Configuration Tables

The modem's configuration options are arranged into eight groups based upon functionality: DTE

Interface (Table 8-1), DTE Dialer (Table 8-2), Line Dialer (Table 8-3), Dial Line (Table 8-4), Leased Line (Table 8-5), V.42/MNP/Buffer (Table 8-6), Tests (Table 8-7), and Misc (Table 8-8).

Throughout these tables, two selections frequently appear on the LCD: Enable and Disable. Unless otherwise stated, Enable selects a configuration option and makes it available for use; Disable makes a configuration option unavailable for use.

The remainder of this chapter discusses each configuration options group in detail, listing factory defaults, definitions, and AT command equivalents.

DTE Interface

The DTE Interface configuration options contain RS-232D (CCITT V.24) and asynchronous character format information essential for maintaining a connection and for transmitting data between the DTE and the modem.

Table 8-1 shows each DTE Interface configuration option as it appears on the LCD, with the Async Dial factory default setting (the default value if the modem is just being installed) shown following the colon (:) on the first line and with all available selections listed on the second line. Following this is a description of the configuration option, a description of the available selections, and any equivalent AT commands.

DTE Interface Configuration Options

Async/Sync Mode: Async

Nxt Async Sync

Asynchronous/Synchronous Mode. Determines whether the modem operates in Asynchronous mode or Synchronous mode. If the AT command set is enabled and this configuration option is set for Sync, then the modem operates in Async mode when offline.

For Async Dial and UNIX Dial, Async is the factory default. For Sync Dial and Sync Leased, Sync is the factory default.

AT command equivalents are &Mn and &Qn.

*Async DTE Rate:19200

Nxt 19200 115200 76800 57600 38400 14400 12000 9600 7200 4800 2400 1200 0±300

Asynchronous DTE Data Rate. Identifies the asynchronous DTE's operating rate to the modem. Data rates from 115,200 bps to 300 bps are supported.

To originate calls in 76,800 bps Sun Workstationr environments, use either DCP dialing, DTR dialing, or handset dialing. The modem does not support AT command dialing at this data rate.

To prevent losing data in 115,200 bps applications, a 16650 (or faster) UART on the PC's serial port is required, as well as a communications package which can take advantage of its 16-byte buffer. In addition, a 386 25-MHz (or faster) PC is required, and the RS-232 cable must be 6 feet or less to minimize capacitance.

NOTE: This configuration option is ignored in Async Direct mode and synchronous mode since the DTE rate always equals the VF rate.

The factory default is 19200 bps.

There is no AT command equivalent; AT prefix determines Async DTE Rate.

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