MC12000 supporting Multiple Carrier Ethernet Demarcation / LAN Extension Devices

MetroConnect Solution for Carrier Ethernet Service Demarcation

This application shows an MC12000 MetroCONNECT chassis with WCC1400 modules, supporting multiple WCM1400 Ethernet Extenders over bonded E1 or T1 services. The MetroCONNECT and WCM1400 together offer Ethernet Extension and Ethernet demarcation, with remote management via 802.3ah OAM. Various service delivery options are available including fibre, copper, and fibre plus copper over up to 4 Fractional E1 or T1 circuits. Comprehensive remote network management access is available via the MetroCONNECT including end to end remote management using 802.3ah OAM. 10M, 100M and Gigabit Ethernet applications can all be supported, as can Mini Jumbo frames.

This application shows an WCM1400 unit being used as the Ethernet Extension demarcation device to deliver a Carrier Ethernet service from an MPLS core network. A wide choice of Ethernet connectivity is available for the user via the 10/100/1000baseT and SFP fibre ports. OAM support means that the WCM1400 can be remotely managed by the central network management system using standards based OAM packets. GFP is supported allowing single ended use with aggregation platforms in the core network.

This application shows how VLANs can also be used to select which site to forward user data to, e.g. when using a WCM1400 unit supporting four E1 ports at a central site supporting up to four sites with WCM1100 units each supporting a single E1 port.

The WCM1400 is a member of the MetroCONNECT family, offering Managed LAN extension over either Clear-Channel or Fractional E1 or T1 Wide Area Networks.The WCM1400 supports four locally switched RJ45 LAN interfaces, three of which are for 10/100Mbps connections and the fourth supporting 1Gbps. A further LAN interface is provided via an SFP port, offering the flexibility of a wide variety of fibre interface options. Over-sized Ethernet frames are supported.

Ethernet VLANs are supported, either by pass-through of existing Tags or by the Push and Pop of Tags on ingress and egress at Ethernet ports. Pre-embedded prioritisation schemes can be honoured, or alternatively prioritisation can be over-written under Management control.Bandwidth limitation per port and per prioritisation can be implemented, providing a mechanism for differentiated QoS for different services. 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 (IEEE 802.3ah), 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 WCM1400 supports Metrodata’s ‘zero-touch’ installation process, eliminating the need for skilled resources for remote-site installations.

The WCM1400 supports integrated ‘Bit Error Rate Testing’ (BERT), an invaluable aid during both installation and subsequent troubleshooting. This facility enables integrity testing of the WAN link, prior to application of Ethernet traffic, eliminating doubt as to the location of connectivity problems.

Ethernet traffic is encapsulated by the WCM1400, for transmission over an E1 or T1 link, using a number of optional schema including support for the ITU-T G.8040 standard ‘Generic Framing Procedure’ (GFP). The product can be used for Point-to-Point links, using two WCM1400 products joined via multiply ‘bonded’ terrestrial or wireless (e.g. microwave) WAN services, to provide seamless Ethernet bandwidth of up to ~8Mbps between two locations. Alternatively, the product can be used in conjunction with other members of the MetroCONNECT product family, including the WCM1100,WCM1800,WCM1820 and MC12000 Ethernet Service Delivery Chassis. As a small ‘Central Site’ aggregator, the WCM1400 may serve combinations of single and/or bonded WAN links to between one and four separate locations.

The WCM1400 is available in a choice of 100-250 VAC or -48 VDC integrated power supplies.

The WCM1400 can easily be rack mounted in either a 1U two unit rack mount kit, a 6U eighteen unit rack mount kit.

The WCM1400 is part of a wide range of LAN extension products from Metrodata.
