Tandberg MCU Connection

[gbroo]

Good Day,
Does anyone have a suggestion for the best solution for the PRI to RS-449/RS-530 connection.

Somthing like this perhaps??

HOWEVER!

I doubt that you can get ANY dialing information over that link, I belive it's just a 2Mbit E1 converter. Not a PRI converter. So it probably isn't what you are looking for!

Welcome to the forums gbroo!

Well the first device that pops into mind is the Adtran Atlas 550. ( http://www.provantage.com/buy-7adte006-atl...l2-shopping.htm (http://www.provantage.com/buy-7adte006-atlas-550-dual-eia-530-ussi-module-supports-nx-56-64-db25-port-adtran-500-series-4200754l2-shopping.htm) )

If you can get your local switch tech to break it up into BRIs, depending on whether you planned to go over 512Kbps you could simply use the Adtran ISU 512e IMUX(the "e" is for euro) ( http://www.adtran.com/static/ENTERPRISEPRO...S/1203086L1.htm (http://www.adtran.com/static/ENTERPRISEPRODUCTS/ISDN/ISDNACCESS/1203086L1.htm) ). Really easy to use and does the job well.

Could you be a bit more specific in what you're trying to do?

Yeah, If you can break it out into BRI's, the Adtran ISU 512 is a great device. They are the most reliable IMUX I have ever seen, and very easy to configure and operate....

The Atalas 550 will work great too, but it is quite expensive, and a bit harder to configure....

What is that you actually want to do?

If you provide us with a little more info about your setup and what you want to accomplish, maybe we can help you find the right products.

I figured from your post that you had a Tandberg MCU, wich only has PRI interface and want to connect it to a rs-449/rs-350 network??


Best regards

Welcome gbroo. I am assuming that you are trying to go secure if you wish to use RS449/530. If you are not going secure, what is the special situation which requires you to use RS449/530?

If are trying to go secure, and you are using a Tandberg MCU, the only real solution out there is using back to back Adtrans. This works, but it is not an easy setup.

An alternative to this would be to mix manufacturers and use something like Radvisions S40 serial gateway, connecting it to your dial isolators (if you need 366 dialing) and your encrytion device. You would then use the Tandberg MCU as an IP bridge (on a dedicated SECURE network of course).

Anpther alternative would be to wait until closer to the end of year. Tandberg has just come out with their MPS large capacity MCU. I understand that serial connectivity is in the works for the MPS, and may be available in the last quarter (I am hoping). This only works if you are looking to buy a new bridge and are not in a hurry.

If you can, try to give us a little more detail into what you are trying to do.

This can certainly be done. TANDBERG has an application note on this topic, please contact your TANDBERG representative. Or contact me offline, and can get the document to you.

Sean,

Is this the back to back Adtran solution, or is there another solution out there?

[sdevoy]

Guys,
How about using the Initia/Madge/Teleos box? www.initiainc.com
I still use it install it, support it......

Works fine.

Hi,

This solution utilizes an Adtran 880/890/550 to front end the MCU and present PRI to the MCU. This solution also works with TMS :-). It will work in most cases for Type 1 encryptors, but will not work in other cases. If you are looking for non encrypted RS449/V.35, the solution works quite well.

The Initia box, supports all protocols actively used for secure apps, globally, for some 8 years.
Does BRI to PRI for Brents, V.35/RS449/X.21 etc. Used successfully with the MGC and the MPI card.

sdevoy is correct in the use of the Initia box. For PRI T-1 you can use the Initia Access Switch 20 model #M20-0022. If you are using PRI E-1 then you will have to get the larger 60 model #M060-0038, but you will have to add the following cards to the 60 to make it work, QEIU card for E-1 connections, and the QRVX-4 card for the RS-449 connections.

All,
1st, thanks for your replies! Here's what I have, I have a Tandberg IP MCU that I am trying to connect via KIV, so the pieces in place are, Tandberg MCU-Adtran550-Pairgains(to change to a T1 interface) and then a DCCS......I have the dual USSI 530 (do I need the RS366) I have it IP MCU-Adtran-KIV-DCCS-other KIV- and then the hub.

Thanks again,
Greg

Sean,
I'd love to see the tandberg application?...

Thanks,
