MultiDSU Family Highlights

Competitively Priced.  The MultiDSU family has been streamlined to provide the most important DSU features, while eliminating costly extras you'll never use. This means Multi-Tech DSUs are competitively priced, easy-to-use, yet highly reliable.

Easy to Setup and Maintain.  The MultiDSU family installs easily, and once installed requires little to no maintenance. You simply plug the line service and DTE equipment into the MultiDSU, configure with dip switches or terminal, and you're up and running. And when necessary, built-in test capabilities let you quickly troubleshoot line problems.

Cost-Effective.  Manage high-speed connectivity costs with the right MultiDSU and line service. In limited use applications, a 56K MultiDSU and switched 56K digital dial-up service are ideal. You pay a low monthly fee and only for the time used. To provide 24-hour on-line service, use a 56K or 64K MultiDSU and Digital Data Service (DDS) for up to 56K or 64K Clear Channel® dedicated service over a 4-wire line. For data intensive applications, like video conferencing and LAN-to-LAN routing, a T1 MultiDSU and T1 line provide dedicated 1.544M service.

T1 MultiDSU

The T1 MultiDSU is a low-cost, full-featured DSU/CSU that provides access to digital networks at T1/FT1 speeds. It provides access to traditional dedicated point-to-point T1 services, Frame Relay, SMDS, and ATM services. The T1 MultiDSU is ideal for LAN-to-LAN bridging, Frame Relay, and video conferencing applications.

Supports synchronous equipment at 56K to 1.536M
Connects to T1/FT1 lines for 56K to 1.536M rates
Provides one V.35 DTE interface
Supports D4 Superframe or Extended Superframe and B8ZS or AMI line coding
Supports Facilities Data Link (FDL)
Provides BPV/CRC, ES, SES, FS, OSS, and alarms
Provides a terminal interface for configuring and monitoring

64K MultiDSU

The 64K DSU combines the flexibility of an RS-232 or V.35 DTE interface with 56K dedicated, 56 switched, or 64K DDS line connectivity.

Supports synchronous equipment at 9.6K to 64K and asynchronous equipment at 9.6K to 57.6K
Connects to a 56K switched, 56K dedicated, or 64K Clear Channel DDS line
Provides one RS-232C/D and one V.35 DTE interface
