eCPE
The initial piece of CPE (Customer Premises Equipment) that is located at the separation point between the demarc extension and the end user’s internal network.
The ‘e’ denotes the exact location of this equipment, at the edge of the end user’s circuit and avoids reference complications when other CPE is used in a demarc extension and/or at a facility.
This equipment is typically a CSU/DSU, Router or Modem.

What is a Demarc Extension?
The transmission path:
originating from the interface of the access provider's side of a telecommunications circuit Demarcation Point within a premise and
ending at the termination point prior to the interface of the edge Customer Premises Equipment.
This may include in-segment equipment, media converters and patch cords as required to complete the circuit's transmission path to the edge CPE.

Part 68 came into effect in 1975, however it was the 1984 Deregulation of the Bell companies that established the demarcation point.
Caused loss of standardization that was maintained by the local access providers prior to deregulations.
Created confusion over responsibility for the demarc extension.

FCC amended the definition of the demarcation point to ensure it would be near the point where the cabling entered the customer’s premises
Enactment of the 12 inch rule which states:The demarcation point may be located within 12 inches of the point at which the wiring enters the customer’s premises.
Still allowed local access providers reasonable and nondiscriminatory standard operating practices for the location of the demarcation point.

FCC clarified the wording of the 12 inch rule by adding the following: "or as near thereto as practicable."
Minimized the location issues for the demarcation point within the premises.
