Trade Lead Description:
The Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) WAN interface cards are shared between the Cisco 1600, 1720, 2600 and 3600 Series Routers. Each card supports a single ISDN BRI port offered with and without the NT1 interface.
The S/T WAN interface card module (WIC-1B-S/T) needs the external Network Termination 1 (NT1) device whereas the U WAN interface card module (WIC-1B-U) has an internal NT1 device. The WIC-1B-S/T interface card requires RJ-45 to RJ-45 straight-through cables. Posted from China - Guangdong on 25 October, 2005
