Configuring the Modem

When the modem is configured for V.23 operation (SW2-1 ON), the RTS-CTS delay is fixed at 33 ms.

SW2-6



FSK CD Delay (Bell 202 Mode Only)

SW2-6 ON = 23ms

OFF = 6ms

SW2-6 selects the FSK CD delay and is valid when Bell 202 mode is active (SW2-1 OFF). Setting SW2-6 ON

configures the modem to turn on CD 23 milliseconds after it detects a valid carrier signal. Setting this switch to OFF

configures the modem to turn on CD 6 milliseconds after it detects a valid carrier signal.

This switch setting is deactivated when the modem is configured for V.23 mode (SW2-1 ON) and a delay of 18

milliseconds is used instead.

SW2-7



Remote Loopback

SW2-7 ON = Loopback enabled

OFF = Loopback disabled

During instances of channel noise, the modem may mistaken a received preamble as a request to go into remote

digital loopback. Setting SW2-7 to OFF prevents the modem from participating in a remote digital loopback with

another modem. SW2-7 does not prevent the modem from sending a remote digital loopback request to a remote

modem.

SW2-8

−

Reserved (Test Only)

SW2-8 Must be OFF

SW2-8 must be in the OFF position for normal operation.
