The MetroCONNECT MC12000 offers a high density flexible Ethernet Service Delivery solution with fibre or copper distribution from the core network to customer sites. Various I/O modules can be used to deliver Ethernet services over a wide variety of last mile services to matching standalone devices performing managed LAN extension or managed media conversion functions. Support for 10M, 100M and Gigabit Ethernet applications as well as Jumbo frames comes as standard across this product range. Comprehensive end-to-end management is supported using 802.3ah or IP, offering visibility right up to the customer demarcation point.

The MC12000 is a 4U, 19 inch rack based chassis unit supporting up to 2 power supply modules (PSUs) and 12 I/O modules supporting up to 48 services. Spare I/O modules can be resident in the chassis ready for the immediate deployment of additional capacity or to provide “in situ” spares. The “hot swap” capability of I/O modules and power supplies eases the provisioning of new services and the maintenance of existing services. With multiple access links deployed, resilience can be supported using G.7042 LCAS and/or RSTP.

A wide variety of last mile service delivery types can be supported including:

• Ethernet over copper or fibre via FCC9000 I/O modules linked to FCM9003 Ethernet Access Device (layer 2/layer 3) or FCM9005 Ethernet Demarcation Device (layer 2/layer 3) remote site units
• Fractional E1/ T1 services via WCC1400 or WCC1800 I/O modules linked to WCM1100, WCM1101, WCM1400, WCM1800 or WCM1820 remote site units
• Framed E3/DS3 services via the WCC3200 I/O modules linked to WCM3100, WCM3200 or WCM3400 remote site units
• STM-1 services via WCC5200 I/O modules linked to WCM5100 remote site units
• Serial services via WCC-Serial I/O module and WCM-Serial remote site units

For example:

• The FCC9000 I/O module is used with the standalone FCM9003 deployed at the customer site to deliver a 10/100/1000baseT or fibre Ethernet service over a fibre WAN connection, with up to 24 individual Ethernet services being delivered via a single MC12000 chassis, alternatively
• Each WCC1400 I/O module can support 4 standalone WCM1100 or WCM1101 units deployed at different customer sites to deliver 4 separate 10/100/1000BaseT or fibre Ethernet services over fractional E1 or T1 circuits, with up to 48 individual Ethernet services being delivered via a single MC12000 chassis.

The MC12000 only requires a single PSU to support a full compliment of I/O modules, but for increased resiliency redundant PSUs can be used. The PSUs are load sharing when used in the optional 1+1 redundant configuration. For maximum MTBF (mean time between failures) the -48V DC PSU modules may be used.Typical operating power consumption is less than 75 watts.

The MC12000 system management module manages each of the I/O modules and has the ability to extend management to remote demarcation devices and beyond, via IP or OAM messages with separation using VLANs. The I/O modules optionally generate and terminate OAM frames according to IEEE 802.3ah. Each I/O module supports standalone operation with defaults configured using simple bit switches for ease of installation, which can then be overridden by the management software.

Management of the MC12000 is either via the console port, or the management Ethernet port using SNMP, Telnet or a Web browser. SNMP traps are generated based on I/O module alarms which can be individually enabled. TFTP download of software and configuration is also supported. To further future proof the MC12000 system, remote hardware upgrade of CPLD firmware is possible. Management access has password protection whether via the console, Telnet or browser interface. Performance statistics are available for all ports with data collection in 15 minute segments for a 24 hour period. For security, the MC12000 supports SSH and TACACS+ for access control.

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