1. A terminal unit comprising:
- a general-purpose modular jack capable of accommodating any one of a plurality of kinds of modular plugs;
identifying means for identifying the kind of the modular plug connected to said modular jack;
storing means for storing a plurality of protocols each corresponding to a respective kind of modular plug; and
protocol converting means for reading, based on an output of said identifying means, a matching protocol that matches the kind of the modular plug connected to said modular jack, and then setting said matching protocol as a protocol of said terminal unit.

Abstract
A terminal unit of the present invention and applicable to a wired services network distinguishes two or more different kinds of plugs possibly connected to its general-purpose modular jack, reads a particular protocol matching the plug out of its storage, and then sets the protocol as its own protocol. Therefore, a plurality of data terminals each having a particular protocol can share a single terminal unit. In addition, a protocol adequate for a desired data terminal can be automatically set. This enhances the convenient use of terminal equipments.
