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.
