Configuring a Network Modem
A modem/router, when controlled by the VMS as part of a communications
network, has its performance automatically controlled as VMS monitors the
modem/router’s role and performance in the network. VMS then commands the
modem to modify its configuration, as needed, to optimize network perfor-
mance.
In addition, the modem portion of each modem/router in a network can be
controlled manually. Using the CDM-570/570L as an example, the listing in
table 4-1 is typical of the information available in a modem/router’s user docu-
mentation.
Each modem/router will have its own unique user interface and connection
methods. Check the modem’s documentation for details.
Note: Not all modem functions may be controlled by the VMS. Refer to the
device’s user documentation for instructions for using functions not avail-
able through the VMS.
