Operational Statistics and Auto-
Reporting
Operational statistics provides the activity report for the MultiMux
network, and Auto-Reporting provides a means to report on these
statistics through the supervisory console on a set periodic time cycle.
Statistics such as receive-block errors pinpoint modem or line problems,
and flow control time totals indicate channel devices being set at
excessive speeds. Two simple commands are all that is necessary to
select statistical reporting and time cycle. If your command port is also
connected to a printer, the reports can provide an easy means of
generating data for better network management.
1.5.7
Parameter Memory
A nonvolatile memory for storing configurations and options means that
the MultiMux remains configured until you change it. Using this feature,
you can configure a MultiMux, turn it off, ship it and use it without having
to reconfigure it.
1.5.8
Channel Flexibility
The MultiMux permits a great deal of flexibility in configuring channel
parameters. You can mix up channel options, including speed, word
length, stop bits, parity, flow control, pacing methods, echoes and pass-
through characters. Channel control commands let you change single
channels, all channels or selected channels with a single command. By
using the downline loading capability or the command modem, channels
can be configured at the other end of the network.
1.5.9
Command Modem
The MultiMux can connect to a dial-up phone network through an
integral 2400/1200/300 bps V.22bis-compatible modem called the
"command modem". The command modem is an asynchronous modem
used for remote configuration of the mux. The command modem is not to
be confused with the "link modem", which is either an internal or external
synchronous or external asynchronous device handling the data
transfers over the composite link between two muxes.
By using the command modem, you get the equivalent of a remote
Command Port console. Your MultiMux can be dialed into from a remote
location for remote testing and configuration. The command modem will
automatically answer incoming calls.
