Modem Configuration

There are also configuration options in the V42/MNP/Buffer branch of the 3800Plus modem which affect SDC efficiency.

(LAPM) Max Frame Size. Except in environments where line impairments are known to be unusually high, set this to the maximum (256).

Sync DTE CRC. If the CRC type of the DTE frame is the 16-bit CRC for HDLC frames as defined by ITU-T, set this to CRC16.

SDC Delay Min. If clamping of the receive clock (circuit 115) is accepted by your DTE, then set this to Rx_Clock.

Sync Flow Cntrl. The Tx_Clock selection is suitable for most synchronous DTEs. If your DTE interprets transmit clock clamping or a drop in CTS as a problem (resulting in an aborted frame), set Sync Flow Cntl to None. Selecting None should not be a problem if the entire acknowledgment window of DTE frames does not exceed 5 kilobytes, so that it can be buffered by the modem.
