Note 1:

Set the groove on the switch knob to the desired switch position.

Note 2:

When the power is on, flip the MB switch to ON (UP position) before plugging/unplugging the circuit

card.

Note 3:

The SW 1 is used to select the AP operating mode as shown below.

On line : Normal operating mode. The AP should be always in the “On line”, other than when you delete the AP

data.

Off line : The mode for AP data clearing by the command CMD100/CMD101.

Note 4:

The use of the external clock (from the distant end) or the internal clock is determined by the following

table:

Note 5:

When the DCE connected to the port does not provide a function to send the DSR signals, set the switch

to ON. In this case, the AP00 card can not recognize the actual state of the DCE, so that the call records

or system messages will not be stored in the memory buffer on the AP00 card even if the cable is discon-

nected from the DCE.

When the switch is set to OFF, the call records or system messages will be stored when the cable is dis-

connected, and will be sent when the cable is re-connected.
