Programming is on the MICS, not the software. You could backup programming and restore it to the replacement. I've seen one or two cabinets with bad MOH circuits, and a handful of bad paging circuits. Try amplifying the music input and see if you hear anything. Also try dewey's suggestion. It very well could be a bad amphenol.
I've seen 'em blown, too. I usually test with a toner at the block to ensure the port is shot, and not just bad wiring from the MOH source. Double checking the Amphenol is a good idea, too.
Had low volume issues with my CICS....switching tip and ring did the trick.
Also....maybe a problem with the BIX 1A. I did a new install once on a MICS, 8X32. We connected all the trunk lines in, and found that lines didn't work. After a bunch of testing, we thought maybe somehow we got a ground start card instead of a loop start card, but that wasn't the case.
We noticed the lines were dead at the I.T. with the handset...that is, dead until we unplugged them from the input bix field to the KSU. If we connected L1 to co line 1, 2, 3, or 4 input, it worked fine....it's when we started connecting multiple lines we had trouble.
L1 - okay
L1 + L2 connected, both lines became noisy
L1 + L2 + L3, all lines shorted out, none would work
L1 + L2 + L3 + L4, all lines shorted out.
Replaced bix 1A on end of AMP cable and all is well.....talk about a tough day of troubleshooting!
Thanks all for your valuable input. The issue was caused by a bad AMP cable. The pins were not making a connection. Thanks for all your help it is very much apperciated.
Hello Yall,
I am not a phone technician, but I work with phone technicians who install our MOH equipment all over the USA. Please forgive me if I'am asking simple questions. I do have three clients with the same exact issue: barely can hear the music on from the MOH port. My questios are:
What is the Amphenol?
What is the AMP cable?
The issue was resolved with two clients by using a volume booster, but the third one is not having any luck.
AMP cable is short for Amphenol cable. It's a standardized telephony cable that has 25 pairs of wire. It attaches to the telephone system and punches down on 110/66/Bix blocks and allows the telephone system to connect to the telephone station wiring, telco wiring, paging, and MOH.
Wow...that's going to make my client very happy...thanks again Master Dewey; you already helped me above and beyond my expectations.
By the way; could you recommend a book, or a technical source to help me get up to speed on troubleshooting telephone system MOH issues and installation tips?
We usually hire technicians throughout the country to install our MOH units...However we do the initial troubleshooting steps before we refer the client to their phone vendor, or dispatch one on their behalf. I just transitioned into this position...which is why I know very little.
I don't know of any "how to" manual for MOH. Every phone system is different. Some connect via jumper wire to a block, others use RCA, 1/8" plugs, or a combination of both.
There's usually programming involved on the switch, too. Your best bet is to get a good tech on site if there are issues.
