System Modules

---

 

• The Common Logic module stores configuration and event information, and communicates (via a SLIP/PPP connection) with the management station by means of an SNMP agent. Flash EPROM for software download, TELNET and ASCII terminal are also supported.

  Main Link Modules

  ---

   

• E1 (with or without LTU), T1 (with or without CSU/DSU) or hybrid main link modules support a wide range of access media (copper, coaxial and fiber optic).

• Hybrid main link allows flexible configuration by enabling timeslots to be defined as either Frame Relay or TDM.

• The main link modules can be configured for single non-redundant operation, or for dual link operation supporting either drop & insert, redundancy or load sharing. Up to 62 timeslots can be supported over two links.

• Four timing options are available:
  - Link receive clock
  - Internal crystal oscillator channel
  - Clock from any high-speed HS-2 or HS-4 module
  - Station clock (MP-2100B/F only) Any clock source can be set as fallback in the event of primary clock source failure.

I/O Modules

---

 

• Up to 11 I/O modules can be placed in a Megaplex-2100 chassis (four in the Megaplex-2104).

• Where more than 11 I/O modules are required, two Megaplex-2100 units can be cascaded.

  Types of I/O Modules

• High speed data modules

• Low speed data modules

• Voice/Fax modules

• LAN modules

TDM Modules

---

 

High Speed Data Modules

• High-speed synchronous data interface modules, operating at multiples of 56 kbps and 64 kbps, up to 2.048 Mbps. Various modules support ISDN BRI interfaces for ISDN extension over non-ISDN facilities and IDSL technology for "last mile" applications.

  Low Speed Data Modules

• Sub-rate multiplexer modules for low speed (1.2 to 19.2 kbps) synchronous and asynchronous data channels. Various modules support standard X.50, DS0-A, DS0-B, built-in tail-end modems, V.110 rate adaptation. Efficient sub-rate multiplexing technique (compatible with Kilomux-2000) is also supported.

  Voice/Fax Modules

• Multiple voice channel interface modules, that can directly connect to analog lines for direct telephone connection, PABX extension connection or 2/4-wire, E&M connection. Alternatively digital interfaces for E1 and T1 are also supported. Voice/fax modules support PCM, ADPCM and high quality MPMLQ (ITU - G.723) compression algorithms.

  LAN Modules

• Ethernet router and Token Ring internetworking modules, compatible with the LAN RANger remote access family or other vendors' routers/bridges.

Frame Relay Modules

---

 

Low Speed Data Modules

• Supporting up to six sync/async data channels. Selectable data rates from 0.3 to 64 kbps. Support protocols HDLC/SDLC, async, Transparent, Frame Relay, Cell Relay, Frame Relay +.

  High Speed Data Modules

• Supporting up to three sync data channels. Selectable data rates from 32 to 384 kbps. Support protocols HDLC/SDLC, Frame Relay, Cell Relay, Frame Relay +.

  Voice/Fax Modules

• Low bit rate compressed voice/fax digitizer supporting up to four analog voice/fax channels. Uses MPMLQ-based voice compression to ensure high voice quality.

Management

---

 

• The Megaplex-2100 can be managed by a UNIX-based or PC-based SNMP management system. The software is user friendly, GUI based and runs under PC/Windows (RADview-PC/WAN) or HP-Openview UNIX (RADview-HPOV/WAN) systems. In addition, configuration and monitoring is provided via TELNET or a dumb terminal.

• Network management provides centralized control of all network nodes, including interfaces configuration, connection setup, alarm and management.

• All parameters are user programmable for up to 10 independent configurations (databases). All configurations are saved in non-volatile memory.

• Alarm status and system configurations are available at all times. Multiple Megaplex-2100 chassis can be controlled from a single PC or UNIX workstation.

• Programming and set-up of a remote Megaplex-2100 is accomplished either:
  - Via timeslot 0
  - Through the supervisory port of the remote unit, over a modem link or over a FRAD
  - Over a full in-band dedicated timeslot, supporting PPP and RIP2 standard protocols.

  Diagnostics

• Megaplex-2100 incorporates test features for rapid fault detection and easy maintenance. Upon power-up, all system and I/O modules undergo self testing. All problems are reported to the management system. Local and remote loops may be performed on each channel and on the main links.

• An internal test pattern generator available on some I/O modules allows on-line testing of individual channels without using external test equipment.

  Alarms

• Alarm information is stored in the common logic module. Alarms are automatically read by the management system from any node. Up to 256 alarms can be stored in a queue and up to 1024 alarms can be stored in a file on the PC, to be read by the management system.

Megaplex-2100 is comprised of a Basic Unit (chassis, main link and common logic modules, power supply and cables) and I/O modules. When ordering, specify the basic unit required, plus all I/O modules (see individual main link and I/O module data sheets).

Note: for non-standard requirements, the basic unit can be ordered without a main link module by simply omitting the link interface field (e.g. MP-2100/230). The main link module should then be ordered separately.
