- ds1c — (communications) A DS level and framing specification for digital signals in the North American digital transmission hierarchy. A DS1C signal uses 48 PCM channels and has a transmission rate of 3.15 Megabits per second, twice that of DS1. DS1C uses two DS1 signals combined and sent on a 3.152 megabit per second carrier which allows 64 kilobits per second for synchronisation and framing using "pulse stuffing". The channel 2 signal is logically inverted, and a framing bit is stuffed in two out of three code words, resulting in 26-bit information units. The channels are interleaved and then scrambled by the addition modulo 2 of the signal with the previous bit. Finally the bit stream is combined with a control bit sequence that permits the demultiplexor to function by preceding each 52 bits with one DS1C framing bit. A series of 24 such 53-bit frames forms a 1272-bit "M-frame".

- v.10 — (communications, standard) An ITU-T recommendation on electrical characteristics for unbalanced double-current interchange circuits operating at data signalling rates nominally up to 100 kbps. This recommendation is also included but not published in ITU-T X series under alias number X.26. The circuit defined in this standard is used in other serial line standards such as EIA-232 and EIA-423, that implement single ended communication.
- v.11 — (communications, standard) An ITU-T recommendation on electrical characteristics for balanced double-current interchange circuits operating at data signalling rates up to 10 Mbps. V.11 is also included but not published in the as ITU-T X.27. V.11 is used in other serial line standards such as EIA-422 and EIA-485, that implement differential line communication.
- v.17 — (protocol, standard) An ITU-T modem protocol for 14400 bps half duplex communications with fall back to 12000 bps, 9600 bps and 7200 bps.
- v.21 — (protocol, standard) An ITU-T modem protocol for 300 bps two-wire full-duplex communications using Frequency Shift Keying modulation. All modern modems support both V.21 and the close variant, Bell 103.
- v.91 — (protocol) An all-digital version of the V.90 protocol, undergoing ITU-T approval.
- x.12 — (standard) The American equivalent of UN/EDIFACT and various other national and industry EDI messaging protocols. The first Y2K ready version of X.12 is version 4010.
- x.21 — (communications, standard) A digital signaling interface recommended by ITU-T that includes specifications for DTE/DCE physical interface elements, alignment of call control characters and error checking, elements of the call control phase for circuit switched services, data transfer at up to 2 Mbps, and test loops. 64 kbps is the most commonly used transfer rate.
- z180 — (processor) An 8-bit microprocessor, code compatible with the Zilog Z80 and based on a design from Hitachi which is in turn based on the Zilog Z80.
