This chapter describes the tasks related to node configuration in Cisco Optical Site Manager.
If Cisco Optical Site Manager is used to manage an XR device, any configuration changes made to the device using XR (CLI or
NETCONF) will trigger a resynchronization of the device in Cisco Optical Site Manager. This means that Cisco Optical Site
Manager will temporarily be out of sync with the device while it updates itself with the changes. Any alarms during this period
will be reported on Cisco Optical Site Manager after the synchronization process is complete.
Note
Removing any line card from the XR device will cause the configuration of the card to revert to the preconfigure state. This
will result in the same behavior described above.
Figure 1. Configure the Node
Import the Cisco Optical Network Planner Configuration File
If you have a configuration file NETCONF file (.xml) exported from Cisco Optical Network Planner, you can import it to Cisco
Optical Site Manager. The file includes parameters for the node, shelf, card type, port (including the wavelength of the card),
pluggable port module (PPM), OTN, and FEC parameters.
Only the values present in XML format appear in the configuration file parameters. If the values are not in XML format, a
column appears blank. The XML file values are independently reported and do not affect any configuration changes that you
apply.

Automatic Power Control
The Automatic Power Control (APC) feature performs the following functions:
Maintains constant per-channel power increases optical network resilience, even when changes to the number of channels occur.
Compensates for the degradation of optical networks caused by aging effects.
Simplifies installation and upgrades of DWDM optical networks by automatically calculating amplifier setpoints.
The amplifier software uses a control gain loop to keep channel power constant regardless of the number of channels. It monitors
input power changes and adjusts output power proportionately. The shelf controller software emulates the control output power
loop to compensate for fiber degradation.
For proper functioning, the control card needs to know the channel distribution via a signaling protocol, and the expected
per-channel power which you can set. It compares actual amplifier output power with expected power and adjusts setpoints if
needed.
APC at the Shelf Controller Layer
Amplifiers are managed through software to monitor
changes in the input power. Changes in the network characteristics have an impact on
the amplifier input power. Changes in the input power are compensated for by only
modifying the original calculated gain, because input power changes imply changes in
the span loss. As a consequence, the gain to span loss established at the amplifier
start-up is no longer satisfied, as shown in the following figure.
Figure 2. Using Amplifier Gain
Adjustment to Compensate for System Degradation
In the preceding figure, Node 1 and Node 2 are equipped with booster amplifiers and
preamplifiers. The input power received at the preamplifier on Node 2 (Pin2) depends
on the total power launched by the booster amplifier on Node1, Pout1(n) (where n is
the number of channels), and the effect of the span attenuation (L) between the two
nodes. Span loss changes due to aging fiber and components or changes in operating
conditions. The power into Node 2 is given by the following formula:
Pin2 = LPout1(n)
The phase gain of the preamplifier on Node 2
(GPre-2) is set during provisioning to compensate for the span loss so that the Node
2 preamplifier output power (Pout-Pre-2) is equal to the original transmitted power,
as represented in the following formula:
Pout-Pre-2 = L x GPre-2 x Pout1(n)
In cases of system degradation, the power received at Node 2 decreases due to the change of span insertion loss (from L to
L'). As a consequence of the preamplifier gain control working mode, the Node 2 preamplifier output power (Pout-Pre-2) also
decreases. The goal of APC at the shelf controller layer is simply to detect if an amplifier output change is needed because
of changes in the number of channels or to other factors. If factors other than the "changes in the number of channels" factor
occur, APC provisions a new gain at the Node 2 preamplifier (GPre-2') to compensate for the new span loss, as shown in the
formula:
Generalizing on the preceding relationship, APC is able to compensate for system degradation by adjusting working amplifier
gain or variable optical attenuation (VOA) and to eliminate the difference between the power value read by the photodiodes
and the expected power value. The expected power values are calculated using:
Provisioned per channel power value
Channel distribution (the number of express, add, and drop channels in the node)
ASE estimation
Channel distribution is determined by the sum of the provisioned and failed channels. Information about provisioned wavelengths
is sent to APC on the applicable nodes during the circuit creation. Information about failed channels is collected through
a signaling protocol that monitors alarms on ports in the applicable nodes and distributes that information to all the other
nodes in the network.
ASE calculations purify the noise from the power
level that is reported from the photodiode. Each amplifier can compensate for its
own noise, but cascaded amplifiers cannot compensate for ASE generated by preceding
nodes. The ASE effect increases when the number of channels decreases; therefore, a
correction factor must be calculated in each amplifier of the ring to compensate for
ASE build-up.
APC is a network-level feature that is distributed among different nodes. An APC domain is a set of nodes that are regulated
by the same instance of APC at the network level. An APC domain optically identifies a network portion that can be independently
regulated. Every domain is terminated by two node sides residing on a terminal node, ROADM node, hub node, line termination
meshed node, or an XC termination meshed node. An optical network can be divided into several different domains, with the
following characteristics:
Every domain is terminated by two node sides. The node sides terminating domains are:
Terminal node (any type)
ROADM node
Hub node
Cross-connect (XC) termination mesh node
Line termination mesh node
APC domains are shown in the GUI.
