Emergency Call E-11
E-11 Emergency Call
General Description
This feature allows a user to make an EMERGENCY CALL by dialing a special telephone number (emergency
telephone number). Even if the calling station goes on-hook, the calling station is recalled and the speech path is
maintained until the emergency telephone goes on-hook. When a station dials the emergency telephone number, a
system message is printed out to report the EMERGENCY CALL.
Operating Procedure
The operation of EMERGENCY CALL is the same as STATION-TO-STATION CALL [S-11].
Service Conditions
1. This service feature is available when an emergency telephone number is dialed via STATION-TO-
STATION CALLING [S-11].
2. This service feature is also available when an emergency call is made via CALL FORWARDING - ALL
CALLS [C-5] or CALL FORWARDING - BUSY LINE [C-2].
3. Switch hook flash services, such as CONSULTATION HOLD - ALL CALLS [C-17], may be restricted.
4. Only the emergency telephone is allowed to disconnect from an emergency call. Upon disconnection, the
calling station will hear reorder tone.
5. This service feature is not available between emergency stations. When either of the emergency stations
goes on-hook, the other emergency station receives reorder tone, and CALL BACK [C-1] is not
performed.
6. When a station makes an EMERGENCY CALL by any method, other than STATION-TO-STATION
CALLING [S-11] (e.g., STATION-TO-STATION CALLING - OPERATOR ASSISTANCE [S-12],
OFF-HOOK ALARM [O-6], etc.), there is no system message printout, but CALL BACK [C-1] to the
calling station is performed.
7. When a D
term
is used for an EMERGENCY CALL, VOICE CALL [V-2] can be used.
8. An emergency telephone can assign CALL FORWARDING - BUSY LINE [C-2] or CALL
FORWARDING - ALL CALLS [C-5], but when transfer is made to other than an emergency station, this
service feature is not available.
9. An emergency station can assign CALL FORWARDING - DON'T ANSWER [C-3]. In this case, when a
call terminates to the emergency station, a system message printout is performed. When a call is
transferred by CALL FORWARDING - DON'T ANSWER [C-3], the situation regarding when the station
goes on-hook is as follows:
a.) If neither the calling station nor the transfer destination station is an emergency station, there is no
CALL BACK [C-1].
b.) If either the calling station or the transfer destination is an emergency station, CALL BACK [C-1]
is operative. (No printout is performed).
c.) If both the calling and destination stations are emergency stations, there is no CALL BACK [C-
1]. (No printout is performed).
10. When the emergency station is busy, the caller receives busy tone, and this service feature is not available.
11. The emergency station can be a member of a hunting group. If hunting results in transfer to a station other
than an emergency station, this service is not available.
12. The emergency station can be a member of a UCD [U-1] group. If a call is distributed to the emergency
station after queuing, system message printout is not performed.
