ARGUS 3u plus/3u NT

8.1.2 POTS monitor

Essentially, the POTS (analog) monitor provides a high

impedance tap that does not influence the interface. You

can listen to the line with the integrated handset without

having the ARGUS send on or otherwise influence the

interface.

The ARGUS displays the

voltage level on the line when

it is "on hook“ (not busy).

Start monitoring

The ARGUS displays the

voltage (when "off hook"), the

number of the caller (when

CLIP is supported) and the

DTMF characters dialed by

both telephone subscribers

and the SMSs received

(optional).

Any received DTMF-

characters will be appended

to the line, which will shift left

for each character once it is full.

An incoming call will be signalled acoustically.
