We have seen very particular problem with WIC- 2T cards. These cards operate properly when G.703 and V.35 modems of 2 Mbps are connected to WIC 2T cards. ( RAD , Attrie ,Ascom ). But when we connected Tellabs 8110 modems ( 2 MBPS ) provided by service provider, protocol flaps up and down and never stabilises. WIC 2T card board version is A0 , B0 and J0. Some times same board versiion works ok and with same board version ( A0 ) it didnt work. Any clocking commands can be given so that protocol will synchronise with modems given by service provider.
Is there any board version problem or any settings are to be done in modems (MLLN type ). The interface configuration is very simple encap is default, bandwidht 2048, and ip address.
Another problem is protocol is up but no ping is successful
Has any one seen such problem with WIC-2T.
Thanks in advance !
