Ring down circuit 2

[Mugsiensedgwick]

I am in a hospital. We have a ring down circuit which connects us to the Sheriff's office and vice versa. The circuit is down and I can't find the circuit ID.
I'm not even sure whether we're paying for it or the Sheriff.
I know that there is a bell standard for naming this kind of circuit but I don't know what it is.
For instance HCPA is a 1.544 mb t-1 circuit, and If I remember correctly DCPA is a 56 KB digital circuit.
Anyway I am wondering if anyone can tell me what the nomenclature for a ring down circuit is?
I can't turn in a trouble report until I know the ckt ID.
Thanks,
-Randy

- Are you on a telephone system? Some phone systems can be labeled with numbers per line.
- Ring Down Circuit... is that a direct dial?
Meaning you pick up the phone and it just calls them without having to dial anything?
- What is happening? You pick up the phone... what is supposed to happen? It maybe on the Sheriff's side not yours.

If it is a direct analog line, attached to a phone, it is possible that a Technician can make it out and tone out the circuit.
Sometimes the technicians leave numbers in the main telephone room that they can refer to that line later for ease to find circuits later... or they can call the ILEC (telco) to find information.


The more information you can give the easier it is to assess.

Key point in above is how do you access the line.

The "Ring Down" could be initiated by your PBX

or

The "Ring Down" could be Telco controlled.

I suspect the latter, but the former has legs too.

Ring down circuits are private analog lines typically not going through a PBX. It's a kind of "red phone" arrangement where if I pick up the receiver on one end, it automatically rings on the other.

 

[Mugsiensedgwick]

There is ac powered equipment on both ends to accomplish the ringing.

 

[kwbMitel]

You might be surprised at how many ways there are to accomplish this task. Yours is but one of many.

As you've stated, this is a dedicated cct. As it will not have a phone number and you do not know the cct number and you do not even know who owns the line, your challenge may be quite great.

Contact your local Telco. They will need to come to site (either site) and determine how to proceed from there.

So it could be 82OSNCxxxxxx. Look around. The ringdown hardware ought to have a circuit ID on it. The hardware may be in the C.O. and all you get is a cable pair, but somewhere, it ought to be identified.

This type of ckt is called a "2-way automatic ringdown ckt". Sometimes it is called a "P-line" or hotline. A couple of tips, check with the hospital's accounting department, and go through the phone bills looking for private line ckt accounts. Do they have any cost centers assigned to phone lines or ckts or even a database that may provide some leads? Next, have you identified the Binding Post or cable and pair @ the MPOE? Is there any kind of record showing an inventory of what is assigned on the pairs @ the MPOE terminal? If those fail, and you can identify the BP or CP then contact telco to find out what is assigned to that Cable Pair. In some cases you may have to get telco to come out and tag everything in the terminal, or plant engineering could sent an inventory of the pair assignments for the cable serving that building.

You might even have to contact the sheriff's office and go there to see if their end has the ckt ID tagged on the pair. Or their communications person may have it available in a database or list.

Hope this helps!

if there are ring generators on both ends it might be a
OSNA circuit it may even have red booties on it to id it on the binder posts or rj21x

 

[SYQUEST]

If it's telco provided, the ring generators are in the CO.

We have several ring down circuits like you refer to from fire stations to the E911. 7 circuits to be exact. All of them have circuit ID's. We use AT&T in Illinois and the circuit are all similar. They all look like this 5PLNT0000XX
The XX are realy numbers but I omited them since you do not need to know acuall circuit ID.
The ring generators are in the TELCO/CO. Nothing on site except a pair of wires that are terminated on the demarc.
good luck finding the circuit id. The Telcom should be able to help you or you can check your billing department.
Request a SLA for all numbers and circuits from Telco.

 

[Mugsiensedgwick]

Thanks SNSSMIS. The 5PLNT0000XX was exactly what I needed.
In Kansas the ckts start with 71 or 72, instead of 5. If I remember correctly the first two designate the LATA.
We have quite a few circuits and it's hard to tell which is what. By the way Syquest, even though it's telco provided, the ring gen is not in the CO. The Ckt wouldn't necessarily have to go into the CO. This particular DOES go there but only because the CO is in between the end points.
I hope this clarifies some of this.
Thanks all of you for your suggestions,
-Randy

No, it has nothing to do with LATAs! The first two numbers are the PCO or Plant Control Office code, or in some areas LAC (Local Area Control code). The next section of the ckt ID consists of four letters. They indicate the ckt type: private line voice, DS1, or DDS, and other indicators, such as interstate or intrastate, etc. The next section is either a six digit serial or nine digit serial, that can be provider specific in some jurisdictions. The optional suffix of two letters indicates the operating company where the ckt originates. Although, in the old GTE areas, they used GTCA as a suffix, as did some of the other non-Bell companies.

Hope that clears up some of the confusion.

[Mugsiensedgwick]

Yes I believe you're right. Thanks for clarifying that.
Been too many years....
And not enough years...
LOL

 

[SNSSMIS]

Hope you got the circuit back up and ringing down.
