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.
