Manual Dialing when the Remote Modem Is Configured for Manual Answer

If you are originating a call using a telephone and the remote modem is configured for Manual Answer, perform the following procedure.

Once the remote telephone is answered by the remote user, you must both decide when to place the modems into Data mode. You must both select Tlk/Data at approximately the same time to begin the handshaking sequence.

If the handshake is successful, the modems are in Data mode and OnLine appears on the LCD.

NOTE

If the remote modem is not a 3800 Series modem, then the remote user must consult that modem's operator's manual to perform a similar operation.

Once the modems are online, status messages listed in Table 4-4 in Chapter 4 appear on the Top-Level display.

It is not necessary to specify an originating or answering modem when dialing via the DCP because the answering modem remembers that it received a ring voltage and will automatically default to Answer mode.
