Ethernet Extender over 2x bonded E3 or DS3

The Metrodata WCC3200 provides a high performance Ethernet over 2-port Framed E3/DS3 LAN extension function for the MC12000 chassis.

Gigabit Ethernet over/Fibre over E3/DS3 Services

  • 10/100/1000BaseT Copper Port
  • SFP socket supporting:
    • 1000Base-X
    • 100Base-FX
  • Optional:
    • Fibre over 2-port Framed E3/DS3
    • Copper over 2-port Framed E3/DS3
    • Fibre and Copper over 2-port Framed E3/DS3
  • Link Loss Forwarding
  • Mini Jumbo Frame Support (2048byte)
  • 802.3ah OAM Support
  • 802.1q VLAN support (pass-through and tag switching)
  • 802.1p priority queuing (4 queues)
  • RSTP support
  • TACACS+ for secure authentication
  • “Hot Swap” IO Module
  • Store and Forward Media Conversion
  • Interoperates with WCM3200 customer site unit

The WCC3200 is an I/O module for use in the MC12000 system.

The WCC3200 occupies a single slot in the MetroCONNECT MC12000 chassis and is fully “Hot Swap” compliant to ease maintenance and the provisioning of new services.

Each Module supports Ethernet over 2-port Fractional E3/DS3 LAN Extension and Ethernet Demarcation functionality and supports Copper, Fibre or Copper and Fibre over 2-port Fractional E3/DS3 operating modes. Link Loss transparency / forwarding is supported.

Optionally, the WCC3200 may be enabled to support OAM link management according to IEEE802.3ah. When OAM is disabled, the WCC3200 operates in a fully transparent LAN Extension mode.

The future WCC3200 development roadmap includes support for IEEE802.1ag and Y.1731 OAM standards.

The SFP port auto senses the SFP type inserted, based on the Module Definition and configures the port for 100BaseFX or 1000Base-X operation.

The WCC3200 supports auto-negotiation, and auto MDI/MDIX cross-over switching on the copper interface.

The WCC3200 supports the transmission of Mini Jumbo frames.

MetroCONNECT Solution for Ethernet Service Demarcation
WCC3200 and WCM3200 offering Ethernet over 2-port Framed E3/DS3 LAN Extension at the edge of the core network

This application shows how WCC3200 modules within a MC12000 chassis can be used to perform an Ethernet over 2-port Framed E3/DS3 LAN Extension function. Electrical connection into the core network potentially improves port density and therefore utilisation levels, but fibre connectivity is also available. The WCM3200 is a standalone version of the WCC3200 module offering Ethernet service demarcation at the customer site.

Many other transceivers are available on request including long haul, 1550nm, CWDM, DWDM and bi-directional.

Whilst the MetroCONNECT product range uses industry standard user exchangeable SFP and SFP+ transceivers, it is recommended that these are purchased from Metrodata to guarantee their specification and compatibility with each other.

If you require another transceiver please contact our sales team with your requirements.
