System and method for providing competitive access telephone service for telephones connected to a remote terminal of the monopoly service provider
First Claim
1. In a local telephone network, a system for providing competitive access to a remote terminal connected to a plurality of lines, said remote terminal being controlled by a monopoly provider switch for controlling said plurality of lines at said remote terminal, said local network including a signaling network, said system comprising:
- a competitive access provider (CAP) switch, said CAP switch having facilities for remote terminals, said CAP switch being connected to said signaling network;
said remote terminal being connected to said CAP switch by one or more trunks;
said CAP switch having means for sending messages to said monopoly provider switch via said signaling network in order to control said lines served by said CAP switch; and
said monopoly provider switch including means for determining which switch serves a particular line, and means responsive to said messages from said CAP switch to control said remote terminal according to said messages.

Abstract
A system for providing a competitive access provider controls specific lines in a remote terminal connected to a monopoly service provider connected directly from the remote terminal to a competitive access switch. In order to control the line or lines in the remote terminal, the competitive access provider switch sends signals via a signaling network to the monopoly service provider. In this manner, a competitive access provider may control a plurality of lines in a remote terminal without having to change a physical plant other than directing one or more DS 1 s or other trunks from the remote terminal to a host digital terminal on the competitive access provider network.

6. A method for completing a call in a local switching network from a competitive access provider (CAP) switch to a remote terminal, said local switching network including at least one switch connected to said remote terminal, said remote terminal receiving operational commands exclusively from said switch, said competitive access provider (CAP) switch connected by one or more trunks to said remote terminal, said remote terminal being connected to a plurality of lines, and said local switching network including a signaling network to which both said switch and said CAP switch are connected, said method comprising the steps of:
-
receiving a call at said CAP switch for a predetermined line at said remote terminal; said CAP switch sending a signaling message over said signaling network to said switch to determine the state of said line at said remote terminal; said switch determining said state of said line and sending a status message to said CAP switch over said signaling channel; if said line is not busy, said CAP switch sending a signaling message to said switch to reserve facilities, including a channel on said one or more trunks,in order to set up a call path from said CAP switch to said remote terminal; and completing said call from said CAP switch to said remote terminal.

7. A method for completing a call in a local switching network from a remote terminal through a competitive access provider (CAP) switch, said local switching network including at least one switch connected to said remote terminal, said remote terminal receiving operational commands over a control channel exclusively from said switch, said competitive access provider (CAP) switch connected by one or more trunks to said remote terminal, said remote terminal being connected to a plurality of lines, and said local switching network including a signaling network to which both said switch and said CAP switch are connected, said method comprising the steps of:
-
receiving a call service request from a line at said remote terminal; said remote terminal sending a request over said control channel to said switch to determine which of said switch and said CAP switch serves said line; said switch determining that said line is served by said CAP switch and said switch sending a signaling message over said signaling network to said CAP; said remote terminal determining a destination directory number (DN) and sending said DN to said switch, which forwards said DN to said CAP switch over said signaling network; said CAP switch setting up a call path to said DN and sending a signaling message to said switch to reserve facilities, including a channel on said one or more trunks, in order to set up a call path from said DN to said remote terminal line; and completing said call from said DN through said CAP switch to said remote terminal line.
