threshold ranges from 0 to 200. Normally, the signal amplitude on the links 
without traffic is in the range of 2 to 5.

time-length: Silence duration for automatic on-hook. Upon expiration of this 
duration, the system goes on-hook automatically. It ranges from 2 to 7,200 
seconds.

Use the silence-th-span command to set the silence duration for automatic 
on-hook.

Use the undo silence-th-span command to restore the default.

By default, the silence threshold is 3 and the silence duration for automatic 
on-hook is 7,200 seconds (namely, 2 hours).

# Set the silence threshold to 20 and the silence duration to 10 seconds.

0: Sets the output gain of the subscriber line interface circuit (SLIC) chip to 0.8 dB.

1: Sets the output gain of the SLIC chip to 2.1 dB.

Use the slic-gain command to configure the output gain of the SLIC chip. The 
bottom layer tunes signal gain through the SLIC chip.

Use the undo slic-gain command to restore the default output gain.

By default, the output gain of the SLIC chip is 0 dB.

# Set SLIC-gain to 1 in analog E&M voice subscriber line view.
