WARNING
If CPC time is set to less than 250 ms, disconnection can occur on polarity reversal/answer
supervision on outgoing calls in some countries.
Loop Current Checking
The iQ6 periodically checks each analog line port for loop current. When current is detected, the single dot
icon appears on status screens and the line is ready. This process is called Loop Check. Yes is the default.
When you are using “ground start” lines, this should be set to No. Note: The iQ6 does not support outbound
dialing on ground start lines. However, setting Loop Check to No will allow incoming calls to work normally.
Note
Ground Start analog lines are not fully supported. Only Incoming calls are allowed.
You can, however, take advantage of this to get a feature that might be useful:
preventing outgoing calls.
Enable Auto Call Drop
Calls can be automatically disconnected when the far end hangs-up. Most USA-style Telco lines provide
a momentary loop drop for this purpose, but non-USA lines and most PBXs provide a tone signal (Call
Progress Tone - Disconnect) instead. The iQ6 can respond to one, both, or neither of these signals. The type
of tone signal detected for CPTD is determined by the POTS Country setting.
ISDN Interface Settings
ISDN Protocol
Selects the ISDN protocol, which must correspond to the ISDN circuits you are using. It will apply to all
ISDN lines.
There are a number of choices, but the most common are described below.
For Europe and many other parts of the world
- ETS 300. This is the very common Euro-ISDN, according to the ETS 300 standard.
For USA & Canada and a few other parts of the world
