Abstract

A communication control system capable of lessening burden (load) of the repeater and reducing the number of development steps of the system. Data of the ATM standard delivered to an ATM/1394 repeater 3 through an ATM network 2 from an ATM terminal 1 is converted into data of the IEEE 1394 standard by an ASEL 31. The data thus obtained is transmitted to a 1394 terminal 4. The data of the IEEE 1394 standard transmitted to the 1394 terminal 4 is converted into data of the ATM standard by an ASEL 32.

Claims

1. A communication control equipment adapted for carrying out transmission of data transmitted from a first terminal to a second terminal through a repeater and to carry out transmission of data transmitted from the second terminal to the first terminal through the repeater, thus to control communication between the first terminal and the second terminal,

wherein the repeater comprises

first converting means for converting data of a first transmission standard transmitted from the first terminal into data of a second transmission standard, and

second converting means for converting data of the second transmission standard transmitted from the second terminal into data of the first transmission standard, and

wherein the second terminal comprises

third converting means for converting the data of the second transmission standard which has been caused to undergone transmission from the repeater into data of the first transmission standard, and

fourth converting means for converting predetermined data of the first transmission standard into data of the second transmission standard.

2. A communication control method for carrying out transmission of data transmitted from a first terminal to a second terminal through a repeater and to carry out transmission of data transmitted from the second terminal to the first terminal through the repeater, thus to control communication between the first terminal and the second terminal,

wherein processing procedure by the repeater comprises

a step of converting the data of a first transmission standard transmitted from the first terminal into data of a second transmission standard to carry out transmission thereof to the second terminal, and

a step of converting the data of the second transmission standard from the second terminal into data of the first transmission standard to carry out transmission thereof to the first terminal, and

wherein a processing procedure by the second terminal comprises

a step of converting the data of the second transmission standard which has been caused to undergo transmission through the repeater into data of the first transmission standard, and

a step of converting pre determined data of the first transmission standard into data of the second transmission standard to carry out transmission thereof to the repeater.
