Modifying an Analog
Terminal Port
You can modify the configuration of an Analog Terminal Card port or a
Single-Port ATA at any time.
To modify an analog device configuration:
1 In the NBX NetSet - Main Menu window, click
Device Configuration
. The
Device Configuration dialog box appears (Figure 49).
2 Click the ATA tab. The ATA dialog box appears (Figure 76). This dialog
box shows all ports on 4-Port Analog Terminal Cards and all Single-Port
Analog Terminal Adapters (ATAs).
3 Select the analog device that you want to modify.
Return busy tone when
device is in use Returns a busy tone to the caller if the telephone
attached to this ATC port or ATA is in use.
NOTES:
■
If you enable this check box and the user enables the
Do Not Disturb feature on the analog telephone,
callers hear a busy tone whether or not the telephone
is in use.
■
If you enable this check box and configure an Analog
Line Card port such that the ATA is the auto
extension, when an external call arrives on the Analog
Line Card port and rings directly on the ATA, the
caller hears Ring No Answer instead of a busy tone.
This is the way that the NBX system works; it cannot
seize the Analog Line Card port until the ringing
telephone is answered.
