FEATURES

• Megaplex-2200 is a flexible integrated modular multiplexer, supporting up to 120 n x 64 kbps channels. PSTN, ISDN, and data services are supported, either directly, or via built-in IDSL modems compatible with ASMi-31 or other remote nodes with "U" interface. Megaplex-2200 enables integration of multiple dedicated, voice, ISDN, video and LAN channels onto four E1/T1 links. Megaplex-2200 splits the voice and data channels and redirects the traffic to separate trunks, maximizing efficiency by allowing each trunk to be connected directly to the appropriate service.

• Megaplex-2200 is especially suitable for use as an economical, compact remote multiplexer. It is ideal for serving small communities, providing mixed services for both business and residential customers. Megaplex-2200 can be deployed both at the exchange at the point-of-presence, or at the remote distribution node location (such as in a building's basement telecommunication cabinet).

• Megaplex-2200 can be mounted in 19" racks for carrier and service provider environments. Two chassis variants are available:
  - Megaplex-2200B (6U high) with connectors on back (ANSI standard) for the North American market
  - Megaplex-2200F (10U high) with connectors on chassis front (ETSI standard) for the European market.
  Both Megaplex-2200B and Megaplex-2200F chassis varients have slots to support up to 11 I/O modules, in addition to the first main link module. Both allow for hot-swapping modules without disconnecting cables.

• The cross connect matrix used with the four E1/T1 main links and common logic enables management and control of traffic in case of failure. This, together with optional common logic, main link and power supply redundancy, helps to ensure a high level of system reliability on the Megaplex-2200 hubs. Additionally, the four E1/T1 main links support 1+1 protective switching within 50 msec. The main links also support integrated CSU/DSU and LTU.

• Megaplex-2200 is standards-based, ensuring compatibility in multi-vendor environments worldwide. The E1 and T1 G.704 framing and signaling, PCM voice coding, ISDN and data interfaces, all conform to international standards.

• Megaplex-2200 stores up to 10 different configuration databases and can switch between them in case of any network event. This feature enables alternate routing in case of failure.

• Extensive network management is provided on multi-vendor management platforms via the use of standard SNMP protocol. The Megaplex-2200 provides the control and monitoring required in large networks by means of standard UNIX management platforms such as HPOV. For smaller networks, a PC-based SNMP platform is available.

System Modules

• The Common Logic module stores up to 10 databases for independent configurations and events information. It 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

• The four E1/T1 main links module stores the matrix information between the I/O channels and each of the four E1 or T1 links. The module supports non-blocking cross connect for any n x 64 kbps, coming from either the channels or from the links.

• The main links support 1+1 protective switching within 50 msec.

• Four timing options are available:
  - Receive clock from each link
  - Internal crystal oscillator channel
  - Clock from any high-speed module (HS-12, HS-6, HS-S, HS-U, HS-703)
  - Station clock.
  Any clock source can be set as fallback in the event of primary clock source failure.

I/O Modules
Data Modules

• HS-12 and HS-6 with twelve or six synchronous data channels, operating at multiples of 56 and 64 kbps.

• HS-703 with four G.703 64 kbps codirectional channels.

• HS-R with four low speed data channels operating at programmable data rates of 0.6 to 64 kbps for synchronous interfaces, and 0.6 to 38.4 kbps for asynchronous interfaces.

• HS-U/1 with built-in IDSL modem operating at rates from 0.6 to 128 kbps, for ranges up to 5.5 km (3.4 miles) over 2-wire copper lines.

ISDN Modules

• HS-U/I, HS-S supporting ISDN BRI interfaces for ISDN extension over non-ISDN facilities with either "U" or "S" interfaces.

Voice Modules

• VC-12 with twelve PCM voice channel interfaces. Each interface can connect directly to analog lines for direct telephone, PABX extension or 2/4-wire E&M connections.

Management

• 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-2200 hubs can be controlled from a single PC or UNIX workstation.

• Programming and setup of a remote Megaplex-2200 is accomplished either:
  - Via timeslot 0, or FDL bits
  - 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, FR encapsulation, and RIP2 standard protocols.

Diagnostics

• Megaplex-2200 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. Up to 1024 alarms can be stored in a file on the PC, to be read by the management system.
