Telecom Terms Glossary
Understanding Telecom
The telecommunications industry has evolved quickly over the last 40 years. New technologies, procedures, protocols, and standards have come and gone and wrapping your head around all of the various terms and abbreviations can be daunting.
We’ve compiled a list of common terms we use (we, as in Fidalia) that you may want to know as you work with us.
Of course, if there’s a term you don’t understand – or want to understand better – please let us know and we’ll happily explain it to you.
Access Point
A device that allows wireless devices to connect to a wired network using Wi-Fi.
Analog Telephone Adapter (ATA)
An ATA is a device that converts IP to analog signaling, allowing devices like fax machines and fire alarms to send calls over your internet connection. An ATA is most often used to allow traditional analog phones work with IP (VoIP) phone systems.
API (Application Programming Interface)
A set of protocols that allow different software systems to communicate with each other.
Auto-Attendant (Phone System)
An auto-attendant is a phone system feature that automatically answers incoming calls and routes them to the appropriate extension or department without human intervention. It typically provides a menu of options (e.g., “Press 1 for sales, press 2 for support”) to guide callers.
Backup Internet
The delivery of a secondary internet connection, designed to engage when the primary connection becomes unusable – either offline or severly degraded. The secondary connection (backup) engages seamlessly, using the same IP address of the primary connection.
Bandwidth
The maximum rate of data transfer across a network, typically measured in bits per second (bps).
BGP (Border Gateway Protocol)
A protocol for exchanging routing information between different networks on the internet.
Bonded Internet
A technology that combines the bandwidth of multiple internet connections to deliver the total amount of bandwidth as a single, virtual connection.
Bring-Your-Own-Bandwidth (BYOB)
This refers to a model where customers use their own internet or bandwidth provider while utilizing a service, such as a cloud-based communication solution, from a separate vendor. This approach allows businesses to control their internet choices independently of other services they use.
Bring-Your-Own-Device (BYOD)
A policy that allows employees to use their personal devices (such as smartphones, laptops, or tablets) to access company resources, applications, and data. This increases flexibility but also introduces security concerns that need to be managed.
Call Centre
A facility or department that handles large volumes of inbound and/or outbound calls, typically for customer service, sales, or technical support. Call centers often use automation tools, such as automatic call distribution (ACD) and interactive voice response (IVR) systems, to manage call traffic efficiently.
Call Forwarding
A telephony feature that allows incoming calls to be redirected to another phone number, such as a mobile phone or a different office line. It ensures that calls are not missed when the intended recipient is unavailable at their primary number.
CDN (Content Delivery Network)
A system of distributed servers that deliver web content to users based on their geographic location.
Cloud PBX
A phone system hosted in the cloud, allowing voice calls to be made over the internet.
Colocation
The practice of housing privately-owned servers and network equipment in a third-party data center.
CPE (Customer Premises Equipment)
Telecommunication hardware located at the customer’s premises, such as media converters, routers or modems.
Data Centre
A facility used to house computer systems and associated components, such as telecommunications and storage systems.
DID (Direct Inward Dialing)
A service that allows businesses to assign direct phone numbers to employees without requiring multiple phone lines.
Digital Fax / E-Fax
Digital faxing, or e-fax, allows users to send and receive faxes via email or the internet instead of a traditional fax machine. This technology converts faxes into digital documents, which are then transmitted electronically to the recipient’s email inbox or cloud storage.
DNS (Domain Name System)
A system that translates domain names into IP addresses, allowing browsers to load websites.
DSL (Digital Subscriber Line)
A technology for transmitting data over traditional copper telephone lines, commonly used for internet access.

FTTC (Fibre to the Cabinet)
A broadband service that uses fiber-optic cables up to a street cabinet, with the final connection to homes via copper cables.
FTTH (Fibre to the Home)
A broadband service that provides a direct fiber-optic connection to the user’s premises.
GPON (Gigabit-capable Passive Optical Network)
A point-to-multipoint (ie, shared) access network that uses fiber optics to provide high-speed internet to homes and businesses.
Hosted PBX

LAN (Local Area Network)
A network of connected devices within a small geographic area, such as a home or office.
Latency
The time delay experienced in a system, often used to describe the delay in data transfer over a network. This is the actual “speed” of your internet connection. Bandwidth, on the other hand, is the amount of data your connection or network can handle at any one time.
LTE (Long-Term Evolution)
A standard for wireless broadband communication for mobile devices and data terminals.
MAC Address
A unique identifier assigned to network interfaces for communications on a network.
MPLS (Multiprotocol Label Switching)

Packet Switching
A method of grouping data into packets for transmission over a digital network.
Power-over-Ethernet (PoE)
A technology that allows network cables to carry electrical power in addition to data. This is useful for devices like IP cameras, wireless access points, and VoIP phones, enabling them to receive power and network connectivity through a single Ethernet cable.

SIP (Session Initiation Protocol)
A protocol used for initiating, maintaining, and terminating real-time communication sessions, such as voice or video calls.
SIP Gateway
A device or software that converts traditional telephony signals into SIP (Session Initiation Protocol) signals, enabling communication between VoIP systems and the public switched telephone network (PSTN).

Twisted Pair Cable
A type of wiring in which two conductors are twisted together to cancel out electromagnetic interference.
UDP (User Datagram Protocol)
A communication protocol used for time-sensitive transmissions, such as video streaming, where error correction is less critical. VoIP also uses UDP.

Unified Communications as a Service (UCaaS)
A cloud-based delivery model for unified communications services, including voice, video, messaging, and collaboration tools. UCaaS allows businesses to subscribe to a suite of communication tools and scale them as needed, without the need for on-premises hardware.
Uptime
The percentage of time a system or service is operational and available for use. 99% uptime equates to, daily, 14 minutes of downtime. A very good uptime percentage is 99.99% (often referred to as “four-nines” uptime).
VLAN (Virtual Local Area Network)
A network configuration that allows a physical network to be divided into multiple virtual networks.
VPN Tunnel
