Modems & Mux

[IT Department_2]

Hi,

Please can anybody point my in the direction of documentation on how to install two modems for dial out onto a 32 Port Mux panel (Model J2096A) on a K370 server.

Any help will be greatly appreciated.

Andy.

You should be able to do so through SAM in either case.

sam-->peripheral devices-->Terminals and modem.

action menu --> add modem

When I try to add the modem, sam replies with :-

There are no avalible ports on the highlighted (selected) mux/serial device.

Sam also suuggests that my mux card may not be able to support modems, and I cannot find any documentation for the mux.

I do know that we currently dont use any mux ports and I can not see any configured in sam.

Any more ideas?

Thanks

Andy

Hi,
first you need to configure MUX to system(you need to have driver for MUX which can be downloadable).after configuring the mux you can attach modems configure and dial out/in

Hi Andy

Mux cards support modem or any other serial devices . We have modems installed on K Class server on the MUX CARD in our setup . Please follow the following :

1. First ensure that the MUX card is installed properly ie software wise , ie it should be sensed by the kernel while booting and you should be able to associate with each port a unique tty device.

2. Please create an entry in /etc/inittab similar to that for the console and enable getty for the that terminal on which you want to install the modem , genrally the first or the last port . Once you can enable getty then you can test the port by connecting it to a terminal and you will get a login if getty is running on that tty. Once you can login using that port you are all set to install modem on that port.

3. Disable getty on that port by changin respawn ( 2nd field ) to off and kill the getty , then go to /etc/uucp and edit Devices fiel to contain atleast the following two lines

Direct ttyXX - 9600 direct \D
ACU ttyXX - 9600 ps_mt1432_tone

and you are all set to go.

If the modem is now connected to ttyXX and there is a line coming to it you can TEST dial out you own extension or a local no using

cu -s9600 -l/dev/ttyXX < telNo>

all the best.
