Function
The parameter states functions for different types of telephones or equipment that can be connected to an analog extension line circuit.
Bearer services for originating extension. This category is introduced to be able to allow two different bearer services, 3.1 kHz (useful when it is connected to a fax machine) or speech (default value).
Global no-progress tone for voice mail systems. It is used to select the global tone to use for the main no-progress cases: global dial tone (default value) or global interception tone. If the enhanced global tone option is not selected, it has no effect.
Caller identity presentation. It is used to activate the display of the caller identity on the types of telephones supporting this function. The caller identities of calling internal parties or parties via trunk or tie lines with number/name information transmission capability, will be displayed.
Polarity reversal. It is used to indicate to the extension that some event has happened in the progress of the call.
Enhanced global tone. The normal tones defined for the market are replaced by standard tones: standard global busy, ringback, noprogress and reorder tones. This may be required when a voice system is connected via analog extension line circuits.
Message waiting lamp. The telephone may have a dedicated lamp for message waiting indications. This lamp can be handled with voltage ramp or polarity reversal.
Call metering. Used to send 12 kHz or 16 kHz metering pulses to the extension according to the charging information received from the public network. This function is available for extensions when the call is made via ISDN trunks.
Inquiry. The use of inquiry can be restricted for certain extensions, no matter if it is initiated with hook flash, R-button, or earth button.
Noprogress indication. In error situations or when the other party clears the call different types of release indications or release signals can be selected for certain extensions such as paging and answering machines or Release Link Trunks.
Ringing signal. Both private and public calls to the extension can be indicated with internal ringing signal.
Type of signalling. Selects the type of signalling for sending the caller identity information.
Type of standard. Selects the type of standard to follow for FSK signalling.
Data transmission mode. Selects the caller identity data transmission mode when FSK signalling following ETSI is used.
Example
- The instrument category shall be:
Bearer service is 3.1 kHz = 1.
Caller identity presentation = 8.
Polarity reversal at B-answer = 3.
Normal tone = 0.
Message waiting lamp with voltage ramp = 0.
No call metering pulses = 0
The extension is not allowed to initiate inquiry = 1.
The extension is not allowed to initiate inquiry = 1.
Special no progress tone shall be used = 2.
Internal ring signal for external calls = 8.
Type of signalling = 0.
Type of standard = 2.
Data transmission mode = 0.
The hexadecimal sum of these categories for D1 is (1+8) = 9.
The hexadecimal sum of these categories for D3 is (0+0+0) = 0.
The hexadecimal sum of these categories for D4 is (1 + 2 + 8) = B.
The hexadecimal sum of these categories for D5 is (0 + 2) = 2.
