Abstract: An electronic communications recording system (20) comprises a packet data network (PDN) (22) configured to support a PDN protocol. A gateway (24) comprises at least one gateway input port which is connectable to a respective one of at least one communications carrier (No to Nn) carrying data relating to a plurality of communications events according to a respective carrier protocol type; and at least one PDN port connected to the PDN. The gateway is configured to translate data at said at least one input port from the respective carrier protocol type to PDN data in the PDN protocol. At least one communications event analyzer (26) is connected to the PDN and configured to receive as addressed destination at a service access point (19), translated PDN data associated with at least one predetermined port of said at least one gateway input port, to process the received PDN data and to extract from the received PDN data, communications event data relating to at least one communications event.

Abstract: A media gateway (34.2) comprises a line interface (54) comprising at least one input port, which is connectable to a time division multiplex (TDM) communications carrier. The at least one input port being configured to receive input data in at least one of a) clear channel data in a data carrier type and b) TDM framed in a primary rate carrier. The gateway comprises an extractor (66) for extracting the clear channel data and a formatter (64) for formatting the framed data. The gateway further comprises an interface (67) for making the extracted data and/or formatted data available as packet data network (PDN) data at a PDN output port of the gateway.
