Figure 10. Call Waiting Screen
The Call Waiting signal has several variables, including: Disabled, Single Tone or Dual
Tone, Type of Call Waiting Signal, and Cadence.
Call Waiting Tone Levels and Frequencies
Call Waiting Tones may be single or dual frequencies with individually adjustable
amplitudes. With a selection of Single Tone the system will only generate the first tone.
With a selection of Tone 1 + Tone 2 the system will generate both tones with the specified
frequencies and amplitudes. Purchase of the International Module adds the selection of
Tone 1 x Tone 2. The system will generate Tone 1 modulation by Tone 2. In this
implementation only the fundamental and upper side tone are generated, both at the
amplitude programmed for Tone 1.
For each tone, the frequency range may be set from 10 Hz to 1800 Hz in 1 Hz increments.
Output Level may be set from -6 dBm to -60 dBm per tone in 1 dB increments.
Call Waiting Type
Call Waiting Type may be programmed for each Line. Options are Disabled, Normal,
and Normal & Distinctive.
Call Waiting Cadence
Two Cadences are available: Normal and Distinctive.
Both Cadence on times may be set from 0 mS to 1500 mS in 5 mS increments.
Cadence off time may be set from 0 mS to 1500 mS in 5 mS increments.
Leading Blank, or the delay before the call waiting tone is sent, may be set from 5 to 100
mS off in 5 mS increments. (Default = 50 mS.)
