200 ICP 2

This is a fresh bulliten from mitel, released today! The cable info doesn't seem too clear though.


Article Title
Modem setup for SX200 ICP - Cabling and AT command set. Publish Date
Apr-20-2005


Body/Solutions
The following cabling and AT command set are to be used when connecting an AT command compatible modem to the SX200 ICP. Our examples use USR 33.6 and V.92 modems. If you have a different modem that supports the AT command set, consult your modem manufacturer to determine the correct equivalent settings for that modem.

Step 1: Verify your USR 33.6 or V.92 modem register bits are setup as follows. To determine the modem's current settings, connect the modem to a laptop at 9600 8N1 with a straight through cable. Before powering on the modem, set dip switches 1,3 and 8 down, the rest of them up.

Step 2: To alter the register, type the command prefix at, followed by the register letter and desired value. For example, if the modem had register f set to 0, register x set to 4 and register &N set to 0, those registers need to change.
You can change each register individually:
atf1 <enter>
atx1 <enter>
at&n6 <enter>

or combine the necessary changes into one command:

atf1x1&n6 <enter>

Then the changes must be saved to the modem's memory:

at&w0 <enter>

Then type ati4 again to confirm the changes were made.
When confirmed, power off the modem, set switches 1 and 4 down, the rest of them up.

Step 3: Verify the cable to be used between the ICP and the modem. Two cables have been tested with the USR 33.6 and V.92 modems.

Cable Number 1: Cable Number 2:

DB 9 DB25 DB9 DB25

1 -------------------- 20 1 open
2 -------------------- 2 2 --------- 2
3 -------------------- 3 3 --------- 3
4 -------------------- 6,8 4 open
5 -------------------- 7 5 --------- 7
6 -------------------- 20 6 open
7 -------------------- 5 7 open
8 -------------------- 4 8 open
9 -------------------- open 9 open


The cables may be purchased as a single cable, created using store bought components, or self made as long as the end result is one of the above cables. For example, during testing, cable 1 was made of 3 store bought components. A db25 to db25 straight through cable, a db25 to db25 null adapter, and a db 9 to db 25 convertor.

Thanx mitel man we'll give it a try

I agree, the "cable" information is confusing. I'll look at the TSB and see if I can figure out what they're trying to say. Meanwhile, here's what we use:

MITEL set up for a USRobotics SPortster:
Modem Dipswitch settings (D=down, U=up)
1 = D
2 = D
3 = U
4 = D
5 = U
6 = U
7 = U
8 = U
Send the following Modem setup commands (once):
AT&F1 (calls up factory defaults)
AT&R1 (Ignore RTS)
AT&W0 (write/save it to NVRAM)

Now POWER-CYCLE the modem.

Enter the command ATI4 (that's "eye-four" not "14") to confirm proper setup.

Cable connections

DB25 DB9
2 2
3 3
7 5
5 7&4 (tie together)

(other pins/wires not used)

OK, I have some clarification on the cable confusion. In the TSB Mitel says, in part:

Step 3: Verify the cable to be used between the ICP and the modem. Two cables have been tested with the USR 33.6 and V.92 modems.

Cable Number 1: Cable Number 2:

DB 9 DB25 DB9 DB25

1 -------------------- 20 1 open
2 -------------------- 2 2 --------- 2
3 -------------------- 3 3 --------- 3
4 -------------------- 6,8 4 open
5 -------------------- 7 5 --------- 7
6 -------------------- 20 6 open
7 -------------------- 5 7 open
8 -------------------- 4 8 open
9 -------------------- open 9 open

What they're trying to tell us, in their own stumblefooted way is that two seperate cables have been tested to work but their lousy wordprocessor cannot format the page correctly.

Therefore, the following two cables work equally well:

DB9 ------>> DB25
1.............20
2..............2
3..............3
4..............6 & 8
5..............7
6.............20
7..............5
8..............4
9..............not used (no connection)

Works just as well as:

DB9 ------->> DB25
1..............not used (no connection)
2..............2
3..............3
4..............not used (no connection)
5..............7
6..............not used (no connection)
7..............not used (no connection)
8..............not used (no connection)
9..............not used (no connection)
