The
SLC
-2000 Access System builds upon many of the administrative and
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
SONET multiplexer. The system provides up to 768 subscriber lines and 28
subscriber DS1s, and has an option to equip a built-in loop test system test head
[the integral test head (ITH)]. The system supports the following:
■
Basic telephone service
■
A full complement of special services Integrated Services Digital Network
(ISDN)
■
ONUs using both Fiber in the Loop (FITL) and DSX-1 metallic distribution
■
Metallic distribution
■
TR-08 standard interface
■
TR-303 interface.
Basic Description of the DDM-2000
FiberReach Multiplexer
1
The DDM-2000 FiberReach Multiplexer is a full-service access product designed
to support business carrier access, fiber-in-the-loop, and private network
applications. DDM-2000 FiberReach has been designed to serve a multitude of
services through a very modular architecture based on extensive reuse. The
architecture consists of two types of shelves:
■
Wideband Shelf
— Provides the optics for the narrowband shelf, as well as a complete
DS1 to OC-1/OC-3/OC-12 solution. Eight low-speed slots are
available, optionally provisioned for up to sixteen 1x1 protected or
unprotected DS1s, or up to twenty-eight 1x7 protected or
unprotected DS1s. These low-speed slots may also be used to
house T1 extension or HDSL circuit packs. Two function slots are
also available, offering shelf space for 1x1 protected DS3, DS3/OC-
3c data interfaces.
— As part of the 2000 Family of Products, the DDM-2000 FiberReach
Multiplexer supplies complete operations, administration,
maintenance, and provisioning (OAM&P) features with a look and
