When FXO port answers the call, FXS may send a Polarity Reversal. If this
interval is shorter than the value of "Polarity on Answer Delay", the Polarity
Reversal will be ignored. Otherwise, the FXO will on-hook to disconnect the
call. The default setting is 600ms.
This is the periodic time (in ms) that the UCM6510 will use to check on a
voltage drop in the line. The default setting is 200. Valid range is 50 to 3000.
Configure the ring timeout (in ms). Trunk (FXO) devices must have a
timeout to determine if there was a hang up before the line is answered.
This value can be used to configure how long it takes before the UCM6510
considers a non-ringing line with hang up activity. Default setting is 8000.
Configure the RX gain for the receiving channel of analog FXO port. The
valid range is from -12.0 (Db) to + 12.0 (Db). The default setting is 0.
Configure the TX gain for the transmitting channel of analog FXO port. The
valid range is from -12.0 (Db) to + 12.0 (Db). The default setting is 0.
Configure to enable CallerID detection. The default setting is "Yes".
