Hello,

I have Ingenico 5100 terminals connection to AS5300 with mica modems.

When terminals are set for 2400 and I have
Code:
modemcap entry
POS_5100:MSC=&F&D2S0=0S15=0S21=0S22=0S23=0S24=0S29=4S30=2400S31=1200S64=6


Terminals connect and information is exchanged.

But if I set the terminals to 1200

And
Code:
modemcap entry
POS_5100:MSC=&F&D2S0=0S15=0S21=0S22=0S23=0S24=0S29=4S30=2400S31=1200S64=7

or
Code:
modemcap entry
POS_5100:MSC=&F&D2S0=0S15=0S21=0S22=0S23=0S24=0S29=4S30=2400S31=1200S64=8


They got disconnected after first packet is exchanged.

Any idea what to change?

If additional information is needed I'll provide it( if it is not
confidential for sure).

Thank you in advance.

I guess first of all, I would ask what different terminals you need to support,
and
how are they configured. Are some set for 2400 bps (V.22bis) and others for 1200
bps (Bell212a or V.22)?

Is it feasible to configure all terminals as desired? If so, then why not
configure
them all for V.22bis - which you say works fine - and be done with it?

Or must you support some terminals that are configured for V.22bis, and others
that
are configured for V.22/Bell212a?

In that case, you don't want to use S64 which sets a fixed modulation, and so
can't
possibly accommodate clients that are configured for different modulations.

We normally find configuring the MICA modems to automode for V.22bis (actually
V.23) and
below works well. Here is a typical configuration:

&f&d2s29=4ss53=0s15=0s22=0s23=0s24=0s0=0

If you should find that that a PoS call works well from one client but does not
from another
client, then here are the debugs that I would collect.

First, configure msec timestamps on your debugs, and "no logging console". You
might
want to log to a logging buffer. Also configure an ACL to match traffic to/from
your
application server. Also configure "service internal" (hidden global command).
Also
configure "modem call-record terse".

Also busy out all modems but one (if you can).

debug isdn q931 ! or debug cas
debug csm modem ! or debug modem csm, in some IOS
debug modem
debug modem mica tx s/p
debug modem mica rx s/p
debug ip tcp packet address <server-address>
debug ip packet detail dump <ACL> ! hidden command

Capture all of the debug output from a successful call. Then do the same for a
failed call.
Now compare and contrast the information from the two calls.

Have fun,

Aaron
