ATM Interfaces and Ports
This section describes the minimum configuration required to use IP over ATM (IPoA) through an Optical ATM line
card (OLC/OLC2). The procedures describe how to:
card (OLC/OLC2). The procedures describe how to:
Step 1
Set the framing method for a specific OLC-type line card and make the card “active” by using the procedure defined in
Step 2
Step 3
Enable the ATM port, create the IPoA (PVC) interface for the ATM port, and enable the PVC by applying the example
configuration in
configuration in
Steps 2 and 3 together configure the data plane.
Step 4
Step 4 configures the control plane through an SS7/IPoA (PVC) interface.
Important:
Do not attempt to bind the link at this time. Complete the rest of the procedure (steps 5, 6, and 7)
and return to bind the link to the port. The SS7 link can only be bound to the ATM port after the configuration for the
SS7 routing domain has been completed as described in the 3G SGSN Configuration section of the SGSN
Administration Guide.

Administration Guide.
Step 5
Configure the appropriate timing source (BITS from the SPIO or line-timing from an attached remote) to ensure
transmit synchronization by applying the example configuration in the Configuring Transmit Timing Source section of
System Settings.

Step 7
Save the configuration as described in the Verifying and Saving Your Configuration chapter.
Enabling the OLC (ATM) Line Card
Use the following example to select an OLC and set the framing type:
