Managing Remote Modems in an AccessWay Enclosure
Managing remote modems in an AccessWay enclosure requires the
following setup and operation.
Managing Remote Modems
Step
1. Ensure that a modem card is installed in Slot 9, position B
(Figure 1-11). It is known as the master, and it transfers network-
management commands to and from other modems in its enclosure
through the enclosure backplane. Note: a master cannot transfer
commands to and from modems in other local enclosures.
2. Make a leased-line or dial-line connection from a local modem to a
remote master modem.
Ensure that the secondary channel is enabled (AT
3.
4. Set the remote master modem's Pass Through (AT
to the appropriate option (NP options are described below).
5. Issue NM commands to the other Accessway modems.
Pass Through Parameter (AT
Pass Through options affect only dial connections. Pass Through
options determine:
• How and whether a local modem passes network management
commands to a remote modem
• How and whether a remote master modem passes network
management commands to other modems connected to it by:
— Cables between their NM IN and NM OUT ports
— A shared backplane in an AccessWay enclosure
The Pass Through parameter uses the in-band secondary channel to pass
network-management commands. Secondary-channel transmission is
not disruptive of main channel data.
