Chapter 3 – Configure your MultiAccess
Time Configuration
1. In the MultiAccess Administration screen, go to the Time Configuration fields.
2. In the Time Server window, select from the three time server URLs. The default is time.nist.gov. The
Time Server is a substitute for a real-time clock in the MultiAccess.
If you would like to add your own time server, you can enter the URL or IP address of your time
server in the Add Time Server window.
3. In the Request Interval window, select the Days, Hours, and Minutes that the MultiAccess will
update its clock from the time server.
4. If you are in daylight savings time, check the Use Daylight Savings Time (DST) box.
5. In the Time Zone, Date Format, and Time Format windows, choose the options for your time zone.
6. Click the update button to change to your new parameters.
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, both roles are automatically enabled,
alleviating the need for administrator intervention when either role is desired.
The Modem Configuration fields allow you to define the parameters per port. The number of ports shown
depends on the specific model of MultiAccess, POTS modem 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 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 the Modem Sharing Pool option is set to "non-pool", then a specific 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.
