| Acronym | Description |
|---|---|
| 10/100 | indicates that the interface on the equipment can connect to either 10Base-T or at 100Base-T device. |
| 10-Base-2 | 10-Base-2 IEEE 802 3 specification, similar to Ethernet, using thin coaxial cable that runs at 10 Mbps, with a maximum distance of 185 meters per segment. Also known as Thin Ethernet or Thinwire Ethernet.. |
| 10-Base-5 | 10-Base-5 is also called Thick Ethernet and ThickWire. Connections are coaxial and operate at rates up to 10 Mbps. |
| 10Base-F | A physical layer communication specification for 10Mbps, baseband data transmission over a fiber-optic cable. |
| 10Base-T | IEEE 802.3 specification, using unshielded twisted-pair cabling and running at 10 Mbps. |
| 100Base-T | An Ethernet standard running at 100 Mbps It uses exactly the same CSMA/CD (Carrier Sense Media Access with Collision Detection) method as 10-BaseT for sharing the physical network medium between devices. Also known as Fast Ethernet. Three variants of 100Base-T exist: l00-Base-TX runs on 2 pairs from a category 5 Unshielded Twisted Pair (UTP) cable; 100Base-T4-runs on 4 pairs from a category 3 or better UTP cable, and 100-Base-FX-runs on optical fiber. |
| 100BaseTX | is the specification that describes how to run 100 Mbps Fast Ethernet over Category 5 Unshielded Twisted Pair. Catagory 5 UTP is the most popular type of cabling used in LANs today. |
| 10 GbE | Ten Gigabit (10,000,000,000 bits (10 billion)) Ethernet |
| 100VG-AnyLan | Another Ethernet standard running at 100 Mbps. In contrast to 100Base-T, 100VG was designed as a direct replacement for 10BaseT Ethernet that could run on the same category 3, 4, or 5 UTP cabling infrastructure in the same configuration—VG stands for "voice grade" and refers to the category 3 cable that can be used. It uses a completely different method from Ethernet—Demand Priority—to share the network medium between devices. |
| 1822 | Historic term which refers to the original ARPANET host-to-IMP interface. The specifications for this were given in BBN report 1822. |
| 1U | is equal to 1.75 inches. The "U" increment is a common data communications term to specify the height in a rack space that will be required. |
| 2B+D | The Basic Rate Interface (BRI) in ISDN A single ISDN circuit divided into two 64 kbps digital channels for voice or data and one 16 kbps channel for low speed data (up to 9,600 baud) and signaling. 2B+D is carried on one or two pairs of wires depending on the interface, the same wire pairs that today bring a single voice circuit into your home or office. See ISDN. |
| 23B+D | In ISDN, also known as the Primary Rate Interface. A circuit with a wide range of frequencies that is divided in twenty-three 64 kbps paths for carrying voice, data, video, or other information simultaneously It bears a remarkable similarity to today’s T1 link, except that T1 carries 24 voice channels. In ISDN, 23B-i-D gives twenty-three channels and one D channel. for out of band signaling. However, in T1, signaling is handled in band. See ISDN. |
| 2 Megabit Trunk | The basic digital rate in most of the world, outside of North American and Japan. It consists of 32 - 64 kbps time slots, 0-31. Time slot 0 is reserved for synchronization, and time slot 16 is reserved for signaling. |
| 30 Channel Trunk (E1) | A circuit running at 2.048 mbps, and carrying 32 DS0s. Generally, only 30 of the 32 are available for customer data, the others are reserved for signaling and synchronization. |
| 3/1/0 DACS | A digital access & cross connect system that can divide a DS-3 signal to the individual DS-1 or DS-0 level. |
| 6B0NE | The Internet’s experimental IPv6 network. |
| 802.x | The set of IEEE standards for the definition of LAN protocols. |
| 802.11a | IEEE specifications for a wireless LAN 5 GHz with data rates to 54 Mbps |
| 802.11b | IEEE specifications for a wireless LAN at 2.4 GHz with data rates to 11 Mbps |
| 802.11g | IEEE specifications for a wireless LAN at 2.4 GHz with data rates to 54 Mbps |
| 802.11n | IEEE amendment of the 802.11 standard which defines MIMO operation on the physical lay and incorporates improvements on the MAC layer. |
| 822 | Short form of "RFC 822." Refers to the format of Internet style e-mail as defined in RFC 822. |
