This
chapter introduces how to install single ISDN BRI S/T interface card(WIC-1B-S/T).
WIC-1B-S/T interface card , which supports two 64K data channels ,can be used to connect ISDN.
Note: WIC-1B-S/T interface card can be installed in slot2 of 1750/2620 router and in slot1 of 2621/2630/2650 routers. More information refers to the "Guide of 1750/2620/2621/2630/2650 Router Installation".
