Conferencing on an 81C 1

[phnechic]

Can anyone tell me how to calculate the number of simultaneous conference calls we could have at one time on an Option 81C?

 

[johnpoole]

depends on the number of conf cards you have.. ld 22 prt cequ

The number of timeslots is limited to 30 per conference loop. For
Small Systems, a maximum of five simultaneous conferences, each
consisting of six conference users, is supported per conference loop.

 

[phnechic]

CONF * 001 * 017 * 059

So, if is it possible to add conference loops to gain more capacity?

What is it your tring to do?

 

[phnechic]

I've been asked to develop a DR plan in which the employees in the region are leveled by a contagious virus. Part of the plan is determining how many simultaneous teleconferences we could have if we decided to use our in house solution as opposed to outsourcing.

 

[acewarlock]

How many simultaneous teleconferences is theoretical and based on serval factors. Are they all internal or External, if external, are there enough trunks to handle these conf call's plus all regular calls. Nortel make a special conf card that can handle more then 32 conferees at 1 time.

Thank you!

PS I think it's called a MICB
(Meridian intergrated confercence bridge)

Court,

Keep in mind you cannot currently initiate a conference call as an outside caller. Someone at CORP would have to be coordinating the calls, which would take up one resource and require someone to be on site. Also, you cannot combine conferences (as I once thought), so 6 total people is the max you could have on a single call.

The MICB is an good option, since you have so many inbound trunks. It is a dual-slot card and requires a TN for each port, plus one or two additonal DN's for dial in numbers. The more simultaneous conferences you want, the more pilot DN's you will need. I think when I priced it out it was around $5,000. You can link two together and get up to 62 ports, but then you need an additional server to run and manage the conference bridge. here is a link for a decent white paper.

Hope this helps,

You can read up on the Meridian Integrated Conference
Bridge, in the 553-3001-358 Service Implementation Guide

For "disaster". we have people disl into a third party confer bridge. In the case of plauge/virus, the PBX would probably be running, but so many other types of disaster increase the chance of my main PBX going down. It came down to the confer bridge that would be least likely affected by situations likely to hit our main site.

Not every company needs to go that far.

Hate to disagree with you, but the MICB is a single slot card. I've just had to replace mine. It can also be run back to back with a second card for a total or 64 ports.

 

[srmega41]

Don't hate to disagree if I am wrong!! Did the older ones used to be a dual slot, like the line-side T1 cards? It has been quite a while since I looked at them, so I was trying to rememeber, and even look for them. I did not find anything on the newer cards, but I thought I remembered the original units being dual slot, since they use 32 TN's.

Thanks for the correction, I would rather know I was wrong than think I am right and others know I am wrong.

The new cards are an NT5D51 and they are single slot 32 ports. Each port is programmed to emulate a 2616 ACD set.

 

[srmega41]

Do you use the 16 data ports on that slot, or do they burn the TN's on the next slot over?

 

[TAnselm]

All 32 ports are on the single card. They are all listed as voice ports. For instance our is in slot 92 0 15 and here is the ld 32 stat:

.stat 92 0 15
00 = UNIT 00 = IDLE (2616 LOG IN )
01 = UNIT 01 = IDLE (2616 LOG IN )
02 = UNIT 02 = IDLE (2616 LOG IN )
03 = UNIT 03 = IDLE (2616 LOG IN )
04 = UNIT 04 = IDLE (2616 LOG IN )
05 = UNIT 05 = IDLE (2616 LOG IN )
06 = UNIT 06 = IDLE (2616 LOG IN )
07 = UNIT 07 = IDLE (2616 LOG IN )
08 = UNIT 08 = IDLE (2616 LOG IN )
09 = UNIT 09 = IDLE (2616 LOG IN )
10 = UNIT 10 = IDLE (2616 LOG IN )
11 = UNIT 11 = IDLE (2616 LOG IN )
12 = UNIT 12 = IDLE (2616 LOG IN )
13 = UNIT 13 = IDLE (2616 LOG IN )
14 = UNIT 14 = IDLE (2616 LOG IN )
15 = UNIT 15 = IDLE (2616 LOG IN )
16 = UNIT 16 = IDLE (2616 LOG IN )
17 = UNIT 17 = IDLE (2616 LOG IN )
18 = UNIT 18 = IDLE (2616 LOG IN )
19 = UNIT 19 = IDLE (2616 LOG IN )
20 = UNIT 20 = IDLE (2616 LOG IN )
21 = UNIT 21 = IDLE (2616 LOG IN )
22 = UNIT 22 = IDLE (2616 LOG IN )
23 = UNIT 23 = IDLE (2616 LOG IN )
24 = UNIT 24 = IDLE (2616 LOG IN )
25 = UNIT 25 = IDLE (2616 LOG IN )
26 = UNIT 26 = IDLE (2616 LOG IN )
27 = UNIT 27 = IDLE (2616 LOG IN )
28 = UNIT 28 = IDLE (2616 LOG IN )
29 = UNIT 29 = IDLE (2616 LOG IN )
30 = UNIT 30 = IDLE (2616 LOG IN )
31 = UNIT 31 = IDLE (2616 LOG IN )
