description
"This module describes a terminal optics device model for
managing the terminal systems (client and line side) in a
DWDM transport network.
Elements of the model:
physical port: corresponds to a physical, pluggable client
port on the terminal device. Examples includes 10G, 40G, 100G
(e.g., 10x10G, 4x25G or 1x100G) and 400G/1T in the future.
Physical client ports will have associated operational state or
PMs.
physical channel: a physical lane or channel in the
physical client port. Each physical client port has 1 or more
channels. An example is 100GBASE-LR4 client physical port having
4x25G channels. Channels have their own optical PMs and can be
monitored independently within a client physical port (e.g.,
channel power). Physical client channels are defined in the
model as part of a physical client port, and are modeled
primarily for reading their PMs.
logical channel: a logical grouping of logical grooming elements
that may be assigned to subsequent grooming stages for
multiplexing / de-multiplexing, or to an optical channel for
line side transmission. The logical channels can represent, for
example, an ODU/OTU logical packing of the client
data onto the line side. Tributaries are similarly logical
groupings of demand that can be represented in this structure and
assigned to an optical channel. Note that different types of
logical channels may be present, each with their corresponding
PMs.
optical channel: corresponds to an optical carrier and is
assigned a wavelength/frequency. Optical channels have PMs
such as power, BER, and operational mode.
Directionality:
To maintain simplicity in the model, the configuration is
described from client-to-line direction. The assumption is that
equivalent reverse configuration is implicit, resulting in
the same line-to-client configuration.
Physical layout:
The model does not assume a particular physical layout of client
and line ports on the terminal device (e.g., such as number of
ports per linecard, separate linecards for client and line ports,
etc.).";
