The WCC5200 is a single slot I/O module for use in the fully managed MetroCONNECT MC12000 system and is fully “Hot Swap” compliant to ease maintenance and the provisioning of new services. The WCC5200 can be used for Ethernet Service Provision, offering LAN extension over up to two SDH STM-1. services.

The WCC5200 has dual STM-1 WAN ports, each of which has two SFP ports and so 1+1 resilience

can be used if required. Each WAN port may be configured to use either VC4 tributaries.

The WCC5200 can operate in aggregation mode, where the LAN frames are switched according to the MAC

destination address for up to 2 remote destinations, or alternatively VLAN or S-VLAN tag switching can be used. The WCC5200 supports single tag push/pop functions.

The WCC5200 offers a fixed copper 10/100/1000BaseT LAN interface, offering auto-negotiation and auto MDI/MDIX cross-over switching. A second SFP-based LAN interface is provided, which supported standard SFP modules offering 1000Base-X, 100BaseFX and 10/100/1000BaseT. This port auto-senses the SFP type inserted, and configures for 1000Base-X or 100BaseFX operation.

Link Loss Forwarding can be supported, whereby faults on both of the uplink ports will automatically force a link down on the user ports to indicate to the attached devices that there is a link problem. The transmission.

of Jumbo frames of up to 10K bytes is supported, with large internal packet buffering used to smooth out bursty traffic without packet loss.

Remote management can be performed using Ethernet OAM, SNMP or Telnet, in conjunction with the Management Module of the MC12000 system.

The WCC5200 supports VLAN in two ways. In normal mode, VLAN tagged frames are passed unmodified; however when VLAN support is enabled, the WCC5200 supports VLAN tag-based switching whereby access may be controlled using VLAN IDs.
