The options on the Management Channel Menu are documented in Table 3-6 below.
Management Channel Menu Commands
Configure Management Channel - TYPE returns this list of choices:
type (1) direct (2) modem (3) stat mux (4) auto (5) none (6) x.25 pad >
Selections 3 and 6 may be used only with Access Manager 2000 as the network management program.
Node Manager supports direct or modem connections to an NCC module.
Use this option to determine how long the NCC card will wait after an alarm has occurred before it attempts to report that alarm to the management PC.
This screen selects behavior for the Primary (U1) and Secondary (U2) communication paths back to the management PC.
If both primary and secondary paths are defined, the NCC will try first one number and then the other until a management PC is reached.
(1) direct —Select only if the NCC is co-located with the PC running AM2000 or Node Manager and it is directly connected via an RS-232 cable.
(2) modem —Select if the NCC has a modem connected. Use a Verilink part number 458-501771- 008 cable to make the connection from the MANAGEMENT PORT IN on the rear interface connector module to the DB-25 connector on your modem.
(3) stat mux —Select if you are using a Statistical Multiplexer. This selection tends to be very problematic, as stat muxes are not known for reliability.
auto —Do not select auto.
none —Select if there is no PC running AM2000, or
if you do not wish for this NCC card to initiate calls to the Network Manager.
(6) x.25 pad —Select if you are using an X.25 PAD. interval 0-59S or 1-59M or 1-24H >

Example—“15S” for fifteen seconds.
For each command, U1 or U2, the following prompt is returned:
use (1) none (2) send (3) backup > Select (1) to disable this function.
Select (2) to send according to the other options in this menu.
Select (3) if this is your backup method of reporting alarms.
B1 selects the baud rate for the primary path to a management PC.
The following prompt appears: rate (1) 1200 (2) 2400 (3) 4800 (4) 9600 >
B2 selects the baud rate for the secondary path to a management PC.
Choose the highest rate in bits per second that your communication path supports.
Selects the number of tries (attempts to connect to the network manager) for the primary (R1) and secondary (R2) paths to
