Sliding Cursor Procedure
To accommodate easy and uncomplicated redialling (LNR) behind a PABX, a sliding
cursor protocol is implemented. If new entries match the previous RAM contents,
pressing the
LNR
key will dial out the remaining digits.
If there is an error in matching, the LNR will be inhibited until next on-hook, and the RAM
will contain the new number.
Tone Generator
The tone generator incorporates the DTMF tones and 3 basic frequencies for the tone
ringer.
DTMF Tones
The DTMF Tone Generator creates 12 Tones in compliance with CCITT Recommenda-
tion Q23. Signal levels are altered by Mask Option. High group frequencies have a level
2.6dB higher than those of the Low Group.
Details of the DTMF Tones are:
Low group
Digit 1-2-3
697Hz
(Error = -.074%)
Digit 4-5-6
770Hz
(Error = -.679%
Digit 7-8-9
852Hz
(Error = -.621%)
Digit *-0-#
941Hz
(Error = +.139%)
High group
Digit 1-4-7-*
1209Hz
Digit 2-5-8-0
1336 Hz
Digit 3-6-9-#
1477Hz
(Error = +.533%)
(Error = +.176%)
(Error = -.141%)
Errors are calculated with reference to a base clock of 3.58MHz and at ambient
temperature of 24°C. They exclude tolerance errors in the base frequency.
