Managing Remote Access Concentrators Using Annex Manager

Chapter 8    Configuring Modems

8-12

The

Modems List

 box includes all internal modems for the ISDN Primary

Rate RACs you selected. You can select one or more RACs. This box
includes:

•

The

Annex

 name.

•

The

Modem #

 for each internal modem.

•

The current

 Status

 for each modem:

–

Available

 indicates that the modem is in working order and is

not being used.

–

Busy

 indicates that the modem is set to this status to make it

unavailable.

–

Used

 indicates that the modem is handling a call.

–

Failed

 indicates that the modem is not working.

The

Modem Status

 button allows you to change the status of an internal

modem. You can select:

•

Available

 to make a modem available when its current status is

Busy

 or

Failed

. You cannot choose

Available

 for modems that are

in use.

•

Busy

to prevent a RAC from selecting a modem that may not be

operating properly. If you select

Busy

 for a modem with a

Used

status, the

Busy

 status does not take effect until the current call

terminates.

When you change a modem status, the

Modem List

 box reflects your

changes immediately.
