Creating a Talk Loop

Have one for you old school phone guys out there. I just cut over a 61c to a s8720. The site is a horse track that has 8 TV towers around the track manned by cameramen who televise the race to all the OTB's. The towers are equipped with old 2554 sets that each have an individual extension and were also able to dial a TAC code on the old 61c and get on to a talk loop. The talk loop on the 61c was 20v filtered talk battery from an old Western Electric and was looped in and out of the ports on the 61c trunk card. When I try to replicate this on a 747b in a test switch I start to smell caps burning up on the card after 5 minutes. Anyone have any ideas at replicating this?

thanks
 
Just a thought...

How about looping multiple analog phones to 1 port/extension... say 4 of them on 1 extension, then the other 4 on another extension. Then to join up together one person on each extension would dial a VDN that was setup as a meet me bridge with no "authentication" just straight to a "route to meetme" step. If the other phones pickup they should be online. If they hear dial tone, they should dial the Meetme VDN.....to "join their leg of phones". Of course in this senario, 4 phones would share 1 extension (could be a bummer). The Meet me limit is 6 attendees, this would take 2 slots. So you could have more people join if needed.

A bit extreme...but it might work. I would test it out before making all your cross connects... I've used this method on analog extensions where the CPU dials home to update software.....saves RTU's (5 modems using 1 extension).

------Fellow PBX peers, feel free to slaughter my suggestion :) if you think it will not work or comment otherwise.

Being you were the first "old school phone guy" LMAO to reply, I woundn't dare talk bad about your solution. Besides I was taught to have respect for my elders. [wink]

Now to the problem.

Why not small digital sets with a conference button. It seems that is all they are trying to accomplish is it not?

LOL... I'm 36 and counting, my tenure in the Avaya PBX world is 10 years.

The issue with digital and conference is that they would only be able to get 6 people joined up... He needs at least 8...

You are right on the amount on a conference call so that wont work. And being I am a little older then you (not telling you how old you youngster), welcome to the old young guys club....

Thanks guys for responding. I thought of conferencing also but alas that six party thing got me. What do you think of chaining to meet-me-conferences together? Lets say get six going on one and have the last guy conference in the other vdn with the other two parties. Tomorrow I'll try it as I'll be on site. I'm also going to try a Viking PS-48-RGA that will give me 48v talk battery at up to 150ma and see if I can make some smoke. I have a couple of old boards to play with. If we get this working maybe we can go into the poor mans conference bridge business!
 
Using meet me that way will only work if you dial out your PSTN, then back into another meet me bridge joining the two via conference. The PBX won't let you do that internally. It would work as mentioned... though some echoing can occur. Plus it can be a pain to manage.

There is always the option of an outside audio bridge provider... or upgrading to a Avaya Meeting Exchange setup ($$$$$$.$$) An outside provider is usually on order of .05 - .08 cents a minute per caller.

Do the cameramen talk to each other or just listen to a director. If they just listen then create a group page. Dial the group page number and all sets are connected via speakerphone in a listen only mode. If they have to talk back you can use a Valcom one zone talkback paging system.

1a2 to ip I seen it all
 
Have you tried setting up a term-ext-grp. TEG's can group up to four extensions together on the same call. I have not had the time to see if you could conference two of the groups together. I might try this tomorrow.

Tried the Viking unit and made more smoke. I think the 747 board doesn't like positive battery. I'm going to propose a small Ip office configured as a conf bridge at this point. Thanks everybody for your help and suggestions
