ABSTRACT:
A subscriber terminal installation for an asynchronous network, the installation having a subscriber digital termination comprising a switching matrix and access modules each connected firstly to the switching matrix and secondly to an asynchronous optical interface. One of the access modules is connected to a network digital termination, while each of the other access modules is connected either to a terminal or else to a terminal adapter. A processor connected to the module processes signalling received or to be transmitted via the access modules. A terminal adapter comprises a multiplex adapter, a service adapter specific to a particular service, and a control circuit. The multiplex adapter is connected via a two-way asynchronous optical interface to an access module and via an up interface and a down interface to the service adapter, the up and down interfaces being asynchronous interfaces conveying cells.
