Modem Configuration
There are two primary ways to use the modems; RAS and Modem Sharing.
Prior to software release version 1.03, the ports were configured for either RAS
or modem sharing, for which they were then dedicated to just that role. Now,
with software release version 1.03, the ports can be configured for both roles,
alleviating the need for administrator intervention when either role is desired.
The Modem Configuration fields define specific parameters per port. The
number of ports shown depends on the specific model of MultiAccess, POTS
modems 1 and 2 for the MA220, POTS modem 1 thru 4 if the model is the
MA420 or POTS modem 1 thru 8 if the model is the MA820.
The Modem Setup screen defines the Modem Sharing behavior and general
modem parameters, Country Code and number of rings before auto answer.
The TCP port, socket, number used by Telnet to access the modem is
dependent on how the Modem Sharing Pool option is used. If this option is set
to "pool", port 6000 is used. All POTS modem ports set to pool, 6000, must
have the same exact Modem Sharing option, with or without authentication, etc.
When a Telnet client on the LAN opens a connection to 6000, it is given the
lowest number POTS modem port that is not in use.
If this Modem Sharing Pool option is set to "non-pool", then a specific port
7000+ number is sequentially associated to each POTS modem, POTS modem
1 is assigned 7000, POTS modem 2 is assigned 7001 and so on incrementally
through POTS modem 8 with 7007 for a MA820 unit.
Modem Sharing with authentication means a login prompt will be issued to the
socket when it is opened. Who (what) ever opened the socket must provide
appropriate credentials before access is given to the modem. When access is
granted to the modem, an "ok" response message will be issued.
When Modem Sharing with Radius Authentication is selected, the Radius server
that will be used is defined in the Authentication menu.
When Modem Sharing with Local Authentication is selected, credentials (users)
shown in the Local Users menu are to be used.
When Modem Sharing with RAW is selected – support for RFC 2217 (com port
control via Telnet) will be disabled.
