BLC 6000 Blades

The BLC 6660 Emergency Stand Alone (ESA) blade provides for local dialing to emergency service facilities and allows calls between local Occam POTS subscribers during network outages. In ESA enabled networks, a loss of connectivity to the local telephone switch does not prevent local calling for POTS subscribers who have been isolated.

The ESA 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 centrally or in remote CO facilities. They can manage all local calls to any emergency calling facility and 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). The subscriber database enables a service provider to configure a dialing plan for the subscribers under control of the ESA system. These dial plans can range from very simple to more complicated numbering schemes, as required by the regional dialing requirements. Emergency services can 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. Occam provides an API to simplify populating the subscriber database.

Other ESA features available during network outages include advanced call features such as caller ID, call waiting and 3-way calling. The service provider can also configure verbal announcements to give subscribers informative messages for commonly dialed numbers and prefixes that are not available during a network outage.

NOTE: ESA feature sets may differ when configured for use with MGCP or SIP VoIP on BLC POTS, Active Ethernet ONT POTS or GPON ONT POTS endpoints. In some ESA configurations an ARP Reply Gateway may be required to provide local calling. Contact Occam for specific configuration information.

T1/DS1 Services

In addition to the emergency stand alone features, the BLC 6660 blade has eight T1 ports that support transparent circuit emulation service (Occam CES). This service can either be synchronized to the network timing or operate with independent clocking.

Common OS Enhances Blade Operation and Service Management

Like all BLC 6000 blades, the BLC 6660 features OccamOS, a common operating system that spans the entire range of BLC 6000 copper, Gigabit Ethernet and GPON products to provide consistent and uniform system and service attributes. This OS integrates a wide range of Occam copper and optical broadband technological advancements including the company’s patented IP Security Management (IPSM), which allows for dynamic, “hands free” network security.

OccamOS also offers excellent tools to identify and troubleshoot Internet, voice and IPTV delivery problems including a full set of notification events, statistics and service assurance tools that allows for dynamic monitoring of any IPTV stream at any point in the network. And Ethernet Protection Switching (EPS) delivers “five nines” network availability, flexible network topologies and use of all network bandwidth through traffic load balancing during normal operation.

Multiple Applications

The BLC 6660 Emergency Stand Alone blade delivers two applications, including:

• Local telephone and emergency service during network outage
• Transparent circuit emulation service (Occam CES)
