PROBLEM TO BE SOLVED: To provide a radio communication unit which can perform communication by radio through bus wiring between an ISDN network and an ISDN apparatus. SOLUTION: Upon the receipt of voice data set with TEI from an ISDN network, a radio communication unit 10 converts ISDN protocol into Bluetooth protocol, which is then attached with an AM address and transmitted to a slave radio communication unit. Upon the receipt of data attached with an AM address and set with TEI from the radio communication unit 10, a radio communication unit 20-1 converts Bluetooth protocol into ISDN protocol, which is then transmitted to an ISDN apparatus 30-1. When the set TEI matches TEI transmitted from the radio communication unit 20-1, the ISDN apparatus 30-1 acquires voice data from the radio communication unit 20-1. |
