HAPTER 10: PACKET OVER SONET ADMINISTRATION
Line Configures the POS interface to loop-back data to the
originating device. While configured in this mode, the
interface loops back and retransmits incoming data without
actually receiving it.
Internal Configures the POS interface to loop-back data to itself.
While configured in this mode, the interface loops-back
outgoing data to the receiver without actually transmitting it.

Defect
Indication
Configure enhanced or normal path remote defect indication
on this interface Currently not supported.
Clock Source SONET is a synchronous transport technology. When
configuring point-to-point links, one side of the link should
be configured to utilize a line clock source, the other should
utilize an internal clock source.
Timing for this synchronous transmission of data is derived
from one of these clock sources.
Line Also referred to as loop timing, this timing option configures
the interface to use the recovered receive clock to provide
transmit clocking. This is the default clock source.
Internal Configures the interface to generate the transmit clock
internally.
Signal Type Configures the type of signal (framing) this POS interface
transmits. Currently, the system supports only SONET STS-3c
and STS-12c framing.
Packet
Scrambling
Enables scrambling of SONET Synchronous Payload Envelopes
(SPEs) on this interface. Note that both end-points of the
transmission must use the same scrambling. Scrambling is
disabled by default. Read-only.
Line Coding This variable identifies whether a SONET or an SDH signal is
used across this interface. Read-only.
Line Type This variable describes the line coding for this interface. The
B3ZS and CMI are used for electrical SONET/SDH signals
(STS-1 and STS-3). The Non-Return to Zero (NRZ) and the
Return to Zero are used for optical SONET/SDH signals.
Read-only.
