Abstract
A host structure is provided for terminal adapters that are part of a distributed computer architecture. Each computer system is in turn connected to a number of synchronous or asynchronous terminals via the network and terminal adapters, each terminal adapter connected, on one hand, to the network and, on the other hand, to at least one terminal via a synchronous or asynchronous transmission link. The host structure can contain a number of adapter cards, each containing the electronic circuit of an adapter, and is composed of a first compartment with the adapter cards, and a second compartment with an equal number of connection cards. The connection cards each enable connecting a number of terminals to a particular adapter.

A host structure P for terminal adapters AD to AD15, to H that are part of a distributed computer architecture ARCH composed of a plurality of computer systems SI, SIS1, SISj, SAD1, SAD2, . . . SADj each connected via communication servers SERV, SERV1, SERVj1, SERVj2 to at least one network RE, with each computer system connected to a plurality of terminals T1, T2, T3 T4, T5, via the network RE and terminal adapters AD21, . . . , AD2p, ADj1, . . . , ADjp, AD1, . . . , AD15, AH, each of said terminal adapters being connected to the network and to at least one corresponding terminal via a transmission connection, said host structure containing a plurality of adapter cards, each with the electronic circuit of an adapter, physically independent from one another, wherein said host structure includes:
- a front side FAV permitting removal of the adapter cards AD1 to AD15, AH and a back side FAR permitting connection of each adapter card to the network and to the at least one corresponding terminal;
- a front compartment CAD including the front side with adapter cards parallel to one another;
- a back compartment CCT including the back side and connection cards, each one corresponding to an adapter card, and the number of connection cards is equal to the number of adapter cards;
- and
- wherein the two compartments are separated by a backplane assembly FP, with each adapter card having means of removal located on the side of the front and first means of connection connecting said adapter card to second means of connection for the connection card via the backplane assembly for connecting each card to the network;
- each connection card is equipped with third means of connection located on the side of the front for connecting the corresponding adapter card to the at least one corresponding terminal.
A host structure for networked terminal adapters that are part of a distributed computer architecture, comprising:
- a backplane assembly having a plurality of first interface elements on a first side and a plurality of second interface elements on a second side;
- a plurality of first circuit cards adapted for electrical connection with said plurality of first interface elements, said plurality of first circuit cards comprising at least one terminal adapter card and at least one hub card;
- a plurality of second circuit cards adapted for electrical connection with said plurality of second interface elements, said plurality of second circuit cards comprising a plurality of connection cards corresponding to said plurality of first circuit cards;
- and
- a plurality of cable interface elements disposed on said plurality of second circuit cards for electrically connecting said plurality of second circuit cards to a corresponding plurality of remote terminals.
