Inexpensive transmission: Wideband calls are often tariffed differently. In
the United States, wideband calls are about 30 percent less expensive
than narrowband calls.
Simplified billing: Because there is just one call, there is just one record,
making billing and traffic measurements easy.
Reliability: Because the data stream is not split, there are none of the
synchronization problems or individual channel failures that can delay or
disrupt narrowband switching of wideband data.
Faster call setup: Placing a wideband call is faster than placing a
narrowband call because ISDN is used and because there’s only one call
to place, as opposed to several.
Simplified administration: Wideband signaling is administered on the
DEFINITY ECS switch; handling wideband signaling on a narrowband
switch typically requires additional equipment which must be
administered separately.
All of DEFINITY ECS’s networking features have been upgraded to handle wide-
band signaling, notably:
Access endpoints
Administered connections
Mixed mode signaling
Call-by-call service
Auto restoration
World Class Routing
ISDN
These upgrades further simplify the process of combining public and private net-
works and enhance the efficiency of combined networks.
