The WCM-Serial is a member of the MetroCONNECT family, offering Managed local Ethernet Switching at up to 1Gbps and LAN extension over serial services. Support is offered for fractional (including Nx 64Kbps) X.21,V.35 and EIA-530 services up to 20Mbps.The WCM-Serial supports auto negotiation and auto MDI/MDI-X cross-over switching on two RJ45 LAN interfaces.A further LAN interface is provided via an SFP port, offering either an additional RJ45 connection or a variety of multi-mode and single-mode fibre interface options.

Link Loss Forwarding is supported, whereby faults on the uplink port 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 is supported, with internal packet buffering used to smooth out bursty traffic without packet loss.

Management is offered via each of; Serial Terminal connection, Telnet, SNMP or Web Browser application. Management security is offered via SSH and TACACS+ authentication. Support is also offered for ‘Carrier Ethernet’ Link OAM Management (IEEE802.3ah), enabling status information to be shared with connected equipment if required.

In line with all other members of the MetroCONNECT Ethernet Service Delivery family, the WCM-Serial supports Metrodata’s zero-touch’ installation process, minimising both on-site installation time and the Engineering skills required. Our unique ‘IP proxy over OAM’ functionality reduces on-site installation to a ‘plug and play’ exercise, simply checking that Ethernet link-up LEDs indicate correct physical connectivity. Comprehensive Telnet and/or SNMP remote management is available to the device via an IP proxy process across Layer-2 OAM traffic from an MC12000 Service Delivery chassis or another MetroCONNECT family device at the network centre, with no need for layer-3 (IP) parameters to be assigned locally. If required, individual configuration can be subsequently downloaded via TFTP.

The WCM-Serial supports VLAN in two ways. In normal mode,VLAN tagged frames are passed unmodified; however when VLAN support is enabled, the WCM-Serial supports VLAN tag-based switching whereby access may be controlled using VLAN IDs.The unit is password protected for Telnet access for security, and for SNMP is configured with a primary and multiple back-up NMS stations. SNMP access will only be accepted from an authorised NMS.

Compatibility: GFP mode for use with LAN Extension Aggregation equipment

The WCM-Serial is available in a choice of 100-250 VAC or -48 VDC integrated power supplies.

The WCM-Serial can easily be rack mounted in either a 1U two unit rack mount kit , a 6U eighteen unit rack mount kit.
