Nortel 81C Tie Trunk need help 1

[mrnme]

greetings....

I have a vendor install duel T1 card and defined the tie trunk on that T1. for some reason the ALARM STATUS is RED and it does not communicate for our CISCO phone system. Please help. Thanks.

Do you have a loopback jack? If so unplug the patch cord from the cisco end and put the loop on it to see if things start working. If not work your way through all the connections until either your loop back works or you prove the hardware/programming is the issue. You might want to do the same thing towards the Cisco too to make sure that works.

Red Alarm signifies that the hardware is not recieving a valid T1 signal. Verify your cable connections, make sure the loop is enabled, and then test with a loop back plug (You want to loop your transmit from the Dual PRI back into the receive).

Swap the transmit and recieve pairs on one end. Both PBXs are wired to connect to telco. Swap Pins 1 and 2 with 4 and 5 on the 8 conductor modular connector.

i am sorry, i am not at the site, but i think the vendor define it wrong. I think it should be a PRI TRK and not a DTI. we have a tie trunk to option 11C which is working fine. I think this should be the same. please see the definition for the CISCO.

and this is for the option 11C

Thanks.

Yep, I would out it and rebuild it as a PRI, using QSIG.

 

[mrnme]

would you please give me the command and how to do it if it is not extensive procedure.
Thank you.

 

[jamie2]

I assume you are on a large system since the vendor installed a dual pri. Do you have a MSDL card in the system, or do you recall the tech. telling you their were daughterboards?

 

[jamie2]

There are some steps below, but you should post your info. first so we can walk you through it easier and see what you have for resources.

RDBs,Trunks,CEQU info,MSDL info from ld 48.

1. LD 60 - Disable the Loop 60
2. LD 14 - Out the trunks
3. Ld 16 - Out the Route
4. LD 17 - Out the loop under 'CEQU'
6. LD 17 - Rebuild the loop under 'CEQU'
7. LD 17 - Build the D-Channel under 'ADAN'
8. LD 16 - Build your route
9. LD 14 - Build the trunks
10. LD 96 - ENL the MSDL
11. LD 60 - ENLL 60

you are great. thak you for taking time to respond to my questions. yes, it is 81c and I bought this card and the vendor installed it.

Nortel Merdian Duel PR1 Module (NT5D12AB)

The vendor did not tell me anything about daughter board.

 

[Wane47]

red alarm doesn't have anything to do with d-channel. One or the other of your vendors has to flip the transmit and receive on their equipment. a pri will float to a reqular
T-1 if both are esf/b8zs. they won't talk but they will float.

Thank you everyone. it is working now.
