TA9xx - Elevator Hot Line

[lanceallison21]

Looking to see if anyone has configured a TA900 for an elevator line, normally we configure these on our Meta but it's not an option on SIP protocol.

Customer picks up the line (fxs - pots) and dials a pre-determined number.

We are about to try this same application, so I will let you know how it goes. Please if anyone else knows anything please respond.

Here's a sample config snippet that should help you out:

voice user 8001

  connect fxs 0/1

  first-name "Elevator"

  last-name "Elevator"

  password "1234"

  hotline 555-5512

  sip-authentication password "1234"

The Hotline command tells the system to dial that number when phone goes off-hook.

By the way the above assumes you have working SIP trunks already and that you have an Adtran devices which does have FXS ports on it.  If you need more information let me know.

Hello and thanks for posting to our forum.

This should work without a hitch on the TA9XXs.  Make sure you have the following configured:

1. a dial plan entry that matches the hotline number (can be a wild card)

2. a voice user with the hotline number listed

3. a destination for the hotlined number to go (can be another voice user or through an accept in a grouped-trunk)

Below is a config where is x8030 picks up,x8035 is dialed.

voice dial-plan 5 extensions 803X

!

voice user 8030

  connect fxs 0/1

  hotline 8035

!

voice user 8035

connect fxs 0/2

Let us know if you have any questions.

Thank you both for your advice.

I was under the impression that a elevator line is just a regular phone line. I though the elevator has the hot line number programed inside of it. So the elevator takes the phone line off hook, and then dials the hotline number. In the configs provided above the elevator takes the line off hook, but then the Adtran dials the hot number right?

If I were to call the LEC, say Verizon or AT&T, and say I need elevator line installed would they ask me for the hotline number? I thought they would just deliver a regular POTS line.

I could see the hotline feature of the Adtran needed if you were using an old elevator with just a regular phone headset, but don't newer elevators program the hotline number directly into their elevator controls?

That would depend on what type of phone is in the elevator itself.  If the phone is a regular Analog phone with an autodialer just remove the hotline command and the Adtran will treat the line as a regular POTS line.

The building is going through a re-hab and they don't don't want to upgrade the elevator phone to have an "auto dialler" the elevator's are really old.

  I will try the config examples above.

lanceallison21,

     Any update on this issue?

John,

The client called asking for this feature and haven't heard back from them. I've been crazy busy with other items so I haven't had time to test. From the config example it looks really straight forward, I plan on testing this in the future.

Although the answers re hotline vs. autodialer-equipped phone are all very good from a technical point of view, from a safety standpoint be sure to think this through.

Elevator and alarm lines are needed to report unusual, emergency conditions.

Such a condition in the case of an elevator phone is a power outage.  Does the TA900 and all other gear associated with its connection back out to the telephone network (routers, modems, switches, etc.) have adequate backup power and are the backup batteries part of a rigorous inspection, testing, and maintenance program?

Or a fire.  What happens to the fire alarm line if the UPS powering the network closet catches fire?

Sometimes it's worth paying for one CO-powered plain old copper phone line.  You can share it between the elevator and the alarm with the proper RJ31X jack on the alarm system.
