ATIS 0100509.1995(S2018)

The purpose of this standard is to standardize the interface to packetized circuit multiplication equipment (PCME). PCME converts speech, voiceband data, facsimile, channel-associated (i.e. in-band) signaling, common channel signaling, video, and digital data information from channelized DS1 of Synchronous Optical Network (SONET) formats to LAPD-like frame format.
