Polycom video using BRI TN556B

[phonetekkie1]

Has anyone used a BRI TN556B for video. I have a PRI that I want to use for video. I know I can do it with an external CSU (Adtran 550) with BRI cards. Can the same thing be done with a PRI to DS-1 and broken out to this BRI card?

One more thing

This is on a S8710 V3 and I want to have 4 seperate Video conference units with there own DID's for video confernce calls. it will connect to a Polycom VSX3000

 

[phoneguy55]

I do this. TN556B is a 4 wire setup. Those 4 wires will give you 128Kbs. So, if you want to do 512K video via ISDN PRI you need 16 wires or 2 Cat 5 cables. With that said, wire 4 ports of you TN556B to your BRI MUX. If you don't have one you will need to order. About $1000 from Polycom. The BRI MUX has 4 ports. 1 for each 128K channel. The output is 1 RJ45, wire that directly to the polycom using the cable it came with.

To program you definity set up 4 DID's. Example 1000, 1001, 1002, 1003. The station type is wcbri. The rest should be default. I think thats it.

Thanks for the information.

Just to make sure.. You have DID's for the video calls over PRI and they are being split off of the BRI card. Have you seen any issue doing it this way? Any problems trouble shooting video calls?

I have the QBRI module from Polycom on the video units. That should take the BRI from the TN556B card right?

 

[phoneguy55]

Yes use DID's that are in order. Example 1000, 1001, 1002, 1003.

No real problems. Do you use AT&T for LD? If so, they have a global video conference data base. You call them and give them your DID's that you are using for video, they will load them into their data base to ensure calls will route correctly.

Trouble shooting is great, becuase you can use the list trace to see whats going on if necessary.

Yes. Cable 4 data modeules on the TN556B each with 4 wires to the BRI module. From there, cable the output RJ45 to the Polycom.

I do this at every sight I have. Our polycom have ISDN and H.323. We use H.323 for internal confencing and ISDN for outside of our company.

thank you for all of the information, this helps a lot.

 

[phonetekkie1]

can you print out your config to your TN556? Also, how did you punch down the wire to the units. I used the following on one port

WB WB
BW BW
WO WG
OW GW


Any help would be apprec

Is the Port: 01B0201 your BRI board?

I get "01b1101" May not mix BRI stations and trunks on one board; please select another

 

[phonetekkie1]

phoneguy thanks for the info, I got around this error

Did you setup a bri-board (add bri-trunk-board 01b11) ?

 

[phoneguy55]

just put the board in a open slot, it should come right up. Port 01b0201 is my PBX, yours will be 01b1101 as your fist data module, you second will be 01b1102, third 01b1103, and fourth 01b1104.


The first 2 pairs on the 110 block are port 01b1101, second 2 pairs on the 110 block are port 01b1102, etc...

1 1 2 2 3 3 4 4 5 5 6 6 7 7 8 8 9 9 10 10 11 11 12 12

Thanks again for your help

sorry for the extra question but I can't get the video unit to come up. The BRI light on the VSX3000 doesn't light up and the BRI stays down on the camera. I have Polycom and Avaya onsite trying to figure it out. I figure I'd come back to the experts on Tek-Tips

I have the BRI board installed and I have 2 data mod programmed with 2 DID extensions. I'm connecting the polycom unit straight off the back of the amph. The documentation tells me to use OW,WO,BW,WB. Can anyone tell me which pins on an RJ45 would I punch down on each of these wires. We are going on our 2nd day of this and both Polycom and Avaya can't answer this.

I know others are doing this. Please help

 

[phoneguy55]

Off of the TN556B you have an anphanol punched down w/b, w/o, w/g, w/b, w/s etc....

So the w/b and w/o pairs are your first data module. Wire the w/b to pins 4 and 5 on and RJ45 and w/o to pins 3 and 6 on the same RJ45. This is a USOC configuration. You will need to do this twice, 1 for each data module. So now take your USOC RJ45 and plug that into port 1 of your 4 port BRI mux, take you second RJ45 and plug that into port 2 of the BRI mux. Then the output of the BRI mux (a single RJ45) goes to the polycom's ISDN interface. On my polycom EX/FX that is right next to the on/off switch.

 

[phonetekkie1]

phoneguy55 you've been a big help so far

Let me make sure I understand

The Blue pair go to pins 4 and 5? Which pins does the white blue go to and which does the Blue white go to? The same for the orange pair.

I using this on a VSX3000 with the 4 port BRI built into the unit.

Do you know what protocol you use? Is it 5ess or NT-1?

Angain thank you for the feedback, you've help me more than Polycom and Avaya two days onsite

 

[phoneguy55]

It's USOC. So pin 3 will be w/o, pin 4 b/w, pin 5 w/b, pin 6 o/w.

I never used a VSX3000, but it should be the same. With the EX/FX you need an external BRI MUX, that I bought from Polycom for $1000.

Does the VSX3000 have 4 RJ45 ports on the rear for ISDN?

I don't remember the protocol to the Polycom. Try them all until you see the data modules come up.
