C-150 Call Block
Service Conditions (cont’d)
12. Only one Restriction Number (a maximum of 32 digits) can be registered per station. A maximum of 32
digit Restriction Number can be assigned up to five numbers per D
term
and one number per analog station.
A maximum of 511 stations can be registered per 1 IMG.
13. The Restriction Number cannot be confirmed from single line telephones after registration.
14. To assign the Restriction Number, it is available to register the latest incoming call number if the call is
received in the following cases:
a.) Station-to-Station Calling,
b.) A call is terminated via the trunk which received the calling number
If the station cannot receive the number of the last incoming call, the latest call that meets the
conditions above is registered as the Restriction Number. Thus, it can’t be available to assign the
latest calling number as the Restriction Number immediately after system initialization.
15. When assigning the latest incoming call as the Restriction Number using feature key from an idle station
or a ringing station, the latest calling number to the MY LINE is registered as the Restriction Number (then
the feature key on the controlling terminal lights red). Thus, on a D
term
whose PRIME LINE is not MY
LINE, the displayed number is not registered when a call is terminated at PRIME LINE. The latest calling
number terminating at MY LINE is registered in place of the displayed number.
16. When a call is transferred, the telephone number of the intermediate station is to be registered as the latest
incoming call number even if that station releases the connection. Only the first terminating number is to
be the Restriction Number.
17. This service is activated corresponding to each line. In case a D
term
containing some lines, the Restriction
Number is effective only for the line to be registered the number.
18. When confirming the registered Restriction Number, the number registered on MY LINE is displayed for
5 seconds on the LCD.
19. This service is available only when the predetermined Restriction Number and the receiving Physical
Station Number/telephone number or the calling number are exactly the same.
20. In this service, a telephone number is used to recognize the station incoming call, however, a Physical
Station Number is used for the station which is not assigned the telephone number.
21. When an incoming call via No. 7 CCIS is terminated, a maximum 16-digit calling number (Route Data:
CI=1) can be received. If the telephone number is more than 17 digits, the incoming call is not restricted.
22. There is no need to register ACC for a C.O. trunk call (ex. “9”) when assigning Restriction Number by
dialing operation.
23. In case Restriction Numbers are registered up to the maximum number, a previous Restriction Number
must be cancelled before setting the new Restriction Number on a station. (It is impossible to overwrite
the Restriction Number.)
24. Sending Tone, which is used when originating a call from a station on which Call Block is set, can be
selected on the system base (ASYD SYS 1, Index 322, Bit 5).
25. When initialization of the Circuit Card is activated, the Restriction Number already registered is not
cleared.
26. When system initialization is activated, the Restriction Number already registered is not cleared.
However, when initialization of system data loading is activated, the loaded number (former Restriction
Number), not the latest Restriction Number, is to be registered as new Restriction Number.
27. The Assigned Restriction can be confirmed by the DCBD command.
28. This service is activated against each line. When a D
term
is used, Restriction Numbers can be registered at
multiple lines. However, to clear the Restriction Number using the “*” or “#” key is effective for only the
number registered to MY LINE.
