Broadband Business Access 2
New telecommunications needs for customer networks include higher bandwidth
services based on DS1, DS3, and STS-3c rates; a self-healing capability for
businesses most sensitive to service disruption; and rapid service deployment
and rearrangement to keep pace with a changing environment. The flexible,
advanced capabilities of the DDM-2000 OC-3 and OC-12 Multiplexers create a
powerful platform along with other Lucent 2000 Product Family systems to keep
pace with these dynamic customer needs.
The more a business relies on telecommunications, the more important self-
healing networks become. In particular, finance, medical, transportation,
education, and government users are insisting on a highly reliable network.
These users are also driving for higher bandwidth data and video services.
The large multisite medical facility shown in Figure 2-37 uses broadband services
for intersite imaging and video needs as well as lower bandwidth voice and data
services into the public network based in ISDN primary rate interface (PRI) and
basic rate interface (BRI) interfaces. These services can be delivered efficiently
with the DDM-2000 OC-3, OC-12, and
SLC
-2000 Access System's flexible TSI
and add/drop capabilities. The ring architecture prevents service outage due to a
cable cut or node failure.
