Auto Ring Downs via T-1

[mreillyeci]

Our clients have multiple Auto Ring Downs (ARD)s and bring the ARDs to the office using a T1. The T1 is terminated on a channel bank and the hand off to the Avaya switch (from the channel bank)are analog CO trunks. We want to terminate the T1 directly into the Avaya switch eliminating the channel bank.

Will this work with the Automatic Ring Downs considering the signaling leads?

What type of channel bank and line cards are you using? Do you know what the T1 signalling format is, as in T1 E&M or other? So the far end goes off hook out in the world somewhere and this seizes an incoming T1 circuit, yes? Then the channel bank sends ringing to the CO card on the Avaya? Or are the ringdowns outgoing?

 

[mreillyeci]

The channel bank that we are looking to bypass is usually supplied by the carrier. Since we take the ARDs in as CO trunks we haven't been involved in the programming of the T1 on the network side. If we can terminate the T directly into the Avaya switch, then the T-1 trunk group will have to be set up accordingly.

the ARDs are usually outbound from our client to a large brokerage house. However the ARDs are usually set up as two way circuits thus signaling will need to be sent in both directions.

It will work, you'll just need to take a guess at the settings. I had a similar "vanilla" scenario with a LEC supplied channel bank for POTS service. The T1 was not surprisingly b8zs/esf but the trunk group type required to get it working was:

Group Number: 10 Group Type: co CDR Reports: y
Group Name: OUTSIDE CALLER COR: 1 TN: 1 TAC: #50
Direction: two-way Outgoing Display? n
Dial Access? y Busy Threshold: 99 Night Service: 200
Queue Length: 0 Country: 1 Incoming Destination: 200
Comm Type: voice Auth Code? n Digit Absorption List:
Prefix-1? y Trunk Flash? n Toll Restricted? y

TRUNK PARAMETERS
Trunk Type: loop-start
Outgoing Dial Type: tone Cut-Through? n
Trunk Termination: rc Disconnect Timing(msec): 500

Auto Guard? n Call Still Held? n Sig Bit Inversion: none
Analog Loss Group: 6 Digital Loss Group: 11
Trunk Gain: high

Disconnect Supervision - In? y Out? n Cyclical Hunt? y
Answer Supervision Timeout: 0 Receive Answer Supervision? y

You might also try setting them up as DS1FD. Each channel in the ARD T1 would be setup as phone type DS1FD, and would vaguely resemble a 2500 set.

Using this method, you could create hotline destinations (like bridged extensions on a large phone) that would behave just like a ringdown circuit. (So when a call signals in, it would automatically seek a particular destination.) Each could also be addressed by calling the inside extension you assign to the channel. (or setting up a hotline destination for the bridged extensions)

A bit messy, but it could make a large phone resemble a turret.

Frankly I never understood turrets. What's wrong with a speed dial button?

Carpe dialem! (Seize the line!)

Thanks for the suggestions.

May I ask what you ports int he trunk look like or if anyone has this for say a POTS or analog line instead of a T?
