Hello everyone,
I want to verify I have the correct module. For a 2851 and a 45Mbps DS3 I have a NM-1A-T3 1-port DS3 ATM Network Module. I have been told that I need a different modeul in each 2851. I am told I need a NM-1T3/E3. The info on the circuit from the ISP is Interface: G.703-BNC-75 ohm
Framing Coding: B3ZS/C-Bit
Can anyone verify what module I need?
Thanks in advance. All replies rated

Hello Angel,
an ATM T3 is a different thing then serial DS3.
a NM 1T3/E3 is the right module for a non ATM DS3 connection.
ATM modules may use the same OSI layer1 standard but cannot fallback to behave like simple serial ports (at least in this class of devices)
Hope to help
