Dte Interface - Singleport Mode - Paradyne COMSPHERE 3920Plus Technical Reference Manual

DTE Interface — Singleport Mode
The DTE Interface configuration options contain EIA-232-D (ITU-T V.24) and asynchronous
character format information essential for maintaining a connection and for transmitting data
between the DTE and the modem.
Table 5-7 shows each DTE Interface configuration option as it appears on the LCD, with the Sync
Leased 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. Factory default settings are listed in
Appendix F,
DTE Interface Configuration Options — Singleport Mode A
Async/Sync Mode: Sync
Nxt Sync Async
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 to Sync, then the modem operates in Async
mode when offline.
For Async Dial, Async Leased and UNIX Dial, Async is the factory default.
The AT commands for Async Mode are &M0 or &Q0.
The AT commands for Sync Mode are &M1, &M2, &M3, &M5, or &Q1, &Q2, &Q3, &Q5.
Sync DTE Rate: 128000
Nxt 128000 115200 112000 96000 76800 72000 64000 57600 56000 48000 38400 28800 19200 14400

This configuration option does not appear when:
• Async/Sync Mode configuration option is set to Async.
• Sync Comp Mode configuration option is set to DirectMode.
• Tx Clock Source and Bakup_TXClk_Src configuration options are set to External when the Dual_Leased_Ln
configuration option is set to Enable.
• Tx Clock Source configuration option is set to External and the Dual_Leased_Ln configuration option is set to
Disable.
• The Synchronous Data Compression feature is disabled.
Synchronous DTE Data Rate. Identifies the synchronous DTE's operating rate to the modem. Data rates from
128,000 bps to 1200 bps are supported.
The AT command is S-Register S30 = n, where n is:
0 = 115,200 9 =
1 = 76,800 10 =
2 = 57,600 11 = 128,000
3 = 38,400 12 = 112,000
4 = 28,800 13 = 96,000
5 = 19,200 14 = 72,000
6 = 14,400 15 = 64,000
7 = 9,600 16 = 56,000
8 = 4,800 17 = 48,000
