Definitions
- Communication line 7 is a switched carrier inbound line which carries replies from terminals 1 to 4 to the CPU 5. Each terminal sends a response to CPU 5 via line 7 when it detects its address in a polling frame sent by
- a transmission from facsimile machine 42 is combined with polling frames from CPU 41 by communication apparatus 43, transmitted over the network and separated by communication apparatus 47 into respective data streams and supplied to facsimile machine 48 and control unit 49
- a period of flags 59 is replaced with facsimile data 60 from facsimile machine 42 by communication apparatus 43
- the combined polling and facsimile data is transmitted over the network in the normal way to communication apparatus 47.
- Communication apparatus 47 extracts the facsimile message 63, removes start and stop codes 61 , 62 and sends the facsimile message 63 to facsimile machine 48.

Abstract
Méthode pour transmettre des données secondaires (63) via une liaison (44, 45, 46) qui transmet des blocs de données primaires (57) en un flux de données entre une station émettrice (43, 47, 52) et une station réceptrice (43, 47, 52). Les données secondaires (63) sont mises en forme selon un protocole différent de celui utilisé pour les données primaires et sont insérées entre les blocs de données primaires. A la station réceptrice (43, 47, 52) les données secondaires sont extraites et le flux de données est rétabli dans sa forme originale. Le dispositif permettant d'appliquer cette methode se compose d'accès pour interfaces (70, 71) et d'une première interface d'entrée/sortie (73) interconnectée via un commutateur d'interconnexion (72). Une UC (74) fournit à la première interface d'entrée/sortie les données secondaire devant être insérées entre les blocs de données primaires et acheminées via le commutateur d'interconnexion (72) à un accès d'interface (70, 71). Un moyen contrôleur de séquences (75) surveille l'UC et veille à ce que le commutateur d'interconnexion (72) réalise une connexion directe entre les accès d'interface (70, 71) lorsque l'UC est inactive.
