IVX C-Class with voice mail: Installation Manual Function 1: System parameters
D.5
Function 166: CO parameters
Field 1: CO-to-CO conference gain
Adjusts the volume level on CO lines when in a
conference call. Increasing this level to a high setting
can cause excessive noise or feedback on conference
calls. This is a threshold gain level. Doubling or
halving the current setting is in 6dB increments.
Range: 100–32767. Default: 2048.
Warning: Adjusting field 1 while calls are in progress may result in temporary loss of audio.
Field 2: CO playback gain
Adjusts the volume level the system uses to play back recordings, prompts or messages to a
CO line. If this value is set too low, callers into the system may not be able to hear the greeting
of a mailbox or the auto attendant when either answers the call. 6 = 0dB; going up or down from
there is in 3dB increments.
Range: 1–12. Default: 6.
Field 3: Trunk-to-trunk CO gain
Adjust this if callers in a trunk-to-trunk connection — either through the “reach-me” feature,
manual connection or auto attendant — are unable to hear or have excessive noise or
feedback. 10 = 0 dB; going up or down from there is in 3dB increments.
Range: 1–12. Default: 8.
Warning: Adjusting field 3 while calls are in progress may result in temporary loss of audio.
Field 4: Delay before connection “beep-beep”
Adjust this if connection tones are played either too soon or too late after the system answers a CO
or intercom call. Sets the amount of time before the connection “beep-beep” is started. Expressed in
1/100s of seconds.
Range: 10–100 (i.e., 100 ms to 1 second). Default: 20 (i.e., 200 ms).
Field 5: Caller ID gain
Adjust this level if Caller ID information isn’t being displayed. Setting this field tells the system
how much CID signal it needs to determine whether the signal is valid CID. This is a value set
in the DSP and is similar to the fax energy level (see Function 165, field 4, page D.4).
Range: 1–32767. Default: 20000.
Warning: Adjusting field 5 while calls are in progress may result in temporary loss of audio.
