That cisco link does not specify the cable itself, but only the pin outs. True T1 cable has a foil shield around each pair, also called ABAM cable in the telco world.
Ethernet cable is twisted pair without any shielding between pairs. And one shield around all the pairs is not the same as ABAM. Lyle Giese LCR Computer Services, Inc. On 12/08/11 10:53, Carlos Alvarez wrote:
