Just to clarify I have an Adtran 2800 and a Nortel Secure Router 3120 with a MM-8T1E1 card. It seems as if one of the ethernet cables running from the Adtran to the the MM-8T1E1 card has gone bad. My question is, can I use a regular straight through cable or do I need to use some other type of patch cable (crossover or T1 crossover etc)
You need a straight through ethernet cable for the connection to the MX2800.
