Method and apparatus for providing virtual facility communication service

A system for accessing services of a main location private branch exchange by a terminal at a remote location, comprising:

• a concentrator at said remote location for unformatting an Internet formatted message transmitted from said main location private branch exchange to said remote terminal;
• and
• a public network for connecting the message from the concentrator to the main location private branch exchange via a LAN interface;
• wherein in the event of an Internet failure, the concentrator receives an analog portion of said message directly from the main location branch exchange.

A system for accessing services of a main location private branch exchange by a terminal at a remote location, comprising:

• a concentrator at said remote location for formatting an Internet provider message, said concentrator being connected to said remote terminal;
• a public network;
• a connection link connecting said concentrator to said public network;
• and
• an Internet interface connecting said pubic network to said main location private branch exchange via a LAN interface,
• wherein in the event of an Internet failure, the concentrator transmits an analog portion of said message directly to the main location branch exchange.

A method for accessing services of a main location private branch exchange by a terminal at a remote location, comprising:

• (a) formatting an Internet provider message at a concentrator at said remote location when said remote terminal goes off hook;
• (b) routing the formatted Internet provider message over a path including a connection link, a public network and an Internet interface;
• (c) unformatting the Internet provider message;
• and
• (d) transmitting the unformatted Internet provider message to the main location private branch exchange via a LAN interface,
• wherein in the event of an Internet failure, transmitting an analog portion of said message from said remote terminal directly to the main location branch exchange via an analog connection.
