86 Strata CTX General Description 10/04
The telephone main Msg light indicates a message is waiting for the telephone [PDN]. Up to four
[PhDNs] per telephone can also have individual MW LEDs assigned to flexible buttons.
Stutter Dial Tone
Stutter dial tone is also used to indicate a message is waiting or your telephone is in the DND
mode. When a station user goes off-hook, two different available stuttered dial tones indicate
whether a Message Waiting (MW) or DND condition exists. The MW-stutter dial tone indicates a
message is waiting for the station. DND-stutter dial tone indicates DND is set at the station. (DND
provides a fast busy tone burst as stutter dial tone.) If both conditions exist simultaneously, the
MW-stutter dial tone has priority. This is very valuable to station users that do not have a MW
Light Emitting Diode (LED) or
DND button LED on their telephone. (See Table 38 on page 110
for details of each type of stutter dial tone.) With Release 1.3 and higher, users can disable (in
programming) stutter dial tone for message waiting and when in the DND mode. If stutter dial tone
is disabled, they will hear normal dial tone when you go off hook.
Microphone (External Unit)
System Availability: All systems
An external microphone (RFDM) can be connected to the DKT2020-FDSP digital telephone
enhancing “full-duplex” operation by virtue of the “superdirectional” characteristic of the
microphone. When this option is on, the internal microphone is disabled on all but Voice First
Handsfree Answerback calls and OCA calls. The external microphone is powered by the DKT and
does not need to be turned off when not in use.
Music-on-hold
System Availability: All systems
Music-on-hold can be derived from a customer-supplied radio, tape player, tuner, CD player or
other device to provide music or announcements to parties on hold on CO lines or on [DNs]. With
the Strata CTX, you can have up to 15 MOH/BGM sources. Each CO line group and each DID/
DNIS number may be assigned a specific MOH source. Stations and network Tie lines can also
share a unique MOH source.
Multiple Call/Delayed Ringing
System Availability: All systems
With Strata CTX Release 1.3 and higher, you can assign Delayed Ringing to voice mail and auto
attendants. This feature can also be used to ring multiple (25 max.) telephones immediately or with
a delay by dialing a group pilot number. Each group member can have Immediate, Delayed Ring 1
or Delayed Ring 2. Delayed Ring times are adjustable (1~180 seconds) for each Multiple Call
Group. Multiple calls to digital telephone is supported; however, delayed ring to digital telephones
is not supported as of this printing.
