Customer provided equipment (CPE)

In telecommunications, a customer-premises equipment or customer-provided equipment (CPE) is any terminal and associated equipment located at a subscriber’s premises and connected with a carrier’s telecommunication circuit at the demarcation point (“demarc”). The demarc is a point established in a building or complex to separate customer equipment from the equipment located in either the distribution infrastructure or central office of the communications service provider.

CPE generally refers to devices such as telephones, routers, network switches, residential gateways (RG), set-top boxes, fixed mobile convergence products, home networking adapters and Internet access gateways that enable consumers to access communications service providers’ services and distribute them around their house via a local area network (LAN).

A CPE can be an active equipment, as the ones mentioned above, or a passive equipment, such as analogue-telephone-adapters or xDSL-splitters.

System Requirements for CPEs

Environment: bare metal, ESX, Xen.
Throughput and required CPU is listed in the performance ratings document.
If tunnel encryption is enabled, AES acceleration instruction set is recommended for faster speeds.

RAM: 256 MB minimum, 1 GB recommended.

Disk: minimum 4 GB. For highest reliability, use hard disks, solid state disks, or flash storage with good wear-leveling algorithms. Flash storage without good wear-leveling algorithms tend to fail sooner than other types of storage.
