What's the command to test my side of DS1? 2

[1SIKV35]

I'm trying to install a new DS1 ISDN-PRI trunk using a TN464HP circuit pack. I've done all the configurations and the circuit path is good, but when I status the trunk, I get "out-of-service-NE".

My distant end will be a Nortel MSL-100 (still waiting for technician to connect his end), but while he's doing that, is there a way to test my end?

What's the command to test my side of the DS1 just to make sure I did it right? Do I have to do anything with my loopback jack?

Any help is appreciated.

Thanks.

Get the board location for the DS1 - and then test board 1b14 (for example)... look for test 138 if it passes, that's usually a good indicator your side is up.

I thought there was something I had to do with the CSU or loopback cable to loop the signal back on my side?

I did a "test trunk 1" and the following came back
Port: 01A15xx
Maint name: ISDN-TRK
Alt name: 01/xx

Test No.: 36
Result: PASS
Error Code:

Test No.: 255
Result: FAIL
Error Code: 8

Test No.: 256
Result: ABORT
Error Code: 1113

Test No.: 257
Result: ABORT
Error Code: 1116

Sorry it's not in the normal format, but all trunk members had the same results.

I'm not near my terminal so I'll run a "test board 01A15" as soon as I can.

I did a "test board 01A15" and it failed test 138, but it passed the rest. Here's the results:

Port Maint Name Test No. Result
01A15 UDS1-BD 138 FAIL
01A15 UDS1-BD 139 PASS
01A15 UDS1-BD 140 PASS
01A15 UDS1-BD 141 PASS
01A15 UDS1-BD 142 PASS
01A15 UDS1-BD 143 PASS
01A15 UDS1-BD 143 PASS
01A15 UDS1-BD 144 PASS
01A15 UDS1-BD 145 PASS
01A15 UDS1-BD 146 PASS
01A15 UDS1-BD 1227 PASS

Then it continues with the test trunk results in previous post.

Does that mean problem is on my end, or is it because other end isn't up yet?

If it's my end, what's test 138 and how can I fix?

Thanks.

Loss of Signal Alarm Inquiry Test (#138)

FAIL The board detects a Loss of Signal alarm. The physical link is broken or the remote DS1 endpoint is down. All trunks or ports of this board are out-of-service.

I haven't done this in some time, but I believe you can create a loopback RJ45 and place it in the network jack of the CSU and then run that test again. It should loop the CSU.

How do you find out what the test number mean?

01A15 UDS1-BD 138 FAIL
01A15 UDS1-BD 139 PASS
01A15 UDS1-BD 140 PASS
01A15 UDS1-BD 141 PASS
01A15 UDS1-BD 142 PASS
01A15 UDS1-BD 143 PASS
01A15 UDS1-BD 143 PASS
01A15 UDS1-BD 144 PASS
01A15 UDS1-BD 145 PASS
01A15 UDS1-BD 146 PASS
01A15 UDS1-BD 1227 PASS

So does failure of test 138 mean it's on my side?

 

[1SIKV35]

Anybody there?

When we have gotten the 138-139 error, more times then not it has been the connection on our side; bad cable, fipped pairs, bad connections at the Dmarc. I would do a loop back to help isolate, for each connection.

 

[1SIKV35]

Thanks TPhoneD. So my question is how to do a loop back? I know it's a stupid question, but I've never done this (just kind of given this new duty at the last minute).

So how do I do a loop back test to isolate?

Thanks.

take an rj45 connector, male or female depeding on where you are going to use it, and jumper or connect the white orange pair straight to the white green pair, or in other words pin 1 to pin 4 and pin 2 to pin 5, I think.

 

[Esmerelda]

I place a "loopback jack" (cigar shaped thing with a light on the end of it....can't remember what it's really called)at the DMARC, busy the board,loop the jack up via commands from the PBX (test ds1-loop xxxxx cpe-loopback-jack-begin), and, then run the list meas ds1 xxxxx commands. I end the test by dropping the loop (test ds1-loop xxxxx end-cpe-loopback-jack-test). Another way of knowing if the other end is good is whether you are able to successfully drop your loopback. If the loopback doesn't drop, you hae to reset the board, and, then release it. (While it is looped up, you can "test ds1-loop xxxxx i" to inject errors, and, then, list measurement, and, you should see your error.)

 

[1SIKV35]

2BAvoice, do you mean connect the white orange pair to the "white blue" pair? Pins 1,2,4 & 5 are the orange and blue pairs?

Is this what you mean?

Pin 1 white orange to pin 4 blue
Pin 2 orange to pin 5 white blue

Thanks for you help...I really appreciate it.

 

[1SIKV35]

Does the avaya loopback jack do this for me?

 

[jimmax]

Change the CSU type to integrated. That'll be the fix.

 

[2BAvoice]

sorry about the pins, the colors were correct, should have been pins 1 and 2 to pins 3 and 6...white orange to white green.

 

[pepsisparky]

Actually, if it is a T1 then the pairs in use are the blue and orange (1,2,4,5). Blue is network side recieve and orange being network side transmit. If you hard wire the pairs together, it will loopup your ds1 board , but the pin out to you ds1 board may still be backwards, depending on the local providers tech's installing the T correctly.
