ABSTRACT:
A device is for communication between a digital adapter linked to an exchange by means of a digital interface and an analog adapter linked to an exchange by means of an analog interface, said exchanges being linked by means of a telecommunications network. Digital information from the digital adapter is sent to the analog adapter, and vice versa, in digital form without emulating an analog signal.
