As compare to WIC-1DSU-T1


The T1 CSU/DSU WAN Interface Card provides full or fractional T1 service. It does not do channelized T1. Look at this link below for more information.

Yes, it can physically occupy the same slot size (WIC), so it can serve as a replacement in the router. But...


No, you cannot use the WIC-1DSU-56K4 on the same leased line as a WIC-1DSU-T1. You have to replace the leased line circuit too, with one that is compatible with the new WIC.


The T1 leased line circuit uses pins 1, 2, 4, and 5 in an 8-position connector (RJ-45 or RJ-48), when it connects to the DSU/CSU. The 56K leased line uses pins 1, 2, 7, and 8. They don't match up. Signaling on the lines is different, too.


Is this the information you are looking for?
