Basic Calling Operation
The Teltone TLE provides dial tone (Normal – default), or Ringdown (Hotline), or a quiet
battery feed (Silent), when a device goes off-hook and draws sufficient loop current. When
dialing is detected, DTMF or Pulse (aka Rotary dialing), dial tone stops. If an invalid
sequence is dialed, the TLE will issue an Invalid Number Response of SIT + Audio
(default), SIT repeating, Busy, Reorder, Ringback, Silence, or Audio. If a valid number is
dialed, a Hunt Mode of Ring All (default), Ring 1st match, Ring 1st available, or Ring next,
is invoked. Caller ID information is sent to the Called Party, along with Ringing, and
Ringback tone is sent to the Calling Party. When the called line answers, a connection is
established between the two parties.
During an existing call, another party may go off-hook and dial a number that matches one
of the connected parties. If so, then a SAS (Call Waiting tone) + CAS (Caller ID tone) is
issued to the called party. If the called party has a Caller ID box or phone that supports
SCWID (aka Caller ID in Call Waiting), then the Caller ID information will be issued by the
TLE. If the called party does not answer the waiting call, a repeat of the Call Waiting tone
occurs ten seconds after the first. During an existing call, either party may wish to
Transfer/Conference another party. To accomplish this, the originating party must
generate a hook flash, after which the TLE will return a Confirmation Dial Tone, and the
originating party will dial the number of a third party. After connecting to the third party, all
three are brought together with another hook flash. Conference operation is dependent
upon the setting of the Conference Type in the Miscellaneous Screen.
The end of a call uses Calling Party Control. If the Called Party hangs up, the connection
may be re-established if they go off-hook before the Forced Disconnect Timer expires. If
the Calling Party goes on-hook, or if the Forced Disconnect Timer expires, then a Forced
Disconnect signal, a break in the loop current, is sent to the remaining party if they are off-
hook. After a Forced Disconnect signal is sent, and the party remains off-hook, then
Disconnect Treatment is invoked. The options include Dial Tone (default), Busy, Reorder,
Silence, or an Audio message.
