I am having an issue with a new carrier for 3 digital PRI lines. I am attempted to determine if it?s a carrier issue.
The equipment we have:
1) Cat 6500 Core
2) 6808 module connected to it for the digital t1
The new carrier sent us 3 PRI?s with one trunk group and its sharing the D channel. It appears with the equipment I have, each pri will need its own D channel to function properly. So the carrier needs to reorder these lines.
Now the problem I was getting, only 1 T came up and the other two are down/down.
I started to think, I know the d channel is an issue and I need a d channel for each. But would that cause the lines to be down/down. When you go into the call manager and look at the t?s. They are bouncing up/down almost every sec.
On one of them I keep getting
Transmitter is sending Normal Signal
Receiver has Abnormal
Transmitter is sending Remote Alarm
Receiver has Frame Sync Loss
And it resets. Now this is layer one correct? Shouldn?t it at least come up or with my D channel issue cause this?
