List of terms

pulse code modulation (PCM)

A standardized method of producing digital speech. Defined in ITU-T G.711.

PVC

1See permanent virtual channel (PVC) (page 101).

2See permanent virtual circuit (PVC) (page 101).

PVG

See packet voice gateway (PVG) (page 96).

PVID

See port-VLAN identifier (PVID) (page 104).

PVP

See permanent virtual path (PVP) (page 101).

Q interface signaling (QSIG)

An internationally defined inter-PBX signaling standard. Defined in European Telecommunications Standards Institute (ETSI) specifications.

QC

See queue controller (QC) (page 110).

QOS, QoS, Qos

See quality of service (QOS, QoS, Qos) (page 109).

QSIG

See Q interface signaling (QSIG) (page 109).

Q-tag

An abbreviated name for the IEEE 802.1Q VLAN tag header that consists of the TPID and TCI sub-headers. This header identifies the user priority and LAN identification for an Ethernet packet.

QRD

See queue relay device (QRD) (page 110).

quality of service (QOS, QoS, Qos)

A series of service classes that reflect the traffic importance and urgency over a connection.

For ATM networks and services, QOS classes are defined by the ATM Forum for UNI 3.0/3.1 and UNI 4.0. Nortel Multiservice Switch system also defines a set of corresponding ATM QOS classes (UBR, CBR, VBR, CO, CNLS).
