I have this T1/E1 card (WIC3-2MFT-T1/E1) installed in a Cisco 3925 router. One of the ports on that card is already programmed as an E1 interface to provide trunk line to the phone company. I need to program the other port on this card as a T1 (ISDN PRI) interface to connect to another device that talks T1 (ISDN PRI). Can that one card do E1 on one port and T1 on the other port?
