Feature description
With the Dial Pulse/Dual Tone Multifrequency Conversion feature, Dial
Pulse (DP) signals from analog (500/2500 type) telephones, Dial Pulse (DP)
TIE lines, Meridian 1 proprietary telephones, or Attendant Consoles are
automatically converted to Dual-tone Multifrequency (DTMF) signals for
transmission over trunks equipped for Dual-tone Multifrequency (DTMF)
service. Dual-tone Multifrequency (DTMF) signals from single-line 2500
telephones are automatically converted for transmission over rotary-dial-only
trunks, such as TIE lines. This eliminates the need for duplicate dials.
DTMF calling allows the use of 2500 telephones, equipped with push-button
dials, to transmit digits through audible tones to the Meridian 1 equipment.
This feature provides the ability to use any combination of telephones.
However, 2500 telephones cannot use DTMF to control dictation equipment
when the dictation trunk is specified as Dial Pulse (DP).
