Wideband Switching
Issue 5 October 2002 1937555-233-506
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.
Scheduled batch processing. Scheduled batch processing applications are used
for periodic database updates (for example, retail inventory) or distributions (for
example, airline fare schedules). These updates are primarily done after business
hours and are often referred to as nightly file transfers. Wideband meets the high
bandwidth requirements at low cost for scheduled batch processing. In addition,
wideband allows the dedicated-access bandwidth for busy-hour switch traffic to
be used for these applications after business hours; no additional bandwidth costs
are incurred.
