■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 failur es 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 o ne 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.
