E1 Modules for Cisco1921

[ameen.ahmed]

Hi Friends,

I was searching for an E1 card on Cisco1921, however I couldn't find out an exact replacment for HWIC-4T1/E1.

The modules which I came across are, VWIC2-1MFT-T1/E1  and   VWIC2-1MFT-G703

Can anyone please let me know the differences between these two cards VWIC cards ?

Which one should I purchase?

Thanks,

Ameen.

Actually, 1921 supports HWIC-4T1/E1.

The WIC G703 supports unframed E1, that is usually not necessary.
