Apparatus and accompanying methods for use therein for implementing an integrated, virtual office user environment, through an office server(s), through which a remotely stationed user can access typical office network-based applications, including e-mail, file sharing and hosted thin-client programs, through a remotely located network, e.g., WAN, connected web browser. Specifically, a front end, namely a service enablement platform (SEP), to one or more office servers on a LAN is connected to both the WAN and LAN and acts both as a bridge between the user and his(her) office applications and as a protocol translator to enable bi-directional, web-based, real-time communication to occur between the browser and each such application. The SEP translates user input originating from the browser into application-specific protocols and applies a result to a corresponding office application server.

Apparatus and accompanying methods for providing, through a centralized server site, a secure, cost-effective, web-enabled, integrated virtual office environment remotely accessible through a network-connected web browser

During initial operation, the SEP, operating under a default profile, establishes, over an analog connection to the WAN, a management session with the site to obtain customer WAN access information, then tears down the analog connection and establishes a broadband WAN connection through which the SEP re-establishes its prior session and obtains a client certificate and its customized profile. The SEP then re-initializes itself to that particular profile.

Apparatus for an improved ISDN terminal adapter (5) and accompanying methods for use therein. The adapter provides automatic ISDN switch detection, automatic SPID configuration, baud rate unblocking and automatic data compression. Specifically, the adapter automatically detects a type of ISDN switch (480) to which the adapter is connected by analyzing D-channel initialization messages which are received by the adapter from the switch as well as specific responses to ISDN messages sent by the adapter. The switch type value is then used, during SPID determination, in conjunction with a telephone area code of the user, to access an internal database (435) of predefined SPID formats, referenced in terms of particular telephone service areas and switch types, to access the possible SPID format(s) for the ISDN switch. Firmware (460) executing within the adapter, in conjunction with software executing within the DTE, forms one of more SPID(s) appropriate for the switch, queries the switch with each of these SPIDs to select and verify a correct SPID from those formed, and, if necessary, further refine and update the switch type previously determined.

A data communication system referred to as an Asynchronous/Synchronous Converter is provided to facilitate the communications between a data terminal equipment (DTE) device using the asynchronous communication port, and a dial-up router located in a digital network. When running a dial-up TCP/IP program over the asynchronous port, DTEs use a protocol called Asynchronous Point-to-Point Protocol (Asychronous PPP). On the other hand, dial-up routers usually support Synchronous PPP. The data communication system of the invention connects the DTE to the digital network and ultimately to the dial-up router and provides two way conversion between Asynchronous PPP and Synchronous PPP that is transparent to both the DTE and the router. This two way conversion is enabled in part by the converter intercepting and storing certain link control protocol (LCP) packets and using data in those packets to effect a translation.
