Examing FXO Ports on Cisco ISR (VIC2-4FXO)

[david.lumbers]

Hi,

I can't remember so I want to ask which command is showing us FXO port's idle line voltage? How can I see the line connected or not with FXO interface from CLI.

Best regards,

David

Hi,

The show voice port summary command can help you.

R1#show voice port summary
PORT	CH	SIG-TYPE	ADMIN	OPER	IN STATUS	OUT STATUS	EC
===============	==	============	=====	====	========	========	==
0/0/0	--	fxo-ls	up	dorm	idle	on-hook	y
0/0/1	--	fxo-ls	up	dorm	idle	on-hook	y
0/0/2	--	fxo-ls	up	dorm	idle	on-hook	y
0/0/3	--	fxo-ls	up	dorm	idle	on-hook	y
2/0/0	--	fxs-ls	up	dorm	on-hook	idle	y
2/0/1	--	fxs-ls	up	dorm	on-hook	idle	y
2/1/0	--	e&m-wnk	up	dorm	idle	on-hook	y
2/1/0	--	e&m-wnk	up	dorm	idle	on-hook	y

I' m sorry but there is a misunderstanding here. I want to know, how can I see the TELCO line cable (RJ11) is connected with VIC2-4FXO line card when it's inactive from Cisco ISR CLI. I suppose the command what you send is only showing line values when the line is active.

Best regards,

David.
