Abstract

PURPOSE:To simplify the accommodation of an exchange and a host computer and to eliminate the need for a special interface by accommodating plural line interfaces of a host computer to a multiplex interface used in general. CONSTITUTION:A data terminal equipment 3 is accommodated to an exchange 1 and an exchange circuit 4 is connected to the multiplex interface 40 of the exchange 1. The exchange circuit 4 is connected to line channels 20-2n of a host computer 2. Further, protocol converting circuits 50-5n are provided corresponding to the channels 20-2n to the converting circuit 4 and the converting circuits 50-5n convert a signal inputted/outputted to/from the computer 2 to a signal accommodated to the exchange 1. The converted signal is multiplexed by a multiplex circuit 42, the signal is converted by a circuit 41 connected to the interface 40 of the exchange 1 and accommodated in the exchange 1 so as to simplify the accommodation of the exchange 1 and the computer 2.

Description

[Detailed description of the invention] (Technical field) The present invention relates to a host computer accommodation system.

(Prior Art) Conventionally, this type of host computer accommodation system has been implemented as shown in FIG. In FIG. 3, 1i [change machine,
2 is a host computer, and 10 to 1n are conversion circuits for connecting the exchange 1 and the host computer 2, which are provided corresponding to the host computer 20 line channels 20 to 2rl. This host computer computer 2 is, for example, a data terminal 3.
When the exchange 1 selects one of the empty ports 30 from among the host computer accommodation ports 30 to 3n,
It is connected to the host computer 2 via the conversion circuit 10, and the data terminal 3 is connected to the host computer 2.

However, in general, the host computer 2 has multiple line channels, and it is necessary to provide a conversion circuit for each channel, which makes the connection between the conversion circuit and the exchange complicated, increases the number of conversion circuits, and simplifies the Innotaface circuit. is required.

(Object of the Invention) An object of the present invention is to provide a conversion circuit which eliminates the above-mentioned drawbacks of the conventional converter and which facilitates connection between an exchange and a host computer.

(Structure of the Invention) According to the present invention, in a conversion circuit that connects an i-exchange capable of accommodating digital multiplexed signals and a host computer, the host copier side has an interface corresponding to the protocol processed by the host copier in correspondence with the line channel. and a host conobeater accommodation system characterized in that the exchange side is equipped with an interface to which digital multiplex signals can be connected, and the signals of multiple line channels input and output from the host computer are multiplexed and accommodated in the exchange. is obtained.

(Example) Next, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a block diagram of an embodiment of the present invention. In FIG. 1, 1 is an exchange, 2 is a host combination, 3 is a data terminal, and these are housed in the exchange 1. 4 is a conversion circuit of the present invention. Further, 40 is a multiplex interface 2 provided in the exchange 1, and in this example, it'x64K
This is a standard interface such as the so-called T1 interface in which a single bps a channel is multiplexed with 24 channels. The conversion circuit 4 multiplexes the signals from the host computer 2 and connects the signal to a multiplexing interface (for example, T1/TAFUS) of the exchange 1.

FIG. 2 is a block diagram of an embodiment of the conversion circuit 4 in FIG. It has a function of converting the output signal into a signal that can be accommodated in the exchange l. 50-5
The signals converted by n are multiplexed by a multiplexing circuit 42, and all signal conversion is performed by a circuit 41 so that the signals can be connected to a multiplexing interface (for example, T1 interface) 40 of the exchange 1, and the signals are accommodated in the exchange.

(Effects of the Invention) According to the present invention, multiple line interfaces of a host copier can be accommodated in a commonly used multiplexed interface, which simplifies the accommodation of AC/LA machines and host computers. There is no need to prepare a separate interface.
