UDS V3229 Modem Features

  • Fully compatible with V.32 bis and V.42 bis standards
  • Maximum data throughput of 57600 bps using V.42 bis data compression or 28800 bps using MNP level 5 data compression
  • Automatically adjusts data rate to 14400,12000,9600,7200,4800 2400, 1200, or 300 bps (CCITT V.32 bis, V.32, V.22 bis or Bell 103)
  • Full-duplex, asynchronous or synchronous operation over dialup lines and 2- or 4-wire leased lines

The UDS Motorola V.3229 modem is a high-speed data modern ideally suited for applications that require accurate, reliable operation with a high data throughput. Fully compatible with V32 bis for reliable 14400 bps operation, the application of V42 data data compression can increase data throughput to a maximum rate of 57600 bps while MNP level 5 can increase throughput to 28800 bps. For accurate data transmission over even the worst telephone lines, the V.3229 incorporates V.42 LAPM and MNP Net 2 through 4 error control as well as echo canceling, automatic adaptive line equalizing, and trellis coding techniques.

The UDS Motorola V3229 modem full-duplex, asynchronous or synchronous data at 14400, 12000, 9600, 7200, 4800, 2400, or 1200 bps, asynchronous-only data at 300 bps over dialup lines and full-duplex, asynchronous or synchronous data at 14400, 12000, 9600, 7200, and 4800 bps on leased lines. With automatic adjustment of data rate and modulation scheme to the remote modem, the UDS Motorola V3229 modem is compatible with most V32 bis, V32, V22 bis and Bell 103 modems.

The UDS Motorola V.3229 modem autodialer is compatible with the industry standard Hayes AT command set for asynchronous applications and with CCITT V.25 bis for synchronous applications.

Dial back-up from leased to dial-up line allows the modem to operate without interruption if the leased line fails. The line is monitored at timed intervals and leased line operation is resumed automatically when possible.

In a network of UDS V3229 modem supporting remote configuration, the feature eliminates the need for trained operators at remote sites. With just a phone call and a password, the user can view the current option settings of a remote modem and modify the configuration as required.

For easy option selection and status monitoring, the UDS Motorola V.3229 modem features 32-character liquid crystal display with three control pushbuttons and six LED indicators.

The UDS Motorola V3229 modem is available both as a standalone unit and as a card that plugs into the Universal Data Shelf
