norstar 824 with dr5 with amphenol harmonica

[rwilliamstele]

Hello everyone

I have a norstar 824 that i am using two 50 pin amphenol connectors with 8port 6 conductor harmonica.

I am using one for the extension card. it work's fine

The issue is with the one holding the phone lines.

When i push the button assign to access a line,i hear the internal click from the key service unit, but there is no dial tone. When i dial a call from the outside i can hear the box trying to pick up the line but it dosen't ring on any lines.

there is no tech to punch down lines..that is why everything is modular.

I suspect it could be a problem with line posistion on the cable....any ideas

thanks
Robert

It sounds like you could have a bad port on the line card. Try swapping your line 1 and line 2. If the line works on the other port, you may have to swap it to an unused one.

See faq 799-1780

My guess is that you are on the right track and your harmonica configuration and jumper breakout are not matching up pairs.

If you are breaking out 8 6p6c from 50 pin amp and then using an rj11 to jump from harmonica to a rj11 jack on your trunk on your demarc, you would most likely have the 3 pairs for lines 1,2 and 3 in your harmonica jack #1, but when jumping to your demarc in this example, you would only have one pair actually connect to a trunk. In jack #2 on the harmonica, you would have lines 4,5 and 6 and again when you jumped, you would only have one pair connect to a trunk.

If you have to go this modular route, you might be better served to use a breakout box that went from 50 pin amphenol to 25 rj-11 jacks wires as 6p2c-- that is each pair from the 50 pin ends as only one pair in each rj11. Or, you could get an octopus that has 50 pin amp on one end and then terminates in 25 rj11 plugs, each having one pair.

If you check you DN's, you will probably find that there are gaps in your extension sequence as well. However, with the assumption of 3 extensions for harmonica jack, 3 x 8 is 24, so if you have 8 or fewer extensions, they will work just fine, but they will not be sequential.

Also, bear in mind that there are a variety of different pinning configurations for those harmonica breakouts and I would start with understanding the correspondence of the 50 amp to the harmonica jacks first.

Just my 2 cents.

I guess the real question is was it working before? Line 1 pins out on w/bl, line 2 on w/or, line 3 on w/gr, etc...

If it was working before, check to make sure you're making good connection on the amphenol. If you are, then you've got a bad line, or a bad port.

I agree with missed. Get yourself a couple of small boards that break a 25pr. Amphenol out to 25 RJ11 individual jacks, and it will be like a mini-patch panel. Your skipping ports on the lines and stations, and it's gonna forever cause you a headache.

thanks guys

where is the best place to buy the breakout

Google the following and find the best pricing:

Leviton Mini Patch Panel break out box - 6 Pos. 2 Cond. USOC 25-Pair Male Connector

OCTOPUS Cable - 25 2 Conductor Modular Plugs to a MALE AMP Connector

The patch panel will look like a box about the size of a paperback book with one amphenol connector and 25 rj11 connectors. Be sure to observe gender for the box connector (some boxes have two amps, one M one F) so that you can have the right telco cable to go from the 824 to the panel.

The octopus will look like an amphenol connector with 25 cables (several feet long) coming out of it each one terminating in a rj11 plug (2 wires per plug). Again, watch gender of amp to match your 824 and any connect cables.

There are a number of vendors. I was told that forum rules tend to frown on posting particular suppliers.

I suggest double-checking the configuration to ensure that you will get a full pair, but only one pair, from the amphenol connector to the "two center pins" on a rj11; so that you can connect things one pair at-a-time. If you have more than one pair pinning out in an rj11, you will have the exact same problem.

I may not have been clear on the octopus.

Amp connector will breakout into to 25 cables.
Each cable is a 2-wire cable.
Each of the 25 cables will terminate with an rj11 plug.


Each plug will have only the 2 wires/leads (center positions) from one of the 25 cables -- so in total you end up with 25 rj11 plugs each one having only one pair present.

8X24 requires a female Amphenol connector. So, if you have a normal Amphenol cable (male-female), your Leviton needs to be female.
