Glossary
broadband
broadband A technology that provides an extremely wide and fast bandwidth so that
many people can simultaneously use the service. It is generally
associated with multiple types of transmissions on the same connection
such as voice, data, video and digital or analog information.
C-bit Coding
Violation
(CCV)
For C-bit Parity and SYNTRAN DS3 applications, this is the count of
coding violations reported via the C-bits. For C-bit Parity, it is a count of
CP-bit parity errors occurring in the accumulation interval. For
SYNTRAN, it is a count of CRC-9 errors occurring in the accumulation
interval.
C-bit Errored
Seconds (CES)
An CES is a second with one or more CCVs OR one or more Out of
Frame defects OR a detected incoming AIS. This count is only for the
SYNTRAN and C-bit Parity DS3 applications. This gauge is not
incremented when UASs are counted.
C-bit Severely
Errored
Seconds (CSES)
A CSES is a second with 44 or more CCVs OR one or more Out of Frame
defects OR a detected incoming AIS. This count is only for the
SYNTRAN and C-bit Parity DS3 applications. This gauge is not
incremented when UAS are counted.
CDPD Cellular Digital Packet Data. A radio technology that supports the
transmission of packet data to speeds of up to 19.2 Kbps over the existing
analog AMPS (Advanced Mobile Phone Service) cellular network, with
appropriate CDPD upgrades.
Central Office
(CO)
Where telephone companies terminate customer lines and locate
switching equipment to interconnect those lines with other networks.
Challenge
Handshake
Authorization
Protocol
(CHAP)
A strong authentication method used with PPP for user login. A type of
authentication in which the authentication agent (typically a network
server) sends the client program a key to be used to encrypt the username
and password. This enables the username and password to be transmitted
in an encrypted form to protect them against eavesdroppers. When using
CHAP, the username/password is sent encrypted over the connection,
preventing sniffing. See also PAP.
