operational features of the industry standard
SLC
Series 5 Carrier System and the
SLC
96 Carrier System. The
SLC
-2000 Access System offers better ways of
providing services and supports the standard digital interfaces for universal and
integrated systems. It provides a synchronous optical network (SONET) OC-3
feeder interface, a DSX-1 metallic feeder interface, and enhanced operations,
administration, maintenance, and provisioning (OAM&P) capabilities. The
SLC
-
2000 Access System offers increased system flexibility to serve a wide variety of
network applications.
The
SLC
-2000 Access System is a software-driven DLC system with a built-in
