Hello Everyone.

I have a backup pot line. If I plug a regular phone to the pot line I get a dial tone and I'm able to make calls. If I plug the Inter-Tel T1 to the pot line nothing happen, only a Red Alarm on the T1 card. I called the provider and they are no help. Do I have to make changes in the session manager, like adding the phone numbers?

Thank you in advanced for the help.

Why are you connecting a loop start line to a T1 card?

I'm a noob. Our previous phone guys had those pots line installed for backup, but I guess nobody check it. I was reading that we need to convert the pots line to a Basic Rate ISDN, and I don't know how to do that. Do I have to tell my provider to change the lines to ISDN?

What you need to do is get someone involved who has some telco knowledge. With the questions you are asking it is clear that you need help.

Where are you located?

What happened to the "previous phone guys"?

The post itself doesn't even make it clear what you are trying to accomplish!

You are trying to compare two vastly different types of service to each other. There is no "simple" way to convert a POTS line to an ISDN PRI. That is like trying to compare a roller skate to a semi-trailer.

Most likely, if back-up POTS lines were originally ordered, there may have been some thought in providing POTS trunk module (s) to accommodate the POTS lines.

The best advice anyone here can give you is to contact an Inter-Tel dealer in your area and have them resolve the issue for you.

Maybe the previous phone guys had the customer order a POTS line for remote programming and diagnostics.

As others have noted, T1 service and POTS service are two different animals and, typically, require different cards/modules to properly interface.

I am not Inter-Tel savvy, so, I would also suggest bringing in someone who has the proper training, and, can secure whatever is needed so the system functions as needed.

You need a InterTel tech or at least supply us with the proper info to help you.

What model system do you have?
What version software?
What cards are in the system?

We have an Inter-Tel Axxess Version 11. We have 4 T1, some DKSC16, PCMA, SLC. We have a primary phone line connected to the system and that's working. We want to have a backup line connection set up from a different company just in case the primary line goes down. For some reason our backup phone company put in pots lines, maybe because someone told them to. I tried talking to them, but since I don't know the right terminology they don't want to help. What would be the right terminology that I can use to tell them what we want?

Thanks,

I would imagine they put in a POTS line as backup since the cost of a backup PRI would be very high. You need to get the POTS line connected to your system and then if the main circuit goes down you call that company and have them forward calls to the POTS line.

In this day and age a single POTS line as a backup to a PRI is kind of silly. As soon as one call is taken or made and the line is busy all callers get busy. You would be far better off forwarding to a cell since calls will go to voicemail if it is in use.

If you want to go ahead with the POTS line since you have it you need someone who knows how to cross connect the line to your system and program it. This assumes you have a card that will accept a POTS line.

Upstateny is absolutely correct. It would be unlikely that you would have a complete backup PRI due to the cost involved alone.

A very common setup on systems that I have installed over the years would be to have a PRI and 4 backup POTS lines. You can set up with your carrier enhanced alternate routing. (Note: The name is probably different elsewhere and with different carriers). If your PRI went down for any reason, the main number would automatically route to the pilot number of this 4 (POTS) line backup hunt group. The phone system can be programmed to automatically use the backup hunt group for outbound as well.

It will not be full transparency. Your DID's will not route while the PRI is down and as upstateny alluded to, you would be limited to 4 paths inbound and outbound.

The POTS lines interface to the system via an LSC (Loop Start Card). If you need more than 4, you can also install a daughter board for up to 8 connections.

Check with your provider most of them offer backup services for PRIs

Thank you everyone for your response. I tried Stix1 subjection using the LSC and it work. Thank you once again.
