Loop Start FXO Properties - Field Definitions

Loop Start Type

Specifies the signaling type for the Loop Start Type.

The options are as follows:

Basic

This type does not provide disconnect signal. Tone-based disconnect supervision should be used, which could take about 20 seconds.

Forward Disconnect

Disconnects the call based on battery removal received from the line. The duration is normally 800 ms and it can be configured.

Reverse Battery

The call is disconnected based on the tip and ring polarity reversal.

DTMF On Time

Specifies the duration, in milliseconds, that the tones are on.

DTMF Off Time

Specifies the duration, in milliseconds, of the pause between tones.

Dial Tone Detect

Specifies whether or not a dial tone must be detected before dialing out.

Mimimum Forward Disconnect Duration

Specifies the time which qualifies as a valid forward disconnect (battery removal). Valid only when Loop Start Type is set to "Forward Disconnect".

Silence Based Disconnect

Enables and disables the supervision that disconnects a call following silence for the length of time defined in the Silence Based Disconnect Timer field.

Silence is detected only on the audio stream coming into the FXO interface side of the call.

Silence Based Disconnect

Silence Level

The level below which line noise must remain to qualify for silence. This field is only visible when Silence Based Disconnect supervision is enabled.

Silence Based Disconnect Timer

Defines the duration of time, in seconds for silence based disconnect. This field is only visible when Silence Based Disconnect supervision is enabled.

Tone Based Disconnect

Enables and disables tone based disconnect supervision of the CAS line. This field is only visible when Loop Start Type is set to Basic.

Disconnect Tone Cadences Per Cycle

Defines the desired on/off cadence time in one cycle for disconnect tone detection. This field is only visible when Tone Based Disconnect is enabled.

Dial Delay (When Dial Tone Detection is disabled.)

Specifies the duration, in milliseconds, of the delay between the off-hook condition and sending digits.

Provide Tone With Answer

Specifies that, should an inbound FXO call fail before it connects, the Ribbon SBC 1000/2000 attempts to connect and play a fast busy tone for a period of time before disconnecting the call.
