Equipment where the customer or customer-supplied equipment ( CPE ) is any terminal and related equipment located at the customer's premises and connected to the telecommunications circuit operator in demarcation point ("demarc"). The demarc is an established point in a building or complex to separate customer equipment from equipment located in either a distribution infrastructure or a communications service provider's headquarters.
CPE generally refers to devices such as telephones, routers, network switches, residential gateways (RGs), decoders, fixed cellular convergence products, home network adapters and Internet access gateways that allow consumers to access communications service providers and distribute them around their homes over a wide area network local (LAN).
CPE can be an active equipment, as mentioned above or passive equipment such as analog phone adapter or xDSL spliter.
Included is the main telephone system and most of the private branch exchanges. Excluded from CPE are over voltage and payphone protection devices. Other types of materials required for the delivery of telecommunication services, but not defined as equipment, such as manual and cable packages, and cable adapter are referred to as CPE-peripherals.
CPE may refer to the device purchased by the customer, or to those provided by the operator or service provider.

Histori
The two phrases, equipment "customer- equipment " and "customer- provided ", reflects the history of this equipment.
Under the Bell System monopoly in the United States (post Communications Act of 1934), Bell System has a phone, and people can not install their own devices to the network, or even attach anything to the phone. So the phone belongs to the Bell System, located at the customer's premises - hence, the customer equipment - place . In the US Federal Communications Commission (FCC) continued the Second Computer Inquiry, the FCC decided that telecom operators could no longer combine CPE with telecommunication services, relinquish the monopoly power of telecom services from the CPE market, and create a competitive CPE market..
With Bell's gradual outbreak of monopoly, starting with Hush-A-Phone v. United States [1956], which allows some non-Bell owned equipment to be connected to a network (a process called interconnection), the equipment at the customer's premises becomes increasingly owned by customers, not telecommunications companies. Indeed, it was finally able to buy the phone itself - hence, the customer- provided the equipment.
In the Pay-TV industry many operators and service providers offer set-top box subscribers that can be used to receive video services, in return for a monthly fee. Because bidding has evolved to include multiple voice and data services operators are increasingly giving consumers the opportunity to rent or purchase additional devices such as modem access, internet gateways and video extensions that allow them to access multiple services, and distribute them to various Consumer Electronic Devices around home.

Technological evolution
Hybrid device
The growth of multi-service operators, offering triple or quad-play services, requires the development of a hybrid CPE to enable customers to access voice, video and data services. The development of this technology is led by Pay TV operators who are looking for ways to deliver video services through traditional broadcast and broadband IP networks. Spain Telefonica was the first operator to launch a hybrid broadcast and broadband TV service in 2003 by offering Movistar TV DTT/IPTV, while Polish satellite operator 'n' was the first to offer its customers a three-way (or Tri-brid) hybrid broadcast and broadband TV service , which was launched in 2009
Set-back box
The term set-back box is used in the digital TV industry to describe a piece of consumer hardware that allows them to access linear broadcast and internet-based video content, plus various interactive services such as Electronic Program Guides (EPG), Pay Per View (PPV) and video on demand (VOD) as well as internet browsing, and view it on a large screen television set. Unlike standard set-top boxes, which are above or below the TV, the set-back box has a smaller form factor to allow it to be mounted onto the back of the flat panel display panel, hiding it from view.
Home Gateway
Residential gateways are home network devices used to connect devices in the home to the Internet or other WAN. This is an umbrella term, used to cover multi-function home network equipment, which can incorporate DSL modems or cable modems, network switches, consumer class routers, and wireless access points. In the past, such functions were provided by separate devices, but in recent years tech convergence has enabled multiple functions to be combined into one device.
One of the first home gateway devices launched was selected by Telecom Italia to allow operators to offer triple play services in 2002. Along with SIP VoIP handset to make voice calls, it allows subscribers to access voice, video and data services through ADSL symmetric connection 10 MB.
Virtual gateway
The concept of a virtual gateway allows consumers to access video and data services and distribute it around their home using software rather than hardware. The first virtual gateway was introduced in 2010 by Advanced Digital Broadcast at the IBC exhibition in Amsterdam. ADB Virtual Gateway uses software that is in the middleware and is based on open standards, including DLNA home networks and DTCP-IP standards, to ensure that all content, including paid encrypted content such as Pay TV services, is accessible only by a secure CE device.
Broadband
A subscriber unit , or SU is a broadband radio installed in a business or residence location to connect to an access point for sending/receiving high-speed data or wirelessly. The devices commonly referred to as subscriber units include cable modems, access gateways, home network adapters and cell phones.
WAN
The terms "customer's equipment", "customer-provided equipment" or "CPE" may also refer to any device that terminates the WAN chain, such as ISDN, E-carrier/T-carrier, DSL, or Ethernet metrics. This includes customer-owned hardware on customer sites: routers, firewalls, network switches, PBXs, VoIP gateways, sometimes CSU/DSU and modems.
Application area
- Connected home
- Pay TV
- Over-the-top video service
- Broadband
- Voice over IP
- Fixed-mobile convergence [FMC]
Other uses
- Mobile operators can sometimes refer internally to cell phones purchased by customers without subsidies or from third parties as "customer-provided equipment."
- It is also important that fully qualified domain names and PTR records on DSLs and cable channels connected to residence often contain 'cpe'.
