    • PURPOSE:To make possible the transmission and reception of signal units(MSU) between signal stations which are different in station code length. CONSTITUTION:A station code discrimination part 21a discriminates the station code length of a signal station which sends a signal of routing information included in an MSU arriving through an input link on the basis of the routing information. A station code conversion part 21b converts the station code included in the MSU into an internal station code (or the longest station code or 15-bit station code) on the basis of the station code length. A routing part 22 performs a routing process for determining the outgoing route of the MSU with the internal station code (the longest station code or 14-bit station code). A station code length discrimination part 23c discriminates the station code length of the signal station from which the MSU is sent on the basis of the routing information obtained by the routing process and an actual station code conversion part 23d converts the internal station code (the longest code or 14-bit station code) into an actual station code on the basis of the station code length and sends it out.

    • PURPOSE:To receive book information at a subscriber side and to automatically correct the telephone number of a subscriber in altering his number recorded in an auto dial number recording area by transmitting telephone number information including the telephone number and new altered one of the subscriber who is altering the old telephone number to the subscriber side from an exchange side through a digital subscriber line. CONSTITUTION:The auto-dial automatic outgoing is executed from a terminal 2. An exchange 1 receives a transmitted telephone number 3a and analyzes it. When it is found to be altered, the exchange 1 reports the telephone numbers 3a and 3a' of a terminal 3 to the terminal 2, which recognizes that the terminal 3 is altering its telephone number with the aid of a means 2c receiving and recognizing digital information. Then a collating means 2d collates the received and recognized telephone number 3a of the terminal 3 with the telephone number 3a of the terminal 3 recorded in the auto dial number recording area 2b of its own terminal. If they are the same with each other, the telephone number 3a of the terminal 3 recorded in the recording area 2b of its own terminal is rewritten to the telephone number 3a' of the terminal 3a, which is altered.
