An apparatus (D) is dedicated to processing E1 data frames in communications network equipment (ETPL) including at least one E1 line interface unit (LIU). The apparatus (D) includes a processor adapted, on receiving from at least one E1 interface unit (LIU) at least one E1-type frame addressed to a given E1 destination port, to encapsulate that E1-type frame in a payload data field of an Ethernet frame in order to send it to an Ethernet destination port providing access to the given E1 destination port.

A video codec for a videophone terminal of an integrated services digital network. The codec is organized to receive firstly image signals from a television camera so as to transmit them, after compressing and encoding them, to a remote video decoding unit, via a digital transmission line, and secondly similarly-processed image signals via the digital transmission line, so as to decompress and decode them for a television screen receiver locally connected to the video codec. The video codec includes a processing unit, of the integrated circuit type, co-operating with a single external memory plane both to compress and encode data to be transmitted, and also to decompress and decode received data, with the assistance of internal operational components time shared so as to apply known methods to transmission and to reception.
