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?

Actually, 1921 supports HWIC-4T1/E1.
The WIC G703 supports unframed E1, that is usually not necessary.
