WAN-R Card Description (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. The WAN-R (801460) card works with CSU module (81230).
