PROBLEM TO BE SOLVED: To enable use of ISDN and use of a TA of BRI in the case of changing from the ISDN to ADSL. SOLUTION: An ADSL communication installation which performs communication of ADSL data is characterized by installing an IP data INF 101, an ISDN data INF 201, an interleave BUFF 103 which is in in-office ADSL and performs demultiplexing of IP data to interleave BUFF of ADSL data, a high-speed BUFF 202 which is in the in-office ADSL and performs demultiplexing of ISDN data to high-speed BUFF of the ADSL data, an ADSL termination 104 which is in the in-office ADSL and performs ADSL modulation and demodulation of the ADSL data which are subjected to demultiplex to an ADSL line, an LANINF 115 which is in in-home CPE, a BRIINF 205 which is in the in-home CPE, an interleave BUFF 113 which is in the in-home CPE and performs demultiplexing of the IP data to the interleave BUFF of the ADSL, a high-speed BUFF 203 which is in the in-home CPE and performs demultiplexing of the ISDN data to the high-speed BUFF of the ADSL data, and an ADSL termination 112 which is in the in-home CPE and performs ADSL modulation and demodulation of the ADSL data which were subjected to demultiplex to the ADSL line.
