The HWIC-1B-U is a Cisco 1-port ISDN BRI U interface WAN interface card in the HWIC format. It offers one ISDN BRI port with a U interface and an integrated NT1, on a single RJ-49C connector, for ISDN WAN connectivity in modular routers.
On the card, B1 and B2 LEDs indicate ISDN channel status and an NT1 LED indicates connection status. The ISDN chipset is Infineon. The card measures 2.80 x 4.75 x 0.75 in. and weighs 0.45 lbs.
It works in Cisco 1841, 1941, 2800, 2900, 3800 and 3900 Series routers: the 1841, 2801, 2811, 2821, 2851, 3825, 3845, 1941, 2901, 2911, 2921, 2951, 3925 and 3945. The 1841, 2801, 1941 and 2901 take up to 2 of these HWICs, and the other platforms up to 4. Cisco IOS Software 12.4(16) or 12.4(20)T is the minimum on the 1841, 2801, 2811, 2821, 2851, 3825 and 3845, and 15.0(1)M on the 1941, 2901, 2911, 2921, 2951, 3925 and 3945, with IP Base or higher.
The card has the same ISDN BRI features as the earlier WIC: one BRI port, U interface, integrated NT1, as on the WIC-1B-U-V2. Cisco interface cards for branch routers are grouped in Cisco interface cards.
