i have a 2811 (Advance IP services IOS) with 4 Nos of WIC-2T connected to Tellabb 8110 Leased line modem at HO and Cisco 1841 (Advance IP services IOS) with WIC-1T connected to Tellabs 8110 modem.
In the above scenario, there is no communication between HO router and Branch router.
But i insert WIC-1T card on HO router (2811) the communication is happening.
Is there any specific configuration needs to be done in Tellabs 8110 modem to connect Smart serial cable?
I also suspect the issue with WIC-2T cards (on 2811). but i have 4 Nos of WIC-2T, all are giving the same issue.
Can anyone suggest me with the solution?
Thanks in advance....
