Configuring SDSL Cell Service
126 Avidia System Configuration and Management User Manual
[-scramble (enable|disable)]
Enables or disables cell scrambling. Cell scrambling, used in Avidia, is not an ATM
defined format for SDSL, but is implemented by many vendors. An ATM cell has two
parts: header and payload. Cell scrambling scrambles the payload so that it does not
resemble the header. In the event that an ATM network looses sync, it will attempt to
synchronize on what it sees as the cell header. In some cases, the cell payload can resemble
the cell header, so the network attempts to synchronize on the cell payload rather than the
cell header. Scrambling the cell payload precludes it from looking like a cell header.
Choose to enable or disable cell scrambling based on whether or not the ATM equipment
in the network supports cell scrambling.
Examples
::cell=> set 4.2 3 6 up
::cell=> set 4.2 3 6 up -scramble disable
