E&M Voice – Slot ss Port p Options (2 of 2)
Rx Gain (dB)
Possible Settings: –17.0, –16.5, –16.0, –15.5, –15.0 ..., 0.0, ..., +6.5, +7.0, +7.5
Default Setting: 0.0
Determines the receive path analog signal amplification on the E&M voice port in
decibels. This is the gain (increased signal level) or attenuation (decreased signal level)
applied to the signal before it is presented to the user’s analog equipment.
The range differs depending on the T1 NAM and E&M software revision, and the
hardware revision. Go to

Rx Gain (dB) only appears if Port Status is set to Enable.
–17.0 to +7.5 – Increases or decreases the signal level. The more positive the number,
the greater the signal level.
Tx Attenuation (dB)
Possible Settings: –17.0, –16.5, –16.0, –15.5, –15.0 ..., 0.0, ..., +6.5, +7.0, +7.5
Default Setting: 0.0
Determines the amount of attenuation, in dB, that the E&M voice receive port applies to
the analog signal presented by the user’s analog equipment transmit port. Positive TX
Attenuation settings reduce the level of the encoded analog signals sent towards the
telephone network, and negative settings will introduce gain. The proper setting of this
strap is crucial to ensuring compliance with Part 68, FCC Rules and Industry Canada’s
CS-03 Specification.

Trunk Cond in CGA
Possible Settings: Busy, Idle
Default Setting: Busy
Determines the trunk condition or state that the port is forced into as a result of the
Carrier Group Alarm (CGA).
Trunk Cond in CGA only appears if Port Status is set to Enable.
Busy – Forces the port to Busy during a CGA.
Idle – Forces the port to Idle during a CGA.
