BRMA Connection Problem

[jupiter919]

Dear All,

Can somebody experience when you dial-in to the BRMA via the RMA board it's hang in the RMA connection process? it can't see anything when the modem get connected.

After perform a reset on the RMA board it back to normal, is that due to the hardware problem?Can it's be avoid ?

The conection may hang by itself with no warning,it is the problem when it's urgent cases.

With RMA box you should check
- RMA version. Was latest SW downloaded to the board?
- modem. Is it Alcatel supplied Multitech or another vendor?
- modem settings?
- modem cable. Is it supplied with RMAB or "home-made"?

A several sites with RMA connections, latest SW downloaded, Multitech modems connected - working without any problems for some years.

I use this string with every multitech modem

AT&F0 – load factory defaults
AT$SB9600 - Serial Port Baud Rate
AT$MB9600 - Modem Baud Rate
AT$D1 - Dial stored number N0 when DTR goes high.
AT&E7 - Respond to and pass through XON/XOFF.
AT&R0 - Let CTS state follow RTS state when on line.
AT&E11 - Enable non-error correction mode flow control.
AT&Q1 - Standard AT responses with no modifiers.
AT&D0 - Modem ignores DTR signal.
ATQ1 - Disable result codes (quiet).
AT$D0 - Do not dial when DTR goes high.
ATE0 - Do not echo keyboard input to the terminal.
AT&W - Store current settings in NVRAM.
ATZ - Reset modem .

Or put it straight
AT&F0
AT$SB9600$MB9600$D1&E7&R0&E11&Q1&D0Q1$D0E0&WZ

How we can check the RMA board or BRMA box version?

Is that any way to check on this hardware and the software compatibility?

Currently system was running on R6.2 and using the Multitech modem with model MT5634ZBA.The problem come from the RMA board or the modem?

If there are some configuration need to apply, please advice.Thank you.

We had some issues with one similar connection, but we discovered that it was caused by a single laptop modem from one of my colleagues. Try to use other modem and see if it still fails.

Regards.
