I take care of a system that has Premisys IMACS units in it. They are setup in pairs and each pair uses a single T1 circuit connected to their WAN Dual 8010 cards. In an effort to create a redundat T1 link I could really use some help in configuring the units to use the second T1 port when the other one fails (LOS and/or NOS). Or do I need to put in a second WAN card for the redundancy feature to work? If so, where can I get my hands on 10 of them and for how much? Am I at the right place here?
