External Alerts
Description
External Alerts provide standard station ringing at locations away from the called stations.
This feature can be used to activate an external alerting device such as a bell.
External Alerts supports the Trunk-Answer-from-Any-Station (TAAS) form of Night Service.
The feature can be used in conjunction with voice terminals located in noisy environments
and large areas such as warehouses, etc. The alerting device is activated whenever the
associated station is alerted.
A Supplemental Alert Adapter installed on a hybrid station allows the terminal user to
transfer incoming ringing to an alerting device located in some remote area. When the user
goes to the area, the alerting device rings for incoming calls to the user’s normal station.
Considerations
External Alerting enhances user ability to recognize incoming calls. Noisy environments, large
areas, and outside locations are candidates for external alerting devices.
Interactions
The following features interact with External Alerts.
Manual Signaling: Manual Signaling will not activate an external alerting device.
Night Service:
When the system is in Trunk-Answer-from-Any-Station (TAAS) Night Service
mode, an incoming attendant-seeking call will activate the Night Service alerting device.
Power Failure Transfer: When the system
alerting devices are disabled.
Administration Requirements
Special Feature Port:
● An external alert operating as the
assignment on a ZTN78 Tip Ring
is in the power failure transfer mode, the external
endpoint device on a station line requires a port
Line or TN742 Analog Line CP. (Specify special
feature port type = 253.) An external alerting device controlled from a Supplemental
Alert Adapter operates on the same line as the associated terminal and requires no
additional port assignment.
● Specify the PDC of the associated station (or 0 if alert is used with TAAS Night
Service).
