10. SIGNALING AND SUPERVISION
TABLE 10-l
DIAL PULSE LIMITS
General
This Part details the technical parameters of the PBX with re-
10.01
gards to signaling and supervisory condition.
Dial Pulse and DTMF Tone Data
10.02 The PBX is capable of accepting and repeating signals from
telephone sets which have the parameters shown in Table 10-1,
Dial Pulse Limits, and Table 10-2, DTMF Tone Limits.
10.03 When any of the frequencies shown in Table 10-2 are present
at the system input, any other single frequency (200-3400 Hz)
should be a minimum of 40 dB below the former. However, DTMF
pulses are registered, in the presence of precise dial tone at a level of
-10 dBm.
