hi
i have a problems with two nm-16am module in a cisco 3725
1/ it can only be dialed by a phone line witch is configured in pos as
pulse line

2/ i can connect only in V.23 protocol not i V.34 or V.90 protocols

Doesn't matter whether the originate modem uses pulses or DTMF when
dialing into the NM-16AM. The signaling method is a private matter between
the originate modem and the switch on the other end of its POTS line.

NM-AM AT docs: http://www.cisco.com/univercd/cc/td/...e/analogat.htm

I will assume that your want your V.23 calls to use 1200 bps in the answer->originate
direction and 75 bps in the originate->answer direction. So you might try a modemcap
like this:

&fb0%m0\n0%b1200%f2

&f - reset to factory defaults
b0 - ITU not Bell for low bit rate modulations
%m0 - disable V.34 and above
\n0 - normal mode (no EC)
%b1200 - max DCE rate 1200 bps
%f2 - V.23 transmit 1200 bps, receive 75 bps


For fancier PoS knobs, see

Right, PoS applications almost never do PPP.

You will probably use a configuration like this:

line <begin> <end>
modem dialin
modem autoconfigure type XXX
autocommand telnet 1.2.3.4 /stream /quiet 4444

where 1.2.3.4 is the IP address of your PoS application server and 4444 is the TCP port
on which it listens.
