CAB-DSU-RJ45 cable

[ddufault]

I have installed a WIC-1DSU-56K card into a Cisco 1721 router and the card came with a CAB-DSU-RJ45 cable. My telco tells me I require a RJ48S or RJ48C cable to connect to the Frame circuit. I read on a vendor site that the CAB-DSU-RJ45 is equivalent to RJ48S but have been unsuccesul in validating this on Cisco site. Can anyone confirm\refute that the cable I have will work?

That cable and any straight ethernet cable will work.

For 56k/64k's you only need pins 1,2,7 and 8.

For T1's you only need pins 1,2,4 and 5.
