WAN Card
6.1 Introduction
This chapter provides installation, configuration, and troubleshooting information for the
Wide-Area Network (WAN) Cards. These include the WAN SINGLE, WAN DUAL, WAN-U
DUAL, WAN-R DUAL and WAN-2P ESF LPBK Cards. These designations are marked on
the faceplate ejectors of the associated cards. Throughout the remainder of this chapter, these
cards are referred to as the WAN SINGLE, WAN DUAL, WAN-U, and WAN-R cards,
respectively.
This chapter also provides similar information for the DSX/CEPT, CSU, and HDSL plug-in
modules used with the WAN cards.
The WAN cards manage the flow of data through the integrated access system network. They
terminate T1 and/or E1 lines and generate or receive network timing clocks. They also
cross-connect DS0 time slots, to pass data through the system from one T1 or E1 line to
another.
The DSX/CEPT and CSU Modules are used to connect to T1 facilities, which operate at 1.544
Mbps. The CEPT function of the DSX/CEPT module is used internationally for connection to
a 2.048 Mbps E1 network. The HDSL module provides an high-speed digital subscriber line
(HDSL) E1 interface.
All WAN cards equipped with CSU or DSX/CEPT modules also act as the "near end"
termination points for the Subscriber Loop Carrier (SLC-96) facilities defined in Bellcore
publication TR-TSY-000008, Issue 2, August 1987.
6.2 WAN Card Descriptions
6.2.1 WAN SINGLE Card Description (800060)
The WAN SINGLE card connects to a single T1 or E1 line. It has one port for a T1 DSX, T1
CSU, or CEPT E1 interface.
6.2.1.1 Card Jumper/Switch Settings
The WAN SINGLE card does not have any jumpers or switches on its motherboard.
