6440-01 Blade - Gigabit Optical Ethernet Transport
The 6440-01 Optical Packet Transport blade and BLC 6440-01 Assembly provide Gigabit Ethernet transport and direct next generation softswitch connection capability for the BLC 6000 Broadband Loop Carrier system. All voice traffic in a BLC 6000 system is carried as VoIP with MGCP signaling. The 6440-01 Blade is a high performance, fully capable Ethernet switch with 10 Gigabit Ethernet ports < 4 optical and 6 copper. Each blade also has 8 DS1 ports.
The 6440-01 supports Transparent Circuit Emulation Service by transporting the whole DS1 circuit through the network. This can either be synchronized to the network timing or operate with independent clocking. The 6440-01 can also cross-connect and transport individual DS0 circuits over the BLC 6000 IP network. In this mode, a DS0 circuit from multiple customers can be assigned to a DS1 connection headed either to the local Class 5 switch, to the Digital Access Cross-connect private line network or to support special services converters such as Enterprise Business (Nortel P-phone) Service.
The 6440-01 Blade can be deployed standalone as the BLC 6440-01 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 6440-01 Assembly may 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 6440-01 Blade and BLC 6440-01 Assembly are designed for a wide range of network applications. The flexibility of Ethernet switching allows any port to be used for any service or transport. The 4fiber Gigabit Ethernet ports, when 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 6440-01 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 tags 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 can also be configured for MLPPP and used as part of the protected feeder network for remote terminals over copper feeder plant for voice and Internet data services.
Direct Network Connection to Next Generation Softswitches The 6440-01 Blade and BLC 6440-01 Assembly can be used in the central office for seamless network connection to softswitch platforms. Any of the Ethernet ports can be used for this purpose. BLC 6000 networks ease the circuit-to-packet transition and yield additional cost savings in the access network by eliminating the Class 5 interfaces on the loop carrier side. The 6440-01 provides the protected feeder network transport required to sustain voice calls in the event of single network faults.
6640-01 Blade - Subscriber Trunk Gateway TR-08/GR-303 Interface and GigE 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.
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 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.
6660-01 Blade - Emergency Stand Alone
The 6660-01 Emergency Stand Alone Blade and BLC 6660-01 Assembly provide for local dialing to Emergency Service facilities and calls between local POTS subscribers during network outages. In ESA enabled networks, a loss of connectivity to the local digital switch does not prevent local calling for POTS subscribers. All voice traffic in a BLC 6000 system is carried as VoIP with MGCP signaling.
The Emergency Stand Alone feature takes advantage of the ability of POTS endpoints to communicate directly to one another under the control of directory services managed ESA blades. ESA blades may be deployed in remote CO facilities. They can manage all local calls to any emergency calling facility within the local calling area and can manage any local calls between residences and businesses within the local calling area.
ESA operation is controlled by a subscriber database for managing calls when the network is partitioned and/or separated from the local digital switch (Class 5 switch or softswitch, for example). The subscriber database enables the Telco to configure a dialing plan for the subscribers under control of the ESA system. These dial plans may range from very simple to more complicated numbering schemes, as required by the regional dialing requirements. Emergency services may be enabled using global hunt groups for emergency number dialing. Global hunt groups require minimal configuration in the subscriber database. Support for multiple local hunt groups allows one ESA system to manage several regions with unique emergency services per region.
Other ESA features available during network outages include limited call features such as Caller ID, Call Waiting and 3 Way Calling. The Telco provider may also configure verbal announcements to give subscribers more informative messages for commonly dialed numbers and prefixes that are not available during a network outage.
In addition to the directory services features, the ESA blade provides Gigabit Ethernet transport capability for the BLC 6000 Broadband Loop Carrier system.
