PRI Line not Working 2

[Olisa]

Hi,
I have IP412 with dual PRI card. We use one line only and have set it to network. It has been working well for one year then suddenly it went down and alarms went red. The TSP can and did something on his line and modem and lights went back to green. But calls cannot come in or go out. He says the problem is my PBX and my line is fine but channels are blocked. Have tried changing to use the second line but still the same.

Below is a trace from Monitor.

kindly advice? Is fault really mine or the TSP? What does Falc mean? and crc=1 ?

Change the CRC setting and reboot, test again

PRI Line 1 (peb=1) has gone from the F1 state (normal Operational state) to the F2 state (Fault condition 1 state - receiving RAI or receiving CRC errors). Back and forth.

Thank you for your quick response.
So the problem is CRC errors? What is causing them? Should I uncheck the check CRC errors option? Will this make it work even with errors? Pls advice.

This depends on the Provider.

Some send a CRC (cyclic redundancy check)and some don't, if they do send it then you need to turn it on if they don't turn it off.

A CRC-enabled device calculates a short, fixed-length binary sequence, known as the CRC code or just CRC, for each block of data and sends or stores them both together. When a block is read or received the device repeats the calculation; if the new CRC does not match the one calculated earlier, then the block contains a data error and the device may take corrective action such as rereading or requesting the block be sent again

We always let the Provider turn on "CRC", here in the Netherlands we have the best experience if it's turned on.

Thanks Bas1234. Am in Somalia, and not sure what the provider has on his end but will try uncheck and see. But the device has been working well for over a year now till suddenly this came up. Could the STP have changed something on their end that they are not admitting? Thanks for your insight.

 

[Olisa]

thank you all for your assistance and support. The problem is solved. It was on the TSP side. He had badly crimpped the cables coming to my side. He corrected it and am now fine. Asante!
