CLE - Customer Located Equipment.
CoS - Class of Service, 802.1Q defined three User priority bits in Tag control Info Field.
DCE - Data Communication Interface.
DSCP - Diff Serve Code Point, IETF defined six bits in the IP ToS field.
DTE - Data Terminating Interface.
EoPDH - Ethernet over PDH. Ethernet encapsulated in HDLC or GFP, transported via one or more PDH lines.
EoPoS - Ethernet transport over PDH over SONET/SDH. Maintaining a PDH framing layer enables re-use of
existing Ethernet-over-SSONET/SDH and PDH-over-SONET/SDH equipment for delivering Ethernet services.
EoS – Ethernet over SONET/SDH.
FCS - Frame Check Sequence.
Frame – A Layer-2 Protocol Data unit. (In general, Layer 2 frames carry Layer 3 packets).
Gapped Clock - Non-continuous clock used to strobe the associated synchronous Data at certain times.
HDLC - High Level Data Link Control.
LAN - Local Area Network. Usually used to refer to a local Ethernet segment.
MAC - Media Access Control. Lowest Digital Layer of Protocol Stack. Performs Framing, Sequencing, and
Addressing.
MII - Media Independent Interface. One type of data bus between the physical layer (PHY) and the MAC.
Packet – A Layer 3 Protocol Data unit.
PDH - Plesiochronous Digital Hierarchy. The existing telephone network’s “last mile.” Primarily T1/E1 lines.
PHY - A device that interfaces an OSI logical layer to a physical media (Cat-5, twisted-pair, etc.). In this
document, interfaces an Ethernet MAC to copper or fiber.
RMII - Reduced Media Independent Interface.
VID- Virtual LAN Identifier.
VCAT - Virtual Concatenation. Used in conjunction with the Link Capacity Adjustment Scheme for transporting
Ethernet over bonded PDH or SDH/SONET tributaries.
WAN - Wide Area Network. Typically T1(DS1), E1, T3(DS3), E3, or xDSL.
