Multifunctional Interface Card Installation
This
section introduces 1-port ISDN/BRI-U/DTU/IDSL multifunctional interface card(WIC-1DTU).
Multifunctional interface card cable
WIC-1B-DTU/BRI multifunctional interface card supports the following three kinds function mode:
DTU mode:applicable to DDN, supports one 64/128Kbps data channel.
BRI-U mode:applicable to ISDN , supports two 64Kbps B channels and one 16Kbps D channel , use LAPD protocol to realize call/connect/disconnect.
IDSL
mode:applicable
to ISDN Digital Subscribe Line, supplies two independent 64Kbps data channels or
one 128Kbps data channel (by Multilink
PPP )to realize point to point transmit on ISDN.
Note: Multifunctional interface card (WIC-1DTU) can be installed in slot2 of 1750/2620 router and slot1 of 2621/2630/2650 router. More information refers to " Guide for 1750/2620/2621/2630/2650 Router Installation ".
