Defining a Service Record
The Configuration Manager allows you to add service records for a specific data
encapsulation type. Depending on the data encapsulation type you choose, the
Configuration Manager also allows you to select a permanent virtual circuit
(PVC) or switched virtual circuit (SVC) connection type for that service record.
Table 1-1 identifies which data encapsulation types you can apply to permanent
and switched virtual circuits.
Adding a Service Record for PVCs
To add a service record for permanent virtual circuits:
1. Click on Service Attributes in the Edit ATM Connector window.
The ATM Service Records List window opens.
2. Click on Add.
The ATM Service Record Parameters window opens.
Caution: You cannot edit the Data Encapsulation Type or Virtual Connection
Type parameters once you assign them to a service record. However, you can
edit the Data Encapsulation Type for individual PVCs.
