Centrex Switchhook Flash
Because Autodial Tandem Transfer uses Centrex Switchhook Flash (THF), it
is affected by any modification to the THF enhancement feature.
Conference
The ATX feature is blocked during Conference and No Hold Conference
calls.
Digit Display
Digit Display allows the automatic display of information relevant to normal
call processing if the telephones have display capability and the Class of
Service is ADD or DDS. When the THF key is pressed, the display gets
cleared, and pressing the ADL key causes the ADL digits to be displayed.
However, no ADL digits will be displayed if no Tone and Digit Switch
(TDS)/XCT is available to generate the Dual-tone Multifrequency (DTMF)
tones for the ADL digits.
End-to-End Signaling
EES is used to send the Automatic Dialing (ADL) digits to the Public
Exchange/Central Office (CO). With Autodial Tandem Transfer (ATX),
the 911 agent can use the ADL key or manually dial the digits, or use a
combination of both methods, to dial the third party’s number. The ADL key
can be pre-programmed with a prefix and the remaining digits can be dialed
manually to distinguish between different numbers. When you combine
manual dialing with the ADL key, if EEST = YES and DTMF = YES in LD
15, you hear the DTMF feedback tone as a result of manual dialing and a
single feedback tone as a result of pressing the ADL key. To get uniform
feedback tone when using the ADL key along with manual dialing, set the
DTMF prompt to NO in LD 15.
Improved End-to-End Signaling is used to send the pre-programmed ADL
digits to the CO. With the ATX feature, a 911 Agent can use the ADL key,
or manually dialed digits, or a combination of both to dial the third party’s
number. It is recommended to set the DTMF prompt to NO (EES – LD
15) to get uniform feed back tone (single feed back tone) when using the
ADL key along with manual dialing.
Last Number Redial
Normally, when the ADL key is pressed during the dialing stage, the ADL
number will replace the Last Number Redial number. In the ATX feature,
however, when the ADL key is used during the established stage, the ADL
digits will not substitute the Last Number Redial number.
