Output Signal Level (dBm)
This setting establishes the signal level in dBm (600-ohm impedance;
0 dBm = 1 milliwatt) sent out by the selected channel's line output. The
setting specifies the voice peak (test tone) level sent out by the channel.
The valid range is -25.0 dBm to +13.0 dBm in 0.5 dBm increments.
Select the required value from the drop-down list box.. Output Signal
Level default = 0 dBm.
Channel Signaling
For a VMIM interface module, this setting does not specify or influence
control signaling sent out by the respective CI Board's channel to a
conventional base station. All utilized channels should be set to
"NONE." CI Board-related Secur-It/function/hold tone level settings
necessary for tone-controlled conventional base stations are
accomplished by the 2175 Hz Hold Tone Level (dBm) setting in the
Tone Controlled Station State Table Mapping dialog box, which is
a sub-box of the Conventional Channel Configuration dialog box.
Secure Tone
This setting is not used for a VMIM. The 2175 Hz Hold Tone is set
from the Conventional Channel Configuration dialog box.
The secure tone and transmit hold tone are set on a per Audio
Board basis. For example, setting channel 2 equal to 5 dBm
will simultaneously set channels 1, 3 and 4 equal to 5 dBm.
Bus/Slot Equipped
All utilized channels within an interface module must be allocated a
time slot on the CEC/IMC TDM network. Allocate a time slot to the
selected channel by setting Bus/Slot Equipped to "YES." A channel
will not route audio correctly if is not allocated a time slot. Set all
unused channels to "NO," (the default setting).
Notch Filter
Do not enable the notch filter on any utilized channel for a VMIM.
Enter (type) "NO" in the text box.
