Full Duplex T1 with a WIC

With a 2621, using a WIC-1T and connecting to a CSU/DSU then to a T1 point to point circuit to another CSU/DSU and a WIC-1T in a 2621. Is the T1 operating at full duplex (that is, 3 meg total) or not?

I see many referances to full duplex in IMA cards and in VPN concentrators but not when it comes to serial connections.

Re: Full Duplex T1 with a WIC

Yes, T1 lines are always "full-duplex". You can run 1.5Mbps in both directions simultaneously, for a potential total of 3Mbps.
