IETF RFC 5462 - Multiprotocol Label Switching (MPLS) Label Stack Entry: "EXP" Field Renamed to "Traffic Class" Field
February 1, 2009 - IETF

The early Multiprotocol Label Switching (MPLS) documents defined the form of the MPLS label stack entry. This includes a three-bit field called the "EXP field". The exact use of this field was not defined by these documents, except to state that it was to be "reserved for experimental use"....

CEI EN 62026-7 - Low-voltage switchgear and controlgear - Controller-device interfaces (CDIs) Part 7: CompoNet
September 1, 2013 - CEI

This part of IEC 62026 specifies an interface system providing bit-level and word-level communication between a controller and control circuit devices such as sensors, actuators, and switching elements. The interface system uses cabling with round or flat profiles containing a two conductor...

ATIS T1.TR.27 - Echo Cancelling
November 1, 1993 - ATIS

Echo cancellers are adaptive signal processors used to control echo; they are expected to replace echo suppressors in modern telecommunication networks. Echo cancellers are increasingly present on nearly every long distance connection and may be encountered singly or in tandem on a given...
