Management
Channel Options
The Management Channel Menu is used to configure the DB-9
Management Port In interface. It may support an optional dial-up
modem or a direct connection to either Access Manager 2000 or
Node Manager.
For the NCC series, the Node Manager application supports direct
or modem connections only.
Access Manager 2000 supports direct or modem connections, and
also supports connection through a stat-mux (Statistical
Multiplexer) or an X.25 PAD (Packet Assembler and Disassembler).
If a network manager program is being used, it will typically setup
all of the values in this entire submenu. In that case these routines
should not be used to make changes. Generally the user will
observe values in these screens or make changes only when
troubleshooting an inability to connect to the network manager.
