FIXED STATION INTERFACE FOR LEGACY BASE STATION EQUIPMENT
First Claim
1. A fixed station interface for a base station comprising:
- a plurality of interfaces configured to perform serial communication with the base station; and
circuitry configured toupload remotely via a web browser a set of instructions to operate the plurality of interfaces,determine an operational channel for a first interface of the plurality of interfaces to communicate with the base station,receive on the first interface, a message in a V.24 format that is supported by the base station and that is to be transformed into a BAHA format,determine portions of the received message that are to be discarded prior to transformation into the BAHA format, and portions of the received message that are to be maintained for transformation into the BAHA format, the discarded portions of the received message being portions that do not map into the BAHA format, and that have a fixed length, which is dependent on a type of the received message, andtransform only the maintained portions of the received message in the V.24 message format into the BAHA format, by mapping at least one of a first portion, a second portion, a third portion and a fourth portion of the maintained portions to corresponding portions of the message in the BAHA format.

Abstract
An interface device for provisioning Internet Protocol (IP) communications to be established for base station equipment that employ proprietary device specific protocols. A fixed station interface (FSI) translates between a V.24 High-Level-Data-Link Control (HDLC) protocols used for external data connections on base station equipment to a Voice-Over-Internet-Protocol (VOIP) open-standard protocol. Upon being deployed in First Responder communications networks (that use legacy base station equipment), the FSI provisions for the retention of existing installed base station equipment while providing a low cost solution to support VOIP communications interconnectivity and reliability, thereby enhancing the effectiveness and safety of the First Responder systems.

13. A method of operating a fixed station interface for a base station, the method comprising:
-
uploading remotely, via a web browser, a set of instructions to operate a plurality of interfaces of the fixed station interface; determining an operational channel for a first interface of the plurality of interfaces to communicate with the base station; receiving on the first interface, a message in a V.24 format that is supported by the base station and that is to be transformed into a BAHA format; determining portions of the received message that are to be discarded prior to transformation into the BAHA format and portions of the received message that are to be maintained for transformation into the BAHA format, the discarded portions of the received message being portions that do not map into the BAHA format, and that have a fixed length, which is dependent on a type of the received message; and transforming only the maintained portions of the received message in the V.24 message format into the BAHA format, by mapping at least one of a first portion, a second portion, a third portion and a fourth portion of the maintained portions to corresponding portions of the message in the BAHA format. - View Dependent Claims (14, 15, 16)

17. A non-transitory computer readable medium having stored thereon a program that, when executed by a computer, causes the computer to perform a method of operating a fixed station interface for a base station, the method comprising:
-
uploading remotely, via a web browser, a set of instructions to operate a plurality of interfaces of the fixed station interface; determining an operational channel for a first interface of the plurality of interfaces to communicate with the base station; receiving on the first interface, a message in a V.24 format that is supported by the base station and that is to be transformed into a BAHA format; determining portions of the received message that are to be discarded prior to transformation into the BAHA format and portions of the received message that are to be maintained for transformation into the BAHA format, the discarded portions of the received message being portions that do not map into the BAHA format, and that have a fixed length, which is dependent on a type of the received message; and transforming only the maintained portions of the received message in the V.24 message format into the BAHA format, by mapping at least one of a first portion, a second portion, a third portion and a fourth portion of the maintained portions to corresponding portions of the message in the BAHA format. - View Dependent Claims (18, 19, 20)
