Question about Carrier Access Bank I Multiplexer (930-0002)
I have a Carrier Access Corporation Access Bank 1 T1 channel bank. I am switching T1 carriers and on the new T1 the analog sets that are connected constantly ring. I can go off-hook on any one of them and get dialtone though. The new carrier says that commonly they need to have the vender change their equipment to 4 wire E&M signalling instead of Loop or Ground start. I cannot seem to find where I can change this setting. The line coding and framing are all correct, so it seems that this would be the issue but I don't know if the channel bank can do it.
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).
click here to download the app (for users in the US for now) and get all the help you need.
