Tandberg 880 mxp dialing issues

[buchu70]

Maybe someone has a answer for this one. My organization just purchased a large quanity of 880 MXP's and upon setting one up the other day we discovered an issue with placing calls at rates lower than 384. We are pulling network off of a private network using Teleos 200's and 60's with V.35/RS-366 (QRVX) network, extended with Eastern Research line drivers.

The 880 will rcv a call at any rate from 2x to as high a bonded call we want to make. The issue is when dialing out, even when changing the default call rate to say 128, the 880 will still connect at 384? The same happens with 2 channel (2x64 or 2x56).

Running F3.1 code on the 880 MXP.

Has anyone run into this??

** I know the bonding code this code uses is h0 and not bonding 1 setup. Could this be the issue. If so, is there an API command to disable or modify this??? I couldn't find one **

Thanks again.

Thanks for any input...

Not quite sure what you are asking but H0 service is a single 384kbps channel and not 6B (6 channels using bonding).

Are you connected to an IMUX? I bet you are not using ISDN in the 880, but in fact connected to an IMUX. If so, you need to pass the dial strings to the MUX to dial the correct rate.

Any call type below a 384 call outbound from the 880 (single b ch, 2 b chs and bonded rates) will all automatically jump up to 384 even when I set an other than 384 rate for the default call speed. When I dial for example a 128 bonded call and look on my Madge Teleos 200, on initial connection to the Madge from the 880, i see 6 b chs inbound on the Madge. This is the same for even a single b ch dial out. When you look at the call stats through a telnet session on the 880, its bonding type even when dialing only a single b ch is h0 (and i know h0 is a 384 rate minimum call type).

This is the issue I'm running. I'm using a Net 1 cable 111833, V.35/RS-366 to interface to a VSU-3566 hub extender and into a Madge 200 QRVX/V.35 port on a private network.

See.. like I said.. you are using an IMUX, not the ISDN of the codec.

Are you dialing the proper suffix strings to dial the Madge? The speed setting of the codec itself means nothing.. its the Madge who decides the speed of the call.. and you tell the Madge which speed to dial by dialing suffixes on the number to dial. like 13344444*6*64*8

Are you doing this?

The codec tells the Madge what speed to dial and * codes do not work also...ie:1234567*64*2*8 will dial a 384 call instead of 128

It sounds as if the 880 is not passing the suffix to the IMUX. The 880 should allow you to add the suffix information somewhere in the setup. I have not worked with the 880 yet but I will see what I can find out.

Just to clarify, I can place calls outbound at any rate of 384 or above. I can rcv calls at ANY rate. Just when dialing outbound and trying to connect at rates lower than 384, the 880 automatically sends 6 b channels and connects at 384. It does this even when the default call speeds are changed or the dial out speed is lowered.

Is the 880 MXP only capable of doing a 384 call outbound?

[flyfish]

I can't comment on the 880 as I work mostly with the switching equipment.

When you place the calls at speeds higher than 384, are you using a call suffix, and have you tried dialing at lower speeds from the Madge directly? This should help to point you in the right direction.

Is this F3 software? We have found an issue in F3 software where the suffix is stripped. This does not happen in F2. This will be addressed in the next version of software.

No, I am not using a suffix when dialing 384 or above. The ISDN network I'm using to test out the 880 came off a fully working Tandberg 6000 using the same serial (v.35/rs-366) connection, that has no issue dialing with or without suffixes at any rate.

Yes, this is F3.1 version software.

[trapehzoid]

even still.. you must dial the suffix.. the codec speed you select in the codec means NOTHING.

Sounds like a problem with F3 that you can't dial the suffix right.. but once that is fixed, you must still dial the suffixes..

The madge has a default speed for the port, that's why you get 384kbs all the time.

No the Madge doesn't have a default speed on the port. I can dial from 56k to PRI on the serial port connection to the Madge. I will see about downgrading the code and let everyone know the results though.

Last time I'm saying this.. YES IT DOES. Unless you specify via the suffixes the speed and type of call, the port will connect at the default rate defined in the madge profile. This is how the serial ports on Madge devices work.

They are RS-366 controlled dialing ports.. you MUST specify the the call profile to use via the dial string.. otherwise the IMUX has no idea what type of call you are trying to make and has no choice but to use the default configured for the port.

The 880 doesn't set those suffixes automatically.. you must type them in. This is how madge devices have been since the dawn of time (and that's probably when your madges were setup!)

Off he goes on one again. Man if you carry on like this you really are going to be very ill at a young age...

I program the Madge and it doesn't have a default speed rate set up on it but thanks for your input anyways. If you had read Les's post earlier you would've seen there is an issue with suffix command on the version code I'm running.

ONCE AGAIN... I'll just drop the codec back a version of code if I can and let all know the results.

I am pretty sure you have to specify a default call rate in the Madge. Whether you have or not, its there.

Tried to upload a snapshot of the Madge screen, but can't get the upload to work.

Sorry, you must have the super-special version of Madge software that doesn't have the feature every other copy does. Its the default number of channels setting.

And if you UNDERSTOOD what I said even without the issue Sean mentioned you STILL must dial the suffix strings. Your posts talk about setting the speed in the codec, THAT WILL DO NOTHING. That is the point you keep missing. Downgrade the software, and unless you dial the suffixes as instructed, you will still not connect at the speeds you want. Sean said the issue is the suffixes are stripped, not that they aren't required.

Obviously you inherieted this setup. Which just about every Madge setup is.. there is not a whole lot of people out there that actually understand it to properly set it up.. most people just copy 'what is working' without understanding it.

ONCE AGAIN... I'll just drop the codec back a version of code if I can and let all know the results.

The answer will be still be waiting for you when you get back. Downgrade, dial the proper suffixes and stop playing with the codec call rate settings.

[buchu70]

Sorry to inform you... but, downgraded the 880MXP and preset dialing speeds work fine now, no suffix required. Oh well, atleast its working.

Congrads.. you have the only codec in the world that can pass commands to a Madge IMUX port through magic. The tandberg can't send the suffixes automatically. You must be dialing via directories or something that have the suffixes included. Your dial speed setting in the codec do not do anything to the RS-366 dialing string. They've only built that functionality in for Adtran IMUXs. When in a RS-366 mode, the call speed menu doesn't do anything of value, unless you have a Adtran IMUX connected to the codec.

Whatever works for you
