Abstract
A critical assured service that includes a network management system and an A/B switch. The A/B switch having at least four ports with a first port being connected to the network management system over a dedicated line. The A/B switch sending and receiving messages and/or signals from the network management system over the first dedicated line. The A/B switch automatically switching telephone service from a first point of presence to a second point of presence after the A/B is signaled that the first point of service is inoperable.
Claims20
An apparatus comprising:
- a network management system;
- and
- an A/B switch for sending and receiving signals to and from the network management system over a dedicated line, the A/B switch comprising:
- a first port connected to a primary path to a first point of presence, the primary path including a connection between the first point of presence and a first router associated with the network management system,
- a second port connected to a secondary path to a second point of presence, the secondary path including a connection between the second point of presence and a server, the server connected to a second router associated with the network management system, and
- a third port connected to the network management system via the dedicated line;
- wherein the A/B switch is further for:
- switching telephone service from the first point of presence to the second point of presence after being signaled that the first point of presence is inoperable, and
- switching telephone service from the second point of presence to the first point of presence after being signaled that service to the first point of presence is restored;
- and
- wherein the network management system is for sending a command to the server when the first point of presence is inoperable, the command instructing the server to update routing translation tables of a specified group of phone numbers in a switching network to identify the second point of presence instead of the first point of presence so as to direct all internal and external incoming calls to the second point of presence along the secondary path.
8 more elements
A method comprising:
- upon receiving a signal that a first point of presence is inoperable:
- switching communication access, by an A/B switch, from a primary path to the first point of presence to a secondary path to a second point of presence, wherein the primary path connects a first port of the A/B switch to the first point of presence and connects a first router associated with a network management system to the first point of presence, and wherein the secondary path connects a second port of the A/B switch to the second point of presence and connects a server to the second point of presence, the server connected to a second router associated with the network management system;
- and
- sending a command from the network management system to the server, the command instructing the server to update routing translation tables of a specified group of phone numbers in a switching network to identify the second point of presence instead of the first point of presence to direct all internal and external calls to the second point of presence along the secondary path;
- and
- upon receiving a signal that the first point of presence is operational, switching communication access, by the A/B switch, from the second point of presence to the first point of presence.

An apparatus comprising:
- a network management system;
- and
- a switch for sending and receiving signals to and from the network management system over a dedicated line, the signals including an auto-ping signal for continuously monitoring a first point of presence to determine if the first point of presence is inoperable, the switch comprising:
- a first port connected to a primary path to the first point of presence, the primary path including a connection between the first point of presence and a first router associated with the network management system,
- a second port connected to a secondary path to a second point of presence, the secondary path including a connection between the second point of presence and a server, the server connected to a second router associated with the network management system, and
- a third port connected to the network management system via the dedicated line;
- wherein the switch is further for switching telephone service from the first point of presence to the second point of presence after being signaled that the first point of presence is inoperable, and
- wherein the network management system is for sending a command to the server when the first point of presence is inoperable, the command instructing the server to update routing translation tables of a specified group of phone numbers in a switching network to identify the second point of presence instead of the first point of presence so as to direct all internal and external incoming calls to the second point of presence along the secondary path.
