10Base-T
The IEEE 802.3 standard for Ethernet. 10Base-T uses standard telephone wire (twisted pair)
and standard RJ-45 connectors.
1B call
A voice or video call that uses only one B (bearer) channel of an ISDN line. The bandwidth
used is 64 Kbps or 56 Kbps (restricted networks). The VIU-323 does not support 1B calls.
2B call
A video call that uses 2B (bearer) channels of an ISDN line. The bandwidth used is 2x64
Kbps or 2x56 Kbps (restricted networks).
B channel
Bearer Channel. In ISDN communications, a B channel transmits data or voice at 64 Kbps
or 56 Kbps (restricted networks).
bandwidth
The data transmission capacity of a channel measured in bits per second (bps, e.g., Kbps
stands for kilobits per second, Mbps for megabits per second). The bandwidth of 10Base-T
Ethernet is 10Mbps.
channel bonding
Increasing the bandwidth of a call by aggregating two or more channels of an ISDN line.
CIF
Common Interface Format; a high resolution video format that provides 288 lines times 352
pixels at up to 30 frames per second. Also known as FCIF (Full CIF).
console port
The serial port on the front panel of the VIU-323 that connects to a terminal or to a modem.
This port is used for local monitoring, diagnostics and remote configuration.
