9.8 Non-DWDM (TDM) Networks
Non-DWDM (TDM) Networks take synchronous and asynchronous signals and multiplexes them to a
single higher bit rate for transmission at a single wavelength over fiber. When the node is configured as
a Non-DWDM Network, the supported MSTP cards — amplifiers, transponders, and muxponders, are
used in the standalone mode. MSTP applications like Circuit Provisioning, NLAC and APC are not
supported in amplified TDM networks. For more information on how to configure a node as a
Non-DWDM network, see the “NTP-G320 Configure the Node as a Non-DWDM Network” section in
“Turn Up a Node” chapter in the Cisco ONS 15454 DWDM Procedure Guide.
When the node is configured as a Not-DWDM network, all the amplifiers are configured by default with
the following values:
• Working mode = Control Gain
• Channel Power Ref. = +1dBm.
Booster(LINE) amplifiers enable optical safety when used in Non-DWDM. ALS configuration is set to
“Auto Restart” by default. A manual restart request is therefore needed to turn up the bidirectional link,
in addition with an appropriated cabling (bi-directional) of LINE TX/RX ports.
In NOT-DWDM mode, you must configure significant optical parameters and thresholds before
launching the ANS application. For information on how to configure the amplifier, see the “DLP-G693
Configure the Amplifier” section in “Turn Up a Node” chapter in the Cisco ONS 15454 DWDM
Procedure Guide. For information on how to configure the PSM behavior, see the “DLP-G694 Configure
the PSM” section in “Turn Up a Node” chapter in the Cisco ONS 15454 DWDM Procedure Guide.
When the ANS application is launched, amplifier ports move into IS state and Gain Setpoint is
automatically calculated by the card, after initial APR cycle. Gain Setpoint must be equal to MAX [Min
Gain Setpoint of the card ; (Power Ref-Pinput)]; where Pinput is the optical power value at the ingress
port (COM-RX) of the amplification stage.
