R0106-HP MSR Router Series Interface Command Reference(V7)

235
Usage guidelines
With payload scrambling enabled, the interface performs payload scrambling when transmitting data,
and payload descrambling when receiving data. Payload scrambling prevents consecutive 0s and 1s in
the payload.
Disabling payload scrambling disables both payload scrambling during data transmission and payload
descrambling during data receiving.
Enable or disable payload scrambling on ATM interfaces of both ends for successful interconnection.
The scramble command does not affect cell headers.
Examples
# Enable payload scrambling on interface ATM 2/4/0.

Usage guidelines
An ADSL interface on a customer premises equipment (CPE) must be activated before it can transmit
services.
Activation refers to the handshake training and information exchange process between the central office
(CO) equipment and the CPE. During this process, the two parties examine the line distance and
conditions against the line configuration template of the CO equipment. The template defines the ADSL
criteria, channel mode, uplink and downlink speeds, and noise tolerance. The parties attempt to reach
an agreement. If the activation succeeds, a connection is set up between the two parties for service
transmission.
