| Description | This table contains objects used to manage logical or physical
interfaces representing elementary packet streams at the point
where the CDL path defect indications are terminated.
Typically, this is a point where the CDL Ethernet encapsulation
is applied and removed. This can also be a point between a part
of the CDL network that supports packet-by-packet multiplexing,
and a part of the CDL network that does not support
packet-by-packet multiplexing.
Several elementary packet streams (from multiple logical or
physical path terminating interfaces) may be multiplexed into
an aggregate packet stream before being transmitted out of this
network element, towards the rest of the CDL network.

In the figure above, interface 'A' aggregates the elementary
packet streams from interfaces '1' through 'N'. A row in this
table exists for each path terminating interface carrying an
elementary packet stream. In the figure above, these interfaces
are labeled '1' through 'N'.
The relationship between the aggregating interface 'A' and an
interface carrying an elementary packet stream is not specified
in this table. It could be derived from the ifstackTable, or
from a cross connect MIB supported by the platform, or from any
other means suitable to the platform. |
