Motorola/Codex 3512
Data Service Unit (DSU),
with integral Channel Service Unit (CSU)

Overview

The Motorola 3512 Data Service Unit (DSU), with integral Channel Service Unit (CSU), is an intelligent, multi-rate digital product, with multi-channel and restoral options ideally suited for today's digital environment. The 3512 is available in both managed (3512 NMS) and non-managed (3512) versions. Based on the Motorola 68000 microprocessor, the 3512 supports a broad range of digital applications, including:

2 and 4 port point-to-point / multipoint Time Division Multiplexing (TDM) options to reduce line and equipment costs

Supports all major digital leased line services; DDS / DDS 11 Secondary Channel to 56Kbps and 64Kbps Clear Channel

Integral V.32bis or 4-wire Switched 56 restoral options for continuous transmission

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)

Point-to-point and multipoint rate adaptation

Standalone or rack-mountable configurations

Non-disruptive network management via Motorola 9000 series Open Management System (OMS) ensures rapid fault isolation (3512 NMS)

IBM NetView network management (3512 NMS)

Unattended remote configuration, testing and monitoring through remote front panel

The 3512 is available in either front panel controlled or network managed versions. With the 3512 NNIS 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 DualView, 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 NNIS and digital circuits.

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.

A variety of operating modes allow the 3512 DSUCSU 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.
