V.42/MNP/Buffer Configuration Options for SDC

Sync Comp Mode: DirectMode

Nxt DirectMode HDLC/SDLC

This configuration option only appears if Async/Sync Mode is configured for Sync.

Synchronous Compression Mode. Enables and disables synchronous data compression.

DirectMode ± Disables the Synchronous Data Compression mode.

HDLC/SDLC ± Enables the Synchronous Data Compression mode

The AT command for Sync Comp Mode is #SCn. See Table 3, page 9.

SDC Negotiation: LAPM_Buffer

Nxt LAPM_Buffer LAPM_Discon

This configuration option only appears when the Async/Sync Mode configuration option is set to Sync and Sync Comp Mode configuration option is not set to DirectMode.

Synchronous Data Compression Negotiation. Determines the type of negotiation used when the modem attempts to connect using SDC. See Table 5, page 15.

Link Access Procedure for Modems or Buffer ± The modem attempts to establish an SDC connection. If the remote modem has SDC capability, then the connection is established with SDC active. If the remote synchronous modem does not have SDC capability, then the local connection is made in Buffer mode.

Link Access Procedure for Modems or Disconnect ± The modem attempts to establish an SDC connection. If the remote modem has SDC capability, then the connection is established with SDC active. If the remote modem does not have SDC capability, then no connection occurs and the modem generates a disconnect.

The AT command for SDC Negotiation is S28=n. See Table 4, page 10.

SDC Idle Fill: Flag_Fill

Nxt Flag_Fill Mark_Fill

This configuration option only appears when the Async/Sync Mode configuration option is set to Sync and Sync Comp Mode configuration option is not set to DirectMode.

Synchronous Data Compression Idle Fill. Determines whether the modem uses an HDLC flag or mark to fill the time between DTE frame transfers.

Flag_Fill ± Causes the modem to fill the time between DTE frame transfers with HDLC flags. Mark_Fill ± Causes the modem to fill the time between DTE frame transfers with marks. The AT command for SDC Idle Fill is S29=n. See Table 4, page 10.

SDC BitEncoding: NRZ

Nxt NRZ NRZI

This configuration option only appears when the Async/Sync Mode configuration option is set to Sync and Sync Comp Mode configuration option is not set to DirectMode.

Synchronous Data Compression Bit Encoding. Determines the type of bit encoding scheme (NRZ or NRZI) the modem uses when transmitting synchronous DTE data.

NRZ ± Causes the modem to use the standard Non Return to Zero bit encoding scheme.

NRZI ± Causes the modem to use the Non Return to Zero Inverted bit encoding scheme.

The AT command for SDC Bit Encoding is S31=n. See Table 4, page 11.
