Abstract
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.
