
