NC-AD300E Manual- 31 -Device will automatically recognize the line module at startup. If automatically recognizefailed,select the right line type base on this selection menu.If you are using a Force type, such as"FXS (forced)", it will not automatic recognize.After completion of editing, write ROM, restart the device to take effect.5.2.5.2 Analog Signal SetAdjust the analog signal parameters can make equipment better adapt to the environment andstableoperation. Goes to "SLC" in the Index area see the basic parameters as below:In the part of SignalDetectedCycles: HangUp = 30 ms means that hook after 300 milliseconds theline will be in the status of hanging up, pickup=50 ms means that after 50 ms that pick up the linestatus will be pick up. Flash=70ms means if the hook up time is larger than 70ms and less than300ms, the hook acation will cause the line status change to flash.Ring=4500ms means the ringing period is 4500 ms.FxoReceivCidIdleOver: When call is incoming through analog trunk (FXO), the device will detect itand receive Caller ID (CID). If the FXO ringing time over this time interval (which has become anormal ringing) will be judged to have been finish the CID receiving. If less than or equal to 200milliseconds will not detected FSK CID. Recommended value: 2000. fill the value of 0 will be thedefault values: 2200.FxoReceiveCidRingTimes: If after FXO rings this value times but CID have not yet received,
