RAD's Megaplex-4100 is a carrier-class, high-capacity multiservice access concentrator for transporting legacy and next-generation services over fiber or copper PDH/SDH/SONET, or over packet switched networks (PSN). Its ability to handle a broad range of Ethernet, data and voice services, as well as a large variety of network technologies in a single compact managed node, makes the Megaplex-4100 an ideal core/edge solution for carriers and service providers. It also provides a perfect fit for large enterprises, utilities and transportation companies, who require an efficient way toPDH/SDH/SONETand provision multiple legacy and next-generation services over their high capacity pipes.

Megaplex-4100 is part of the AXCESS+ portfolio of multiservice access and First Mile solutions.

  • Smooth and cost-effective migration from TDM to PSN
  • Reduces CapEx with a single device handling all enterprise communications requirements
  • Improved line efficiency and lower latency for delay-sensitive application
  • Optimizes bandwidth consumption of under-utilized lines by grooming Fractional E1s
  • Reduces OpEx by converging services over shared media

As a modular multiservice access node, the Megaplex-4100 provides an efficient and cost-effective solution for integrating various interfaces, data rates and user services. These include Fast Ethernet and Gigabit Ethernet as well as low speed sub-64 kbps data, serial n x 64 kbps data, high speed data up to STM-4/OC-12, digital voice, analog voice, ISDN, and additional industry specific interfaces. Furthermore, the device functions as a carrier-class TDM and Ethernet aggregator, as well as high capacity DS0 cross connects, as detailed below.

Carrier-class Management

The Megaplex-4100 supports carrier-class service provisioning and end-to-end path management to ensure continuous service availability. Advanced SNMP management capabilities support control and monitoring of all network elements: SDH/SONET access and ring units, as well as remote POP and First Mile broadband access feeders and CPEs.

The device is managed by the RADview-SC/TDM Center application. Alternatively, configuration and monitoring can be performed via either Telnet or an ASCII terminal using RAD command line interface (CLI).

In addition, the Megaplex-4100 supports the latest security protocols, including SNMPv3, RADIUS and SSH.

Smooth migration from TDM to PSN

The Megaplex-4100 supports legacy services over packet switched networks, using the MPW-1 module to convert the data stream from other modules to Ethernet, IP or MPLS packets with TDMoIP, CESoPSN, SAToP, and HDLCoPSN pseudowire technologies. The device's ASIC-based architecture provides a robust pseudowire solution with minimal processing delay.

Ethernet and TDM aggregation

The Megaplex-4100 offers an end-to-end solution as central aggregation platforms for diverse CPE devices, including RAD’s ASMi, Optimux, Megaplex, IPmux, RICi, FCD, DXC, and ETX lines.

The device can terminate TDM and Ethernet traffic carried over E1/T1 links, fiber, or SHDSL, as well as over VCGs in STM-1/OC-3 and STM-4/OC-12 links. This traffic can then be switched either to a different PDH/TDM trunk or to the Fast Ethernet or Gigabit Ethernet ports.

Various users can benefit from this solution:

Carrier-class service reliability

The modular, distributed architecture of the Megaplex-4100 enables redundancy at the hardware, link and service path levels, to provide a resilient system with no single point of failure and under-50 ms switchover time.

In addition to supporting standard SDH/SONET rings, the device can be used to create E1, T1, TDM over SHDSL, TDM over fiber, or a mix of ring topologies.

The Megaplex-4100 features a wide range of diagnostics, performance monitoring and alarm mechanisms.

Next-generation ADM terminal

The Megaplex-4100 supports STM-1/OC-3 and STM-4/OC-12 add/drop multiplexing for grooming LAN and TDM traffic over SDH/SONET networks. It eliminates the need for separate ADM and multiplexer units for private networks where voice, Ethernet and data services are required.

By implementing VCAT protocols to carry Ethernet traffic efficiently and minimize wasted bandwidth, the device brings Ethernet economics and packet switching efficiency to existing SDH/ SONET infrastructure. It enables utilities and other private fiber network owners to reduce both OpEx and CapEx, while service providers can leverage existing equipment to support clear channel data streams and the latest high bandwidth services.

Ethernet traffic can be mapped into n x VC-12/VC-3/VC-4 or n x VT 1.5/STS‑1/STS-3C virtual containers.

Parallel TDM and Ethernet processing

The Megaplex-4100 features dual-star connection architecture with hybrid TDM-Ethernet modules, which allow native TDM and Ethernet traffic handling with minimal encapsulation delays and zero bandwidth overhead.

Ethernet traffic is handled by a multiport Gigabit Ethernet aggregation engine, designed for Carrier Ethernet capabilities, such as flow-based or port-based traffic management, performance monitoring and Ethernet OAM. Ethernet traffic can be terminated by any of the following:

TDM traffic can be cross connected at a DS0 level, DS1 (framed/unframed) level, or SDH/SONET (high/low order) level, with per-port cross connect operation mode selection.

DS0 cross connect

The device features an internal DS0 cross connect matrix of up to 7,872 DS0 channels. Traffic from any channel can be cross connected directly to any other channel.

These capabilities enable the device to function as a service differentiation point at the central office, handing off TDM voice and data services to the transport network. It can also be deployed at remote locations or the customer premises to effectively fan out multiple voice and data services.

CL.2 modules

The CL.2 modules function as common logic, cross connect and broadband link modules, and are available in a number of port configurations. For direct connection to the SDH/SONET network, CL.2 features two standard network ports with software configurable STM-1/OC-3 or STM-4/OC-12. The dual ports on the CL.2 module can be used for either parallel operation or for redundancy.

For direct connection to packet-based networks, CL.2 has two UTP or SFP-based GbE ports. The UTP interface features auto-negotiation and fast detection capabilities.
