Constant Bit Rate (CBR) Configuration (Structured) Screen
Pressing the “c” key from the ACS-ATM Card Main Screen will invoke the Cbr command
and show the CBR Configuration Screen. Because constant-bit-rate (AAL1) traffic does not
consume HDLC channels, it is not subject to the 8 Mbps restriction when using the Variable
Bit Rate options. The total capacity of the PCM-based system bus is 384 DS0s. With AAL1,
the ATM Server Card can adapt and transmit the entire 384 DS0s.