Inside a domain, the APC algorithm designates a primary node that is responsible for starting APC hourly or every time a new
circuit is provisioned or removed. Every time the primary node signals APC to start, gain and VOA setpoints are evaluated
on all nodes in the network. If corrections are needed in different nodes, they are always performed sequentially following
the optical paths starting from the primary node.
APC corrects the power level only if the variation exceeds the hysteresis thresholds of +/– 0.5 dB. Any power level fluctuation
within the threshold range is skipped because it is considered negligible. Because APC is designed to follow slow time events,
it skips corrections greater than 3 dB. This is the typical total aging margin that is provisioned during the network design
phase. After you provision the first channel or the amplifiers are turned up for the first time, APC does not apply the 3-dB
rule. In this case, APC corrects all the power differences to turn up the node.
To avoid large power fluctuations, APC adjusts power levels incrementally. The maximum power correction is +/– 0.5 dB. This
is applied to each iteration until the optimal power level is reached. For example, a gain deviation of 2 dB is corrected
in four steps. Each of the four steps requires a complete APC check on every node in the APC domain. APC can correct up to
a maximum of 3 dB on an hourly basis. If degradation occurs over a longer time period, APC compensates for it by using all
margins that you provision during installation.
APC can be manually disabled. In addition, APC automatically disables itself when:
A Hardware Fail (HF) alarm is raised by any
card in any of the domain nodes.
A Mismatch Equipment Alarm (MEA) is raised by any card in any of the domain nodes.
An Improper Removal (IMPROPRMVL) alarm is raised by any card in any of the domain nodes.
Gain Degrade (GAIN-HDEG), Power Degrade (OPWR-HDEG), and Power Fail (PWR-FAIL) alarms are raised by the output port of any
amplifier card in any of the domain nodes.
A VOA degrade or fail alarm is raised by any of the cards in any of the domain nodes.
The signaling protocol detects that one of the APC instances in any of the domain nodes is no longer reachable.
APC raises the following minor, non-service-affecting alarms:
APC Out of Range—APC cannot assign a new setpoint for a parameter that is allocated to a port because the new setpoint exceeds
the parameter range.
APC Correction Skipped—APC skipped a correction to one parameter allocated to a port because the difference between the expected
and current values exceeds the +/– 3-dB security range.
APC at the Amplifier Card Level
In constant gain mode, the amplifier power out control
loop performs the following input and output power calculations, where G represents
the gain and t represents time.
Pout (t) = G * Pin (t) (mW)
Pout (t) = G + Pin (t) (dB)
In a power-equalized optical system, the input power scales with the number of channels, and the amplifier software adjusts
for power fluctuations caused by changes in the incoming signal's channel count.
The amplifier software detects input power changes at two instances, t1 and t2, as traffic fluctuations occur. In the formula,
'm' and 'n' denote distinct channel numbers, and Pin/ch signifies the input power per channel.
Pin (t1)= nPin/ch
Pin (t2) = mPin/ch
The output power is quickly adjusted in response to input power changes, maintaining constant power for each channel, even
during upgrades or fiber cuts, with a reaction time in milliseconds.
The power and mode for each channel are determined by Automatic Node Setup (ANS) on a per-degree basis during provisioning.
Forcing Power Correction
A wrong use of maintenance procedures can lead the system to raise the APC Correction Skipped alarm. The APC Correction Skipped
alarm strongly limits network management (for example, a new circuit cannot be converted into In-Service (IS) state).
The Force Power Correction button in the APC section helps the user to restore normal conditions by clearing the APC Correction Skipped alarm. The use of the Force Power Correction button must be supervised by Cisco TAC to prevent any traffic loss.

Span Loss Measurement
Span loss measurements (in dB) check the span loss and are useful whenever changes to the network
occur.
The span loss operational parameters are:
Measured By—Displays whether the span loss is measured by the channel or Optical Service Channel (OSC). If a channel is not configured,
the span loss is measured by the OSC. An EDFA measures the span loss based on circuits.
Measured Span Loss—Displays the measured span loss.
Measured Span Loss Accuracy—Displays the accuracy of the
span loss measurement. For example, if the measured span loss is 20 dB and the
displayed accuracy value is 2.5, the actual span loss could either be 19 or 21
dB.
Measured Time—Displays the time and date when the last span loss measured value is changed.
If there is a new network with Cisco Optical Site Manager, the operational parameters list of span loss has two rows.
The first row displays the OSC-measured span loss details. After the channel is
configured, the second row is added, which displays the channel-measured span loss
details. After the channel is configured, only the channel-measured span loss details
are updated.
