Ericsson LBI-39224 manual Output Signal Level dBm

LBI-39224

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.

NOTE

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.
