| 1.5-way paging |
Refers to guaranteed message receipt or advanced messaging, ensuring subscribers receive messages sent when they're out of range, but users cannot send text pages. Two-way paging allows users to send and receive. |
| 1.7-way paging |
A paging service that offers more than guaranteed messaging but not as much as full two-way paging. The subscriber has limited response messaging, such as canned messages, rather than the ability to create responses. |
| 100Base-FX |
IEEE 802.3 shorthand term for 100 Mb/s Fast Ethernet based on 4B/5B signal encoding over fiber optic cable. |
| 10Base2 |
IEEE 802.3 shorthand term for 10 Mb/s Ethernet based on Manchester signal encoding over thin coaxial cable. Also called "Thinnet" or "Cheapernet". |
| 10Base5 |
IEEE 802.3 shorthand term for 10 Mb/s Ethernet based on Manchester signal encoding over thick coaxial cable. Also called "Thicknet". |
| 10Base-F |
IEEE 802.3 shorthand term for 10 Mb/s Ethernet based on Manchester signal encoding over fiber optic cable. |
| 10Base-T |
IEEE 802.3 shorthand term for 10 Mb/s Ethernet based on Manchester signal encoding over category 3 or better twisted pair cable. |
| 10Broad36 |
IEEE 802.3 shorthand term for 10 Mb/s Ethernet on broadband cable. |
| 1Base5 |
IEEE 802.3 shorthand term for StarLAN at 1Mb/s data transfer rate. |
| 1G |
First generation. Refers to the first generation cellular phones that were analog-based technology. |
| 2.5G |
Second-and-a-half generation. Refers to the additional features and functionality added to digital cellular phones, such as Internet access and messaging. |
| 2G |
Second generation. Refers to the second generation cellular phones that introduced digital technology (CDMA, TDMA, and GSM). |
| 2-in-1 Handset |
The situation where a subscriber handset is acting as a remote handset to a base unit which provides a network connection. |
| 2-wire line |
The set of two copper wires used to connect a telephone customer with a switching office, loosely wrapped around each other to minimize interference from other twisted pairs in the same bundle. Synonymous with twisted pair. |
| 30 Channel Mux (Europe) |
A form of PCM multiplex equipment. 30 speech channels A-Law + 2 eight digit utility channels (32 timeslots in all) for a trans-mission rate of 2,048 Kbit/s. |
| 3G |
Third generation. Refers to the next generation of digital phone technology beyond the 2.5G technology. |
| 3-in-1 Wireless Communication |
Cellular phone systems that provide wireless telephony, Short Message Service, and Distpatch. |
| 4B/5B Code |
Scheme used to encode data for transmission in which 4-bit binary data values are encoded into 5-bit symbols for transmission across the network media. 4B/5B is used with Ethernet 100Base-TX and 100-Base-FX media systems. |
| 8B/10B Code |
Scheme used to encode data for transmission in which 8-bit binary data values are encoded into 10-bit symbols for transmission across the network media. 8B/10B is used with 1000Base-X Gigabit Ethernet media systems. |
| 8B6T |
Signal encoding method used with the 100Base-T4 Ethernet media system. |
