T1 and DDS CSU/DSUs
RayTel Motorola 3512 DDS CSU/DSU, Sync / Async

The Motorola 3512 is a legacy CSU/DSU for DDS and DDS2 is based on the Motorola 68000 microprocessor and supports a broad range of digital applications, including Time Division Multiplexing, and Lease Line Services.

• 2 or 4 Ports - 2 and 4 port point-to-point/multipoint Time Division Multiplexing (TDM) options to reduce line and equipment costs.
• All DDS Services - Supports all major digital leased line services; DDS/DDS II Secondary Channel to 56Kbps and 64Kbps Clear Channel.
• Network Management - Non-disruptive network management via Motorola 9000 series Open Management System (OMS) ensures rapid fault isolation (3512 NMS) and IBM NetView� network management (3512 NMS).
• Remote Configuration - Unattended remote configuration, testing and monitoring through remote front panel.
• Integrated Analog Modem - Integral V.32bis or 4-wire Switched 56 restoral options for continuous transmission.
• Integrated A/B Switch - Integral A/B switch for restoral via 2-wire DataPath� SW56/64, ISDN BRI or V.34 class modems (3512 with 2/4 port options).
• Topology Support - Point-to-Point and Multipoint Rate Adaption.
• Rack Mountable - Standalone or rack-mountable configurations available.

The Raymar-Telenetics 3512 is available in either front panel controlled or network managed versions. With the 3512 NMS version, command and control is provided using the Motorola 9000 OMS series over the main channel, carrier provided secondary channel, or derived secondary channel.

With standard Dual VIEW™, the 3512 NMS provides a direct interface to IBM’s NetVIew™, as well as the Motorola 9000 OMS series. The Netware Loadable Module (NLM), WANVisible™, in NetWare servers, provides monitoring of the 3512 NMS and digital circuits.

FLEXIBILITY

Packaging of the 3512 also offers flexibility with 1, 2, or 4-port standalone or nest card versions. For space savings at the central site, the 3512 is rack-mountable.

EFFICIENCY

A variety of operating modes allow the 3512 DSU/CSU to respond to user network requirements for optimum operating efficiency. As digital networks evolve, the 3512’s support for multiple digital services and speeds will allow it to adapt to changing needs without requiring costly upgrades.
