Telephone Line Emulator User’s Manual
40-400-00020, Rev. M 16
Second Cadence on or off time may be set from 0 mS to 5000 mS in 5 mS increments, or
may be set to 0 if only the First Cadence values are to be utilized.
If the Second Cadence values are 0, the unit will repeat with the First Cadence values.
If the Second Cadence values are programmed, the unit will repeat after going through all
four time values.
Call Waiting
The Call Waiting signal (a.k.a. SAS Tone, Subscriber Alerting Sequence) is an indication
that there is a calling party waiting for the called party to become available. The calling
party hears normal ringing and the called party hears a Call Waiting Tone that is repeated
once, 10 seconds after the first occurrence. The called party answers a Call Waiting by
either generating a FLASH, which places the existing caller on hold, or by hanging up on
the existing caller, after which the telephone will begin to ring again with the waiting caller.
In some Central Offices, a waiting caller is announced with a Normal single tone if the call
is local, and a Distinctive two tone sequence if the caller is calling from long distance.
Call Waiting With Caller ID Enabled (SCWID or CIDCW)
SCWID (Spontaneous Call Waiting with Caller ID) also known as CIDCW (Caller ID in Call
Waiting) is a function that sends the FSK data (Caller ID) after a Call Waiting Tone. This
data transmission burst is typically sent to a specially configured telephone or an adjunct
device that mutes the line to the local caller for the duration of the FSK burst. The format
of the message is always multiple message format, that is, the Name and Number are
sent to the called party. This feature is invoked whenever a third party places a call to an
existing call, if Caller ID is enabled and Cancel Call Waiting has not been enabled. When
a third party is calling, the called line will be momentarily isolated and will hear a Call
Waiting Tone (SAS tone), followed by a CAS tone to alert the Caller ID phone or adjunct.
If the Caller ID phone or adjunct issues a DTMF “D” (from non-ADSI CPE) or a DTMF “A”
(from ADSI CPE) acknowledgement tone, the FSK sequence is sent down the line for
Caller Identification. The called party may then ignore the Call Waiting, or generate a
flash to place the first caller on hold, and answer the Call Waiting. If the Called Party
ignores the first Call Waiting alerting sequence, it will be repeated once, ten seconds later.
If the called party answers the Call Waiting, they are allowed to alternate between callers
using the flash function. If one party hangs up, the remaining parties are automatically
connected.
Call Waiting with Caller ID Disabled
A user may want to have the TLE generate just the Call Waiting Tone (SAS tone) without
Caller ID or CAS tone. To have the TLE perform in this manner, go to the Caller ID
Screen and disable Caller ID for the line in use.
Cancel Call Waiting
The Call Waiting tone may be disabled on a per-call basis by dialing ∗70 or 70#, TLE
Response - Confirmation Dial Tone. (See Dial Tone screen.) Call Waiting will be reset
and enabled after the line is placed on-hook.
