Digital Data Calls
An analog multiline telephone user selects the lines to be answered by
the device connected to a General Purpose Adapter (GPA) by
programming each line for Immediate or Delay Ring. The lines not to be
answered are programmed for No Ring. If the user wants the device to
answer only inside calls, all personal lines must be programmed for No
Ring.
The system does not automatically select outside line, SA, ICOM, or
Cover buttons programmed for No Ring, even when Ringing/Idle Line
Preference is turned on. The user must select the button manually to
answer a call. (The green LED flashes when the call arrives; when the
user presses the button, the red LED turns on.)
The Delay Ring option can be used as an alternative to the LS-ID Delay
option to delay ringing at automatically answering adjuncts so that
Caller ID information is received. LS-ID Delay delays ringing at all
extensions in the system, while Delay Ring delays ringing only at the
station programmed for it.
Delay Ring timing starts when LS-ID Delay ends.
Primary Cover, Secondary Cover, and Group Cover buttons can be
programmed for Immediate Ring, Delay Ring, or No Ring.
Calls received on line buttons programmed for No Ring are not sent to
coverage.
If an Individual or Group Coverage receiver is on a call when a
coverage call is received, the receiver hears an abbreviated ring (if
Abbreviated Ring is enabled).
Calls received on a Primary Cover, Secondary Cover, or Group Cover
button ring with the receiver's (not the sender's) personalized ringing
pattern.
In addition to its primary function, the delay ring interval provides a
delay before calls go to Group Coverage (in addition to the coverage
delay interval), when the sender also has Individual Coverage and a
receiver is available.
Personalized Ringing has no effect on calls to a terminal adapter or
desktop video system.
Terminal adapters follow programmed ring options, and should be set
to Immediate Ring.
desktop video systems are not affected by ring options.
