The WAN SINGLE card does not have any external connectors on its faceplate.
6.2.2 WAN DUAL Card Description (801020 / 801021)
The WAN DUAL card connects to two T1 or E1 lines, or to one of each type. It works with
only one DSX/CEPT or CSU plug-in module if the WAN port without either module remains
in the standby state.
However, a CGA-Red alarm will be generated for that port.
6.2.2.1 Card Jumper/Switch Settings
The WAN Dual card does not have any jumpers or switches on its motherboard.
6.2.2.2 Card External Connectors and Signal Pinouts

6.2.3 WAN-U Card Description (801120 / 801160)
The WAN-U card is a dual-port card that provides HDSL 2.048 Mbps service when used with
HDSL plug-in modules.
The HDSL module works only on this WAN card, and the
DSX/CEPT and CSU modules do not work on this card.

6.2.4 WAN-R Card Description (801420 / 801460)
The WAN-R card is a dual-T1/E1 card with relays for use in CPU XCON systems with
redundant WAN cards. When placed in slot W4 of a chassis, this card acts as a redundant
(backup) card for up to three standard WAN cards in slots W1, W2, and W3. This arrangement
is known as 1-in-N redundancy, where N is the number of working (primary) WAN cards
supported. If a working WAN card fails, the relay on the WAN-R card in slot W4 will switch
its output to the correct pins on the WAN connector of the associated Interface card in the
system. If the WAN-R card is placed in any other chassis slot, it works like a regular WAN
DUAL card.
