Managing Remote Modems in an AccessWay Enclosure

Managing remote modems in an AccessWay enclosure requires the following setup and operation.

Managing Remote Modems

Step	Stage
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.
3.	Ensure that the secondary channel is enabled (AT*NE1).
4.	Set the remote master modem’s Pass Through (AT *NP) parameter
	to the appropriate option (NP options are described below).
5.	Issue NM commands to the other Accessway modems.

Pass Through Parameter (AT*NP)

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.
