EPP

Extensible Provisioning Protocol

ePRTC

Enhanced Primary Reference Time Clock

equal access costs

Include only initial incremental presubscription costs and initial incremental expenditures for hardware and software related directly to the provision of equal access which would not be required to upgrade the switching capabilities of the office involved absent the provisions of equal access. [47 CFR Pt.36-A]

equal gain combiner

A diversity combiner in which the signals on each channel are added.
Note: The channel gains can be made to remain always and everywhere equal so that the resultant signal remains approximately constant.

Equal Level Echo Path Loss

The term "Equal Level Echo Path Loss" (ELEPL) denotes the measure of Echo Path Loss (EPL) at a 4-wire interface which is corrected by the difference between the send and receive Transmission Level Point (TLP). [ELEPL = EPL - TLP (send) + TLP (receive)].

equal-length code

A telegraph or a data code in which (a) all the words or code groups are composed of the same number of unit elements, (b) each element has the same duration or spatial length, (c) each word or code group has the same duration or spatial length, and (d) usually each word or code group has the same number of… (Read More →)

equal-level patch bay

An analog patching facility at which all nominal input and output voice frequency levels are uniform.
Note: The use of an equal-level patch bay permits patching without making transmission level adjustments.

equalization

The maintenance of system transfer function characteristics within specified limits by modifying circuit parameters.
Note: Equalization includes modification of circuit parameters, such as resistance, inductance, or capacitance.

equatorial orbit

For a satellite orbiting the Earth, an orbit in the equatorial plane.
Note: An equatorial orbit has an inclination angle of 0°.
