Installation

SW2-1 FSK Mode

SW2-1 ON = ITU-T V.23 mode

OFF = Bell 202 mode

The modem has two FSK modes:

™Bell 202, which supports data rates from 0 to 1800 bps

™ITU-T V.23, which supports data rates from 0 to 1200 bps

SW2-1 configures the modem for either of these FSK modes. Setting SW2-1 to ON selects ITU-T V.23 mode. In this mode, the modem complies with ITU-T (CCITT) recommendation V.23 with the following parameters:

™Mode 2 modulation only

™No backward channel

™No provisions for disablement of echo suppressors

™DTR (circuit 108) is ignored

Setting SW2-1 OFF selects Bell 202 mode.

SW2-2 Receiver Squelch (FSK Mode 2-Wire Half-Duplex Only)

SW2-2 ON = 8ms for Bell 202, 150ms for ITU-T V.23 OFF = 0ms

SW2-2 configures the turnaround squelch delay and is valid when the following are active:

™FSK mode (SW3-1 ON)

™2-wire half-duplex operation (SW3-7 ON)

Setting this switch to OFF configures the modem to enable its receiver immediately after the Request To Send (RTS) signal is turned off. When this switch is set to OFF and the modem is configured for 2-
