Provisioning Card Mode
Caution High-level data link control (HDLC) framing is not supported.
Note You can use TL-1 to provision the required SONET/SDH point-to-point circuits instead of CTC.
Provisioning Card Mode
The first task in creating an end-to-end RPR-IEEE is to set the CTC card mode to 802.17. For more
information on this task, see the
“Provisioning Card Mode” section on page 2-4 .
Connecting the ML-Series Cards with Point-to-Point STS/STM Circuits
You connect the ML-Series cards in an RPR-IEEE through point-to-point STS/STM circuits. These
circuits use the ONS 15454 SONET/SDH network and are provisioned using CTC in the same general
manner as provisioning ONS 15454 SONET/SDH optical circuits. After putting the ML-Series card in
RPR-IEEE mode and creating the circuits through CTC, further provisioning of the ML-Series card is
done through the Cisco IOS CLI. It is assumed that the SONET/SDH node and its network are already
active.
Guidelines for Connecting the ML-Series Cards with Point-to-Point STS/STM Circuits
These are some general guidelines for configuring the circuits required by RPR-IEEE:
• Verify the CTC card mode for the ML-Series card is set to 802.17. For more information about card
mode, see the
“Provisioning Card Mode” section on page 2-4 .
• You must configure SONET/SDH circuits in an east-to-west configuration, from Port 0 (east) to
Port 1 (west) around the SONET/SDH ring. The ports are labeled East and West in the CTC
card-level view of the ML-Series card being provisioned and in the CTC Circuit Creation Wizard.
The east-to-west provisioning is enforced by the network control program
( NCP). The east-to-west
setup is also required in order for the CTM network management software to recognize the
ML-Series configuration as an RPR-IEEE.
Detailed CTC circuit procedures are available in the NTP-A343, “Create an Automatically Routed OC-N
Circuit,” and the NTP-A344, “Create a Manually Routed OC-N Circuit,” procedures in the “Create
Circuits and VT Tunnels” chapter of the Cisco ONS 15454 Procedure Guide and in the NTP-D323,
“Create an Automatically Routed High-Order Circuit,” and NTP-D 324, “Create a Manually Routed
High-Order Circuit,” procedures in the “Create Circuits and Tunnels” chapter of the Cisco ONS 15454
SDH Procedure Guide.
