ABSTRACT:
A communications network has a packet assembler/disassembler (PAD) 25 accessed from one or more nodes 21. Short delay limits can be met by creating composite packets at the nodes; these carry information for more than one call. Composite packets are transmitted to the PAD, disassembled and reassembled into composite packets each addressed to a single destination node. A call is allocated one or more octets at a given location in packets having a given connection number. Octets are handled by the PAD according to the connection number of their packet and their location in the packet.
