Cisco ONS 15454 DWDM Installation and Operations Guide, R6.0
September 2005
Chapter 5 Provision Transponder and Muxponder Cards
DLP-G305 Provision the TXP_MR_2.5G and TXPP_MR_2.5G Trunk Port Alarm and TCA Thresholds
Step 10
Enter the appropriate number of occurrences in the Falling Threshold field. In most cases a falling
threshold is set lower than the rising threshold.
A falling threshold is the counterpart to a rising threshold. When the number of occurrences is above the
rising threshold and then drops below a falling threshold, it resets the rising threshold. For example,
when the network problem that caused 1001 collisions in 15 seconds subsides and creates only
799 collisions in 15 seconds, occurrences fall below a falling threshold of 800 collisions. This resets the
rising threshold so that if network collisions again spike over a 1000 per 15-second period, an event again
triggers when the rising threshold is crossed. An event is triggered only the first time a rising threshold
is exceeded (otherwise, a single network problem might cause a rising threshold to be exceeded multiple
times and cause a flood of events).

Step 12
Return to your originating procedure (NTP).
DLP-G305 Provision the TXP_MR_2.5G and TXPP_MR_2.5G Trunk Port Alarm
and TCA Thresholds
Step 1
In node view, double-click the TXP_MR_2.5G or TXPP_MR_2.5G card where you want to change the
trunk port alarm and TCA settings.
Step 2
Click the
Pluggable Port Modules
tab. Under Pluggable Ports, record the Rate that is provisioned.
Step 3
Look up the rate in
and determine whether it is 2R or 3R.
Step 4
Click the
Provisioning > Optics Thresholds
tabs.
Step 5
Click the
15 Min
PM interval radio button and click
Refresh
.
Step 6
Referring to
, provision the trunk port (Port 2) TCA thresholds for RX Power High and RX
Power Low depending on whether the rate is 2R or 3R.
Note
Do not modify the Laser Bias parameters.
Step 7
Click
Apply
.
Purpose
This task changes the TXP_MR_2.5G and TXPP_MR_2.5G trunk port
alarm and TCA thresholds.
