Remote system not detecting call termination 2

[ericbrunson]

I have a couple of analog lines from my 81c interfacing into a system that routes calls to intercoms. This system, from Rauland, is not detecting the termination of the call from the switch and it has been presented that the meridian does not drop the voltage on the line to signal the end of the call.

Does this sound correct to anyone on the forum and is there a setting in the switch to change this behavior?

Thanks,
e.

the voltage drop is not long enough for your remote equiptment, that causes the switch to see a remote request for dialtone after the call completion.. i would recogmend using did trunks for that application.. you'll see a longer tear down request and you have timers you can adjust in your route

In your Route Data Block, make sure your NEDC and FEDC prompts are set to ETH.

Thanks!

I'm not totally adept that dealing with anything but phones, but I poked around on the switch and it looks like we've got a universal trunk card we use for MOH that has 7 free ports on it. I'm thinking this is what you may mean by DID trunks?

I see several of them on another card have the NEDC and FEDC settings in use for the paging systems and I've looked up the control settings for the timers in the manuals.

Looking through our RDBs and Trunks, the only DIDs we have are ISDNs, so perhaps you could help me a little.

It looks like the first thing I would do is go into LD 16 and set up a NEW RDB. Then, I thought I would go into LD 14 and create a block of DID trunks (I need 6 outgoing lines). I'm stuck understanding the relation of the ATDN and the ACOD and whether I need to create an ACD for the dialed extension.

I need a single extension to use the outoing trunks as a rotary to ring the far end, that's about it. I initially set the ACOD on the RDB to the number I want them to dial and set AUTO to YES because I don't want any calls to go to the console. However, in LD 14 when I'm prompted for the ATDN I get schwartzed that the number doesn't exist. Do I need to create an ACD? Because when I tried that it wouldn't allow me to use the ACOD of the RDB.

I'm reading it again and I think the AUTO is refering to incoming calls (which there won't be any), but I'm not sure if setting up an ACD is the correct thing to do, since the manual makes reference to using a Hung Group steering DN. Right now, I feel like anything I can think of is just shooting from the hip. Can someone show me where I went astray.

Thanks in advance,
e.

i would use a dsc or lsc in load 87 to call the remote end, that will let you use enter the route number to send the digits to. you'll need to be set up to receive digits onthe remote end. if not set the far end up as auto term to a working number.. either way build a route.. did iao or cot, the acod is a unique number that can be used to direct access a trunk if you need to manually insert digits, mostley for testing.. just use any vacant number from ludn. other then that asup=no icog=iao return past everything else except acod.. then put the trunks in as loop start if your getting dialtone from the remote end..

John,

Thanks for the detailed response, but I think it may be more involved that what I need. The remote end will not issue dialtone, the device is more like a modem than a switch, just answering the call when it detects ring (is that loop start?)

There's much in your answer that I don't understand, but basically I just need to ring the remote end and maintain the call until the local end hangs up. Is all that you discussed necessary? I'll delve into the manuals a bit more while I'm waiting.

Thanks,
e.

your right, not a trunk to trunk app.. you can supply dial tone for the ckt and ring current.. are the calls to this all short?.. if so you can route them through a rdb with a tfd (timed forced disco) set to 4 or 5 minutes (works great for paging) try marking you analog sets xfd.. thfd is default but that may need changing..
