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.
Claims21
An apparatus comprising:
- a network management system;
- a switch having at least four ports, wherein a first port is 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, wherein a second port is 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, wherein a third port is connected to the network management system via a dedicated line;
- the switch for sending and receiving signals to and from the network management system over the dedicated line, the switch for:
- automatically switching telephone service from the primary path to the first point of presence to the secondary path to the second point of presence after being signaled that the first point of presence is inoperable;
- and
- the network management system 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.

A method comprising:
- a switch automatically switching communication access from a primary path to a first point of presence to a secondary path to a second point of presence when the first point of presence is inoperable,
- the primary path connecting a first port of the switch to the first point of presence and connecting a first router associated with a network management system to the first point of presence,
- the secondary path connecting a second port of the switch to the second point of presence and connecting a server to the second point of presence, the server connected to a second router associated with the network management system;
- the switch receiving a signal that the first point of presence is inoperable;
- and
- sending a command from the network management system 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 to direct all internal and external calls to the second point of presence along the secondary path.
