There are two types of radio network currently in use around the world: the one-to-many (simplex communication) broadcast network commonly used for public information and mass-media entertainment, and the two-way radio (duplex communication) type used more commonly for public safety and public services such as police, fire, taxicabs, and delivery services. Cell phones are able to send and receive simultaneously by using two different frequencies at the same time. Many of the same components and much of the same basic technology applies to all three.

The two-way type of radio network shares many of the same technologies and components as the broadcast-type radio network but is generally set up with fixed broadcast points (transmitters) with co-located receivers and mobile receivers/transmitters or transceivers. In this way both the fixed and mobile radio units can communicate with each other over broad geographic regions ranging in size from small single cities to entire states/provinces or countries. There are many ways in which multiple fixed transmit/receive sites can be interconnected to achieve the range of coverage required by the jurisdiction or authority implementing the system: conventional wireless links in numerous frequency bands, fibre-optic links, or microwave links. In all of these cases the signals are typically backhauled to a central switch of some type where the radio message is processed and resent (repeated) to all transmitter sites where it is required to be heard.

In contemporary two-way radio systems a concept called trunking is commonly used to achieve better efficiency of radio spectrum use and provide very wide-ranging coverage with no switching of channels required by the mobile radio user as it roams throughout the system coverage. Trunking of two-way radio is identical to the concept used for cellular phone systems where each fixed and mobile radio is specifically identified to the system controller and its operation is switched by the controller.

In mathematics and computing, the hexadecimal (also base 16 or hex) numeral system is a positional numeral system that represents numbers using a radix (base) of 16. Unlike the common way of representing numbers using 10 symbols, hexadecimal uses 16 distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9, and "A"–"F" (or alternatively "a"–"f") to represent values 10 to 15.

Hexadecimal numerals are widely used by computer system designers and programmers because they provide a human-friendly representation of binary-coded values. Each hexadecimal digit represents four bits (binary digits), also known as a nibble (or nybble), which is 1/2 of a byte. For example, a single byte can have values ranging from 00000000 to 11111111 in binary form, which can be conveniently represented as 00 to FF in hexadecimal.

In mathematics, a subscript is typically used to specify the base. For example, the decimal value 41,427 would be expressed in hexadecimal as A1D316. In programming, a number of notations are used to denote hexadecimal numbers, usually involving a prefix or suffix. The prefix 0x is used in C and related programming languages, which would denote this value as 0xA1D3.

Hexadecimal is used in the transfer encoding Base16, in which each byte of the plaintext is broken into two 4-bit values and represented by two hexadecimal digits.

An off-premises extension (OPX), sometimes also known as off-premises station (OPS), is an extension telephone at a location distant from its servicing private branch exchange (PBX). An off-premises extension is generally used to provide employees with access to a company telephone system while they are out of the office.

Off-premises extensions are used in distributed environments, serving locations that are too far from the PBX to be served by on-premises wiring.

An OPX uses a conditioned wire pair that is usually used only for voice applications, while for data, a pair usually needs to be unconditioned. An alarm circuit is an unconditioned pair.

In Internet telephony, a VoIP VPN OPX may be implemented by connecting an extension over a virtual private networking connection, instead of connecting it directly to the local area network. As a host connected by a VPN appears as a part of the local area network, the off-premises extension appears to the IP-PBX as if it were on-site.

The yellow pages are telephone directories of businesses, organized by category rather than alphabetically by business name, in which advertising is sold. The directories were originally printed on yellow paper, as opposed to white pages for non-commercial listings. The traditional term "yellow pages" is now also applied to online directories of businesses.

In many countries, including Canada, the United Kingdom, Australia, and elsewhere, "Yellow Pages" (or any applicable local translations), as well as the "Walking Fingers" logo first introduced in the 1970s by the Bell System-era AT&T, are registered trademarks, though the owner varies from country to country, usually being held by the main national telephone company (or a subsidiary or spinoff thereof). However, in the United States, neither the name nor the logo was registered as trademarks by AT&T, and they are freely used by several publishers. This can sometimes be confusing as YP (AT&T), Yellow Pages Directory Inc and yellow pages are all similar in nature. To distinguish one Yellow Pages from another more accurately, the US trademark Office recently granted on Feb. 02, 2021 a trade mark for the company Yellow Pages Directory Inc to become the "Official Yellow Pages Directory."

A feature group, in North American telephone industry jargon, is most commonly used to designate various standard means of access by callers to competitive long-distance services. They defined switching arrangements from local exchange carriers central offices to interexchange carriers. These arrangements were described in an official tariff of the National Exchange Carrier Association, filed with the Federal Communications Commission (FCC).

While there are other feature groups for local access, the four common feature groups exist for access from the local subscriber to competitive long-distance carriers:

These Feature Group alternatives allowed the LEC's end users to make long-distance calls using the interexchange carrier's network, when non-stored program-controlled exchanges could not be modified to provide equal access. By the mid 1990s, Equal Access features in exchange software had rendered Feature Group D universally available in modern landline exchanges; the others are either used for calling card applications or are obsolete.

L2F, or Layer 2 Forwarding, is a tunneling protocol developed by Cisco Systems, Inc. to establish virtual private network connections over the Internet. L2F does not provide encryption or confidentiality by itself; It relies on the protocol being tunneled to provide privacy. L2F was specifically designed to tunnel Point-to-Point Protocol (PPP) traffic.
