Digital E&M voice subscriber line view

received idle: Indicates the receive idle signal of digital E&M signaling.

received seize: Indicates the receive seized signal of digital E&M signaling.

transmit idle: Indicates the transmit idle signal of digital E&M signaling.

transmit seize: Indicates the transmit seized signal of digital E&M signaling.

ABCD: Default ABCD bit pattern during transmission, with each bit taking the 
value of 0 or 1.

Use the signal-value command to configure the ABCD bit patterns of idle 
receive, receive seized, idle transmit, and transmit seized signals on the digital 
E&M voice subscriber line.

Use the undo signal-value command to restore the defaults.

By default, the ABCD bit patterns of the receive idle signal and the transmit idle 
signal are 1101, and the ABCD bit patterns of the receive seized signal and the 
transmit seized signal are 0101. After changing the ABCD bit pattern of a digital 
E&M signal, you must shut down the digital E&M subscriber line with the 
shutdown command and then bring the line up with the undo shutdown 
command. Otherwise, the voice subscriber line cannot work normally.

subscriber line 1/0:0.
