DescriptionSetting
Attenuation is measured in decibels, and the lower the number, the
better the voice quality. Adjust the attenuation and input gain values
to achieve maximum voice quality.
The minimum value is –6, and the maximum value is 14.
Output Attenuation (dB)
This option sets the attenuation of the signal before it enters the line.
To reduce the line loss set the output level to 0, –7.5, or –15 dB.

Connection Settings
T1 PRI spans provide several options, depending on the carrier or
switch. Determine the switch to which you are connecting and the
preferred protocol.
Protocol Type
Show Advanced Settings/Hide Advanced Settings
Interface Settings
This setting specifies whether the gateway connects to a Network
device or to a User device.
Make sure that the two ends of the PRI connection use opposite
settings. For example, if you connect to a PBX and the PBX uses
User as its protocol side, select Network for this device. Typically,
use User for this option for central office connections.
