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. --------------------------------------------------------------------------------   -------------------------------------------------------------------------------- Specifications Service Types Digital transmission services conforming to AT&T Technical Reference 623 10 and related Bellcore publications Operating Mode Full-duplex, point-to-point and multipoint (56Kbps DS-11 SC and 64Kbps Clear Channel are supported point-to-point only) Digital Aggregate Interface Point-to-point and multipoint DDS-1 type facilities: 2.4*, 4.8*, 9.6, 19.2 and 56kbps DDS-11 SC type facilities: 3.2, 6.4, 12.8, 25.6 and 72 Kbps providing primary channel rates of 2.4, 4.8, 9.6, 19.2 and 56Kbps respectively, plus secondary channel 64Kbps Clear Channel facilities: 72Kbps providing 64Kbps primary channel rate Private wire facilities: 2.4, 4.8, 9.6, 19.2, 56 and 64Kbps plus DDS-11 SC aggregate rates; point-to-point only Data Format Synchronous: serial, binary Asynchronous: serial, binary 6 - 9 bit including parity bit Data Encoding Bipolar, return to zero, alternate mark inversion Port Timing Network, internal, external or station DSU Timing Network, internal or external (external for DDS-I only, the line rate must be an integer multiple of the port rate) Digital Port Interface User selectable EIA 232-D or V.35 on ports I through 4; front panel selection 25 Pin DB-25 connector (port 1); DB25N.35 physical conversion via available 3512 attached adapter or adapter cable EIA 232-D alternate DB-26 subminiature connectors (ports 2 through 4) DTE Port Rates Synchronous: 1.2, 2.4, 4.8, 7.2, 9.6, 12.0, 14.4, 16.8, 19.2, 21.6, 24.0, 28.8, 32.0, 38.4, 48.0, 56.0 and 64Kbps Asynchronous: 1.2, 2.4, 4.8, 7.2, 9.6, 14.4, and 19.2Kbps Maximum DTE Port Rates Derived Secondary Channel Mode: Port/line rates: 2290/2400*, 4688/ 4800*, 9487/9600, 19019/19200, 55200/56000 and 62400/64000bps with standard DTE port rates selectable at user option Network Management: 9000 OMS Series IBM NetView Via DualView at line rates to 56Kbps -NetView Version 1.3 or later. -ACF/NCP Version 4.2 or later Lines configured for either SDLC or BSC Novell NetWare With WANVisible NLM NetWare versions 3. 11 and 4.0 Network Control Channel: Data format: Asynchronous, serial, binary, compatible with Motorola network management systems Data rate: Selectable 75, 150 and 9600 bps Management Protocols Supported Motorola Proprietary Protocol Link Problem Determination Aid (LPDA) Revision 2 (user data ports only) Power Requirements 3512 Standalone: 110 VAC nominal 47 to 63 Hz 3512 Nest Card: 110 or 230 VAC 47 to 63 Hz Environment Operating temperature: 32' to 122' F (0' to 50'C) Non-operating temperature: -40 to 158F (-40 to 70C) Operating relative humidity: 10% to 95% (non-condensing) Physical Dimensions 3512 DSU / DSU Standalone: Height: 23in (5.8 cm) Width: 6.6 in (16.8 cm) Depth: 9.6 in (24.4 cm) Weight: 2.5 lbs (I.
