Card Provisioning
This chapter provides Cisco ONS 15454 procedures for:
• Changing the default transmission parameters for electrical (EC-1, DS-N) and optical (OC-N) cards,
including provisioning OC-N cards for SDH
• Setting performance monitoring (PM) thresholds, including intermediate path performance
monitoring
• Provisioning the Alarm Interface Controller card
• Converting the DS1-14 and DS3-12 cards from 1:1 to 1:N protection
Note Ethernet card provisioning is described in Chapter 9, “Ethernet Operation.”
Because much of the electrical and optical card provisioning involves PM thresholds, see Chapter 8,
“Performance Monitoring,” for definitions and general information about ONS 15454 performance
monitoring parameters. In addition, refer to the Telcordia GR-1230-CORE, GR-820-CORE, and
GR-253-CORE documents. The default thresholds delivered with ONS 15454 cards are based on
specifications contained in those documents.
Note For information about creating protection groups, see the “Creating Protection Groups” section on
page 3-9. For circuit creation procedures, see Chapter 6, “Circuits and Tunnels.”
7.1 Performance Monitoring Thresholds
ONS 15454 card default thresholds are based on GR-253-CORE and GR-820-CORE. If you change their
settings, the following rules apply:
• The minimum threshold that you can set is 1.
• If you set a threshold to 0, no threshold crossing alert (TCA) is issued.
• You can set thresholds to any DS-N or OC-N maximum. However, CTC does not perform range
checking. Setting a threshold to a value greater than what is logically possible is the same as setting
the threshold to zero. No TCA will be issued.
