DEFINITION
Part of the process between a CMTS and the cable modem or
gateway to enable Baseline Privacy.
Automatic medium-dependent interface crossover detects
and corrects cabling errors by automatically reversing the
send and receive pins on any port. It enables the use of
straight-through wiring between the SVG2500 Ethernet port
and any computer, printer, or hub.
DEFINITION
The transmission capacity of a medium in terms of a range of
frequencies. Greater bandwidth indicates the ability to transmit
more data over a given period of time.
An optional feature that encrypts data between the CMTS and
the cable modem or gateway. Protection of service is provided
by ensuring that a cable modem or gateway, uniquely identified
by its MAC address, can only obtain keys for services it is
authorized to access.
The analog signaling rate. For complex modulation modes, the
digital bit rate is encoded in multiple bits per baud. For example,
64 QAM encodes 6 bits per baud, and 16 QAM encodes 4 bits
per baud.
Binary Communication Protocol
The bit error rate is the ratio of the number of erroneous bits or
characters received from some fixed number of bits transmitted.
A numbering system that uses two digits, 0 and 1.
The number of bits (digital 0s and 1s) transmitted per second in
a communications channel. It is usually measured in bits per
second bps.
Baseline Protocol Key Management encrypts data flows
between a cable modem or gateway and the CMTS. The
encryption occurs after the cable modem or gateway
registers to ensure data privacy across the RF network.
