The Megaplex main links and user ports incorporate copper, CSU/DSU, LTU, and fibre interfaces and are compatible with RAD's standalone ASMi-31, ASMi-52 and FCD modems. The Megaplex 2200 modular integrated access multiplexer is especially suitable for use as an economical, compact remote distribution node. It is ideal for small to mid-size business entities, providing mixed services for both business and residential customers. It can be deployed at the carrier's point-of-presence in the exchange, as well as at a remote distribution node, such as in an office building's basement. Megaplex 2200 modular integrated access multiplexer is standards-compliant, ensuring compatibility in multivendor environments worldwide. The E1 and T1 TDM framing and signaling, PCM/ADPCM voice coding, ISDN and data interfaces all conform to international standards. The 1/2/4 E1/T1 main links support 1+1 and 1:1 protection switching for any E1/T1 fractional E1/T1 port with non-blocking cross connect capability. This provides drop-and-insert capability between any two links on one or between two modules. Megaplex devices store up to 10 different configuration databases and can switch between them. This feature enables alternate routing in the event of network or service failure, or at a predetermined time. The optional redundancy on common logic, main link and power supply ensures a high level of system reliability on Megaplex hubs. The Megaplex 2200 modular integrated access multiplexer units allow hot-swapping of all modules. Extensive network management is provided on multivendor management platforms using Megaplex with standard SNMP protocol. Megaplex provides the control and monitoring required in large networks using the RADview element manager platform. The Megaplex 2200 modular integrated access multiplexer is also supported by the RADview TDM Service Center and the RADview TDMoIP Service Center, allowing the service allocation to be provided at the click of a mouse button. The Megaplex 2200 modular integrated access multiplexer can be mounted in 19" or 21" racks for carrier and service provider environments. V5.1 and V5.2 interface supportV5, the ETSI standard interface, operates between the access network and the Class 5 switch for basic telephony, ISDN and semi-permanent leased lines. The V5 standard effectively opens the access network to competition and allows operators to deploy optimal access technology. The Megaplex 2200 modular integrated access multiplexer incorporates a V5 main link interface to facilitate connection of residential and SOHO users of PSTN and ISDN services to local exchanges with a V5 interface. The V5.2 (which is an extension of the V5.1 standard) allows oversubscription of services based on dynamic on-demand assignment of timeslots for optimal utilization of available bandwidth on the physical link. The Megaplex implements V5.2 with up to four physical E1 lines per V5.2 interface. The Megaplex V5.2 platform exists in two separate different versions: • V5.2 endpoint gateway, allowing voice, ISDN and fractional/full E1 services with payload of up to 120 channels • V.5.2 exchange gateway, allowing multiple full/fractional E1 lines to be connected to one V5.2 interface. In this mode, the Megaplex can handle a user payload of up to 44 full E1s. R2 supportThe Megaplex 2200 modular integrated access multiplexer also includes R2 support with transparent MFC/decadic implemented within the main link. This allows the customer to connect a legacy R2-PBX to a digital (E1 CAS) PBX, thus extending the life span of existing equipment. TDM over IP supportMegaplex 2200 modular integrated access multiplexer incorporates RAD's TDMoIP technology in the ML-IP main link module. This enables all existing TDM services to be transported over packet-switched networks. With the ML-IP module, the Megaplex can be connected in a daisy-chain topology where multiple Megaplex units can be cascaded together. TDMoIP support also allows the Megaplex 2200 modular integrated access multiplexer to operate opposite the IPmux family of TDMoIP gateways. Along with TDMoIP, Megaplex supports Resilient Fast Ethernet Ring (RFER) with under 50 msec ring restoration capabilities. Up to 40 E1 or 50 T1 TDM circuits can be connected per Fast Ethernet ring or daisy-chain. The addition of TDMoIP functionality further expands the broad scope of solutions supported by the Megaplex family. For more information about the TDMoIP concept, please refer to the TDM over IP chapter. ManagementNetwork management provides centralized control of all network nodes, including interface configuration, connection setup, alarms, and management. All parameters are user-programmable for up to 10 independent configurations (10 databases per unit). All configurations are saved in non-volatile memory. Alarm status and system configurations are available at all times. Multiple Megaplex hubs can be controlled from a single PC or UNIX workstation. The Megaplex 2200 modular integrated access multiplexer can be managed also via the RADview Service Center (for path management) or by third-party path management applications via a CORBA interface. Programming and setup of a remote Megaplex device is accomplished: • out-of-band, through the Ethernet port • out-of-band, through the supervisory port of the remote unit, over a modem link or FRAD • in-band, using a dedicated timeslot, dedicated FR, PPP or TS0. DiagnosticsMegaplex 2200 modular integrated access multiplexer incorporates test features for rapid fault detection and easy maintenance. Once in operation, all system and I/O modules undergo self-testing, and problems are reported to the management system. Local and remote loops may be performed on each channel and on the main links. Any timeslot can be selected for BERT/tone injection. In addition, a loop can be initiated per any timeslot. Signaling monitoring - the ABCD status of any voice channel can be captured with a single click. AlarmsAlarm information is stored in the common logic module and is automatically read by the management system from any node. Up to 256 alarms can be stored in a queue and a maximum of 1,024 alarms can be stored in a file on the PC, to be read by the management system. System modulesThe common logic module stores configuration and event information, and uses a SLIP/PPP or Ethernet connection to communicate with the management station via an SNMP agent. Flash EPROM for remote software download, Telnet and an ASCII craft terminal are also supported. Main link modulesThe 1/2/4 E1/T1 and ML-IP main link modules incorporate the DS0 matrix between the I/O channels and each of the E1/T1 trunks. The modules support 8 Mbps non-blocking cross connect for any DS0 coming from either the channels or from the trunks. Multiple fractional E1/T1 ports are supported. The main link supports 1+1 protective switching within 50 msec for any E1/T1 port. Four timing options are available:• Link receive clock• Internal crystal oscillator channel• Clock from any high speed module (HS-12N/6N, HS-S, HS-U, HS-703, HS-Q/M, HS-Q/N, HS-2)• Station clock Any clock source can be set as the fallback in the event of primary clock source failure. Ring support (E1/T1 and RFER)The Megaplex 2200 modular integrated access multiplexer supports various ring topologies ensuring "no single point of failure." E1/T1 ring protection provides self healing in less than five seconds. Resilient Fast Ethernet Ring (RFER) provides a 100 Mbps (up to 40 E1/50 T1) Ethernet ring with self-healing in less than 50 msec. The 6U high Megaplex-2200 modular integrated access multiplexer has 12 slots for both I/O and main link modules. This allows for a mix of a wide variety of data, voice, fax, video and LAN services.
