8. 8 Cabled Products T1 - A term for a digital carrier facility used to transmit a DS1 formatted digital signal at 1.544 Mbps. It is primarily used in the United States & Canada. E1 - A wideband digital interface operating at 2.048 Mbps, as defined by the ITU recommendations G.703 and G.704. Generally available outside North America. DS-3, the signal in the T-3 carrier, carries a multiple of 28 DS1 signals or 672 DS0s or 44.736 Mbps E3 - carries 16 E1 signals with a data rate of 34.368 Mbps

9. 9 Cabled Products... ATM - form of cell switching intended to carry a variety of data traffic, referred to cell relay or fast packet switching. Runs as a layer on top of SONET as well as on top of other technologies. SONET - Synchronous Optical NETwork. Includes a set of signal rate multiples for transmitting digital signals on optical fiber. The base rate (OC-1) is 51.84 Mbps. OC-2 runs at twice the base rate, OC-3 at three times the base rate, and so forth. Planned rates include OC-1, OC-3 (155.52 Mbps), OC-12 (622.08 Mpbs), and OC-48 (2.488 Gbps).
