B
bandwidth | 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. | |
Baseline | An optional feature that encrypts data between the CMTS and the cable modem or gateway. | |
Privacy | 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. | |
baud | 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. | |
BCP | Binary Communication Protocol |
|
BER | The bit error rate is the ratio of the number of erroneous bits or characters received from some fixed | |
| number of bits transmitted. |
|
binary | A numbering system that uses two digits, 0 and 1. |
|
bit rate | The number of bits (digital 0s and 1s) transmitted per second in a communications channel. It is | |
| usually measured in bits per second bps. |
|
BPKM | 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. |
|
bps | bits per second |
|
bridge | An OSI layer 2 networking device that connects two LANs using similar protocols. It filters frames | |
| based on the MAC address to reduce the amount of traffic. A bridge can be placed between two | |
| groups of hosts that communicate a lot together, but not so much with the hosts in the other group. | |
| The bridge examines the destination of each packet to determine whether to transmit it to the other | |
| side. See also switch. |
|
broadband | High bandwidth network technology that multiplexes multiple, independent carriers to carry voice, | |
| video, data, and other interactive services over a single cable. A communications medium that can | |
| transmit a relatively large amount of data in a given time period. A frequently used synonym for cable | |
| TV that can describe any technology capable of delivering multiple channels and services. | |
broadcast | Simultaneous transmission to multiple network devices; a protocol mechanism supporting group and | |
| universal addressing. See also multicast and unicast. |
