Release Information
Statement introduced before Junos OS Release 7.4.
Description
Enable or disable HDLC scrambling on an E3, a SONET/SDH, or a T3 interface. This type of scrambling provides better link stability. Both sides of a connection must either use or not use scrambling.
If you commit a T3 interface configuration that has HDLC payload scrambling enabled, the interface must also be configured to be compatible with the channel service unit (CSU) at the remote end of the line.
Disable payload scrambling on an E3 interface if Digital Link compatibility mode is used.
On a channelized OC12 interface, the sonet payload-scrambler statement is ignored. To configure scrambling on the DS3 channels on the interface, you can include the t3-options payload-scrambler statement in the configuration for each DS3 channel.
 | Note: The payload-scrambler statement at the [edit interfaces interface-name e3-options] hierarchy level is not valid for IQE PICs. |
Default
Payload scrambling is disabled on all E3 and T3 interfaces; it is enabled by default on E3/T3 over ATM interfaces and on SONET/SDH interfaces.
