EAC-C2C

EAC-C2C is a submarine telecommunications cable system interconnecting several countries in Asia, the Pacific, and the United States. It is a merger of the former EAC (East Asia Crossing) and C2C cable systems. The merger occurred in 2007 by Asia Netcom, and the cable system is now owned/operated by Pacnet. Pacnet was acquired by the Australian telecommunications company Telstra in 2015.

The EAC portion of the cable system includes:

Landing points:

Length: 19,500 kilometers

Capacity: 160 Gbit/s - upgradeable to 2.5 Tbit/s

Technology: DWDM (dense wavelength-division multiplex)

The C2C portion of the cable system comprises three rings:

The landing points on each ring are as follows:

Dolby Digital Plus

Dolby Digital Plus, also known as Enhanced AC-3 (and commonly abbreviated as DD+ or E-AC-3, or EC-3) is a digital audio compression scheme developed by Dolby Labs for transport and storage of multi-channel digital audio. It is a successor to Dolby Digital (AC-3), also developed by Dolby, and has a number of improvements including support for a wider range of data rates (32kbit/s to 6144kbit/s), increased channel count and multi-program support (via substreams), and additional tools (algorithms) for representing compressed data and counteracting artifacts. While Dolby Digital (AC-3) supports up to 5 full-bandwidth audio channels at a maximum bitrate of 640kbit/s, E-AC-3 supports up to 15 full-bandwidth audio channels at a maximum bitrate of 6.144 Mbit/s.

The full set of technical specifications for E-AC-3 (and AC-3) are standardized and published in Annex E of ATSC A/52:2012, as well as Annex E of ETSI TS 102 366 V1.2.1 (2008–08), published by the Advanced Television Systems Committee.
