BLC 6000 Blades
BLC 6640-01 Subscriber Trunk Gateway TR-08/GR-303 Interface and Gigabit Ethernet Transport
The 6640-01 Subscriber Trunk Gateway Blade and BLC 6640-01 Assembly provide TR-08 and GR-303 Class 5 switch interfaces for the BLC 6000 Broadband Loop Carrier system.
- COT for Class 5 Switch
- COT for VoIP C2P Transition
- Gigabit Ethernet Transport and Services
- DS1 Transport and Services
- Transparent LAN Service
The 6640-01 Blade converts VoIP traffic to traditional DS1 circuits with TR-08 or GR-303 signaling for connection to a Class 5 switch. Each blade has 8 DS1 ports. When Next Gen softswitches are introduced into the network, the 6640 will directly connect to the packet platform through Ethernet ports, easing the circuit-to-packet transition.
While configured as a GR-303 interfaced multiple 6640-01 blades can operate as a single Interface Group. Multiple interface groups can be assigned to a 6640-01 Blade or group of blades to provide a virtual 1:N redundancy to minimize the impact of a single blade failure on service delivery. The 6640-01 can also cross-connect and transport DS0s over the BLC 6000 IP network. The 6640-01 also supports Transparent Circuit Emulation service by transporting the whole DS1 circuit through the network, either synchronized or with independent clocking.
The 6640-01 also provides Gigabit Ethernet transport for the BLC 6000 system. The 6640-01 is a high performance, wire speed Ethernet switch with 10 Gigabit Ethernet ports that provide 4 optical and 6 copper connections.
The 6640-01 Blade can be deployed standalone as the BLC 6640-01 Assembly, or it can be used in high density deployments with other BLC 6000 Blades in the BLC 6012 high capacity chassis. The single blade BLC 6640-01 Assembly can be stacked with additional units to add capacity and hardware redundancy, and can be stacked with other BLC 6000 units for full system capabilities.
Ethernet Transport Flexibility
The 6640-01 Blade and BLC 6640-01 Assembly are intended primarily as central office terminals for a BLC 6000 network. The Ethernet transport capabilities of the blade allow it to be the COT component for a wide range of network applications. The flexibility of Ethernet switching allows any port to be used for any service or transport. The 4 fiber Gigabit Ethernet ports, connected to other blades in the network, can be used to create a 1 GigE feeder transport network with a virtually unlimited number of nodes and topologies. This flexibility makes the 6640-01 ideal for high capacity feeder transport for all services in the loop network.
The GigE ports can also be used for customer connections in offering very high speed data services. Transparent LAN services can be provided to corporations, universities and other large customers where VLAN tagging are transported across the BLC network for private Ethernet networking.
The Intelligent Blade Interconnect Architecture of the BLC 6000 features distributed processing intelligence and a unique blade interconnection system that allows unprecedented flexibility for cost effective configurations in low, medium and high density applications. The copper Gigabit Ethernet ports are implemented in pairs and are typically used for protected interconnection with other blades; either in a stack or through the backplane of the high density chassis. The copper GigE ports can also be used to connect other collocated, high speed Ethernet devices to the network such as video headends and Internet routers.
The DS1 ports are used primarily for the TR-08 or GR-303 Class 5 switch connections. However, as part of the overall flexibility of the system, and depending on node configuration, the DS1 ports can be used for standard DS1 service delivery to customers or they can be used to connect traditional DS1 elements to the Broadband Loop Carrier network.
