WIC-1T replacement for 4331

[carl_townshend]

Hi All

We currently have a WIC-1T serial interface in our old router with DB60 cable, this is running at 1.544Mbit so I am guessing it is a T1, we want to replace with a 4331, however this interface is not supported.

It is for data only, for this do we need a NIM-1T card?

Many thanks

Carl

Hello,

the NIM-1MFT-T1/E1 is the 'replacement'.

Hi There

This does not have the X21 serial interface though it has the RJ48 type ? we need the X21 connection

Hello,

I don't think you can get the X.21 interface as native, you need a converter such as the one below:
