Hello, can anyone help?
I look after a Voice Dealing system that is connected to some IAB Channel Banks in Tokyo (Via Eastern Research network).
DS0 Connections on a particular Channel Bank/Slot (CB2 C) are causing the Dealing system to constantly signal.
The Bit pattern that causes the Dealing system to signal is 0101 therefore we think the Channel Bank is streaming this Bit pattern.
We have bought a EXFO Puma T1 Tester to test this but really haven't used this tester before as this is a little bit new to me.
Looking at the Tester manual it looks like we want to use T1 monitor mode but apart from that i don't know too much about this.

Has anyone got any experience on this sort of issue?

Thanks if you can help!
