SDI Communication with both cores 1

[ddickenson]

I've been going through the first real ground up installation and commissioning of a Meridian 1 (outside the classroom) and I can't seem to get the TTY communicating with SDI paddleboard. I can hook up to each core and talk there and I've tried every combination I know to get tty0 or 1 running. They say enabled and when I connect serial to them it shows "connected" in procomm but I get nothing.

I have disabled and re-enabled the ttys, even outed and rebuilt...

My ADAN printout for tty0 is below. It shows up as QSDI but as far as I can tell it's a SDI2 and I can't seem to change that. Isn't that paddleboard automatically dnum 0 and 1?

The paddleboard is set to 9600, DTE I believe but I've tried both.

ADAN TTY 0
CTYP QSDI
GRP 0
DNUM 0
DES MAINT
FLOW NO
USER MTC SCH MCT CSC
XSM NO
TTYLOG 2
BANR NO


Any ideas?

I'm guessing you are a cs1000M with CPPIV CPU in a UEM module? I'm saying that because these are no longer sold as new systems - just upgrades.

If this is the case - get out you book - Circuit Card Reference Avaya Communication Server 1000 - 7.5 copy is NN43001-311

go to this section and verify your switch settings for port numbers and baud /DTE/DCE - Chapter 24: NT8D41BA Quad Serial Data Interface Paddle Board - assuming you have the 4port paddle board. If you have the 2 port, GHTROUT just posted info on that.

Second, pinout for paddle board is not standard. You need to use the Nortel cable for paddle board or make your own.

Connects the NT8D41 SDI Paddleboard to DTE or DCE through the I/O panel.

You are correct that it is not a new system. It's more or less and upgrade but a forklift type upgrade. I have a release 23 Option 81c and this is CS1000M-MG Succession 4.5 that I'm going to cutover to. I had already verified settings in every nortel pub I could find including Circuit Card Reference but it's almost certainly the pinout. I didn't realize it was different and was trying to use a standard cable. If I'm going to make one does it just need to be a crossover type cable, like leave one end of a standard cable alone and change the other? I have the nortel cable on the old switch, but for now I still need it there.

Also as this is the older Motorola processors and full length core slots (CP4 68060E) it has the SDI2 NT8D41AA on the backplane.

If you are using a cable assembly that works on the core, then it cannot work on the paddle.

Thanks guys, I'm sure that's what my problem was! Kinda irritating that I went through all that just to find out I was using the wrong cable though!

 

[GHTROUT]

I find a good cable with the right connector on each end, then I cut it in the middle and splice it until it works

How about for the Sys Monitor? I have a small ribbon cable that comes from the larger ribbon cable that connects direct to the system monitor devices in the pedestal and it comes to a db25. I wanted to attach that to the second SDI port, do I need a special cable between those two or just a db25->db9 adapter?

 

[ddickenson]

UPDATE: I found the proper cable in a box of random cables I had and tried it but still no joy. I then outed tty 0-3 and started over calling the CTYP: SDI2 as it should be instead of qsdi like it was auto populating (I suppose since I had other TTY defined on what it thought was the same board) and after that... still no joy. I get a "connected" message from the term emulator like it sees something on the other end but if I hit enter or any keys I don't get anything on the screen.

Here is programming of a working paddle board with the System Monitor on the first port. If I were to guess what is wrong in your case, it would be: speed, or wiring, or straight vs. null adapter.

Have you verified the dip switches on the paddle board for the correct DNUM, baud rate, etc.?

 

[ddickenson]

Yes, I have triple checked the switch settings on the board, tried different boards, different cables, different programming... still nothing...

 

[Reusser]

If you have the right cable - NT8D93 SDI I/O to DTE/DCE Cable
and correct switch settings - TTY DNUM, Baud rate, DCE/DTE setting

possible ports are hung and possible 2 ways to clear
1 - reseat paddle board
be sure to disable all TTY ports
Disable toggle switch on card
reseat card - careful to pull out straight

2 - ini pbx

I figured out what the deal was with this. After finding the correct cable (thanks to yall) I realized that the DB25->DB9 adapter I was using was shorting pins 1,2 and the shield together... After getting another one of those I was golden. Thanks for all the help!
