DDSMR-64  DDS/MR64
Motorola UDS Telenetics DDSMR64

The Motorola UDS Telenetics DDSMR64 combines the functions of a DSU and CSU into a single unit. It operates in either point-to-point or multipoint applications, transmitting synchronous data at rates from 2400 bps to 64,000 bps clear channel, and asynchronous data from 2400 bps to 57,600 bps. The DDSMR64 complies with Bell publications 62310 and 41450 and is directly compatible with Bell 500 series DSU and CSU equipment.

UDS DDSMR64 High speed asynchronous capability operating a 38,400 and 57,600 bps on 56K lines allows direct connection of high speed asynchronous DTEs to DDS lines. Switchable EIA-232 and CCITT V.35 interface allows a single model to provide both interfaces. Provides highly reliable digital performance on both conventional DDS networks or as a limited distance modem, so that one model can be used for either interstate or interoffice communications. Operates at all DDS line rates from 2400 bps to 64,000 bps including 19,200 bps to accommodate a wide range of DTE devices. Automatic line equalization compensates for distortion and attenuation caused by line length without user adjustment. Convenient front panel LCD control allows viewing current configuration and status without causing an interruption of dam. Saves operating configuration to nonvolatile memory, eliminating having to setup every time the unit is turned on.

Two flexible versions to choose from: DDS/MR64 standalone. DDS/MR64 RM16M nest card for use in Data Shelf enclosures Easy migration path to higher speeds by supporting all DDS line rates in a single unit: Async rates from 2400 bps to 57.6 kbps, and sync rates from 2400 bps to 64 kbps Clear Channel. Added versatility to operate as a limited distance modem over unloaded twisted-pair cable, with maximum distances up to 28 miles (19 gauge wire). Automatic line equalization ensures optimum performance and reliability in extended range applications. Switch-configurable EIA-232 or V.35 interfaces for built-in flexibility. Convenient 32-character LCD for easy configuration. Fully test loop compatible with DDS/MR56 and MR1. Two-year repair/return warranty from Telenetics.
