Easily accessed and widely available language interpretation services are provided in a public switched telephone network by a common platform adjunct which automatically connects an interpretation services subscriber with a selected language interpreter associated with a language interpretation platform in the network. A subscriber dials, for example, an international telephone number which includes a code indicating that the call is an international call, a country code, a city code, and a local destination number. The ANI of the subscriber is detected and the call is routed to the adjunct which further verifies and validates the subscriber. The adjunct places a call through the public switched telephone network to the language interpretation platform. The call is answered either by an automatically preselected interpreter or by a human operator who causes the call to be manually transferred to a desired interpreter. The international call is completed to the destination and the calling subscriber, the interpreter, and the called party are bridged together. |

DETAILED DESCRIPTION FIG. 1 shows an example of a public switched telephone network architecture which may be used to implement various examples of this invention. FIG. 1 includes a schematic diagram of representative portions of a typical telecommunications network which includes a long distance public switched telephone network provided by a long distance carder such as AT&T. As shown in FIG. 1, entry into the long distance network is from a local public switched telephone network provided by a local exchange carder (LEC) such as one of the Regional Bell Operating Companies. In this example, the long distance public switched telephone network implements a language interpretation service in accordance with the invention, as described in more detail below. The language interpretation service could also be provided in one or more of the local public switched telephone networks such as those by which telephone customers typically gain access to long distance telephone networks. The network shown in FIG. 1 includes a local public switched telephone network 10 which provides local telephone service to a number of telephone customers. One of those customers is a language interpretation service subscriber 12 shown in FIG. 1. The subscriber 12 is connected to the network 10 by a suitable subscriber line 14 which may provide a voice circuit and suitable signaling capability, such as dual tone multiple frequency (DTMF) signaling capability. The network 10 is connected to an originating toll switch 16 in the long distance network by means of a suitable trunk connection 18. A line 20, which may be configured to operate as a primary rate interface (PRI), connects the switch 16 to a teleconference bridge 22 which will be used to create a conference between the subscriber 12, an interpreter, and a called party. The bridge 22 is connected to a common platform adjunct 24 by means of a suitable line 26. The adjunct 24 is a computer which effectuates the routing of calls through the network to connect the subscriber 12 with a called party and a language interpretation system in the network
