An apparatus (D) is dedicated to processing E1 data frames in communications network equipment (ETPL) including at least one E1 line interface unit (LIU1). The apparatus (D) includes a processor adapted, on receiving from at least one E1 interface unit (LIU1) 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.
1. Switching equipment apparatus for use in a communications network for processing E1-type data frames, the switching equipment:
comprising an interface that receives at least one E1-type data frame addressed to a given E1 destination port; and
a processor that groups at least some of said E1-type data frames to constitute at least one group of at most n E1-type data frames, where the at most n E1-type data frames is grouped based on a common Ethernet destination port providing access to a respective E1 destination port of each E1-type data frame;
associates with each group a control header comprising data that represents the group; and
encapsulates the E1-type data frames of each group and the associated control header in a payload data field of an Ethernet frame to send the Ethernet frame to said common Ethernet destination port; and
wherein the respective common Ethernet destination port provides access to the plurality of destination E1 ports.
