Configuring an Expand Line-Handler Process That Uses a PVC
If your Expand-over-ATM line-handler process will use a PVC connection, you must
identify the PVC you plan to use. The SCF INFO PVC command displays the
configured name of a PVC.
Example 9-1 shows an example of an SCF INFO PVC command for an ATM line
named $AM1.
The PVC name is displayed in the Name field. As shown in Example 9-1, a PVC named
$AM1.#IP.PVC1 is configured for line $AM1. PVC names take the following form:
$line-name.#atmsap-name.pvc-name.
where $line-name is the name of the ATM line to which the PVC is subordinate,
#atmsap-name is the name of the service access point (SAP) to which service is
being provided, and pvc-name is the name assigned to the PVC. You specify the
pvc-name part of the PVC name when you configure the Expand-over-ATM
line-handler process in Step 3: Create the Line-Handler Process.
Configuring an Expand Line-Handler Process That Uses an SVC
If your Expand-over-ATM line-handler process will use an SVC connection, you must
•
Obtain selector bytes for the ATM lines that will be used by the Expand-over-ATM
line-handler processes at both the local and the remote systems.
•
Identify the ATM address configured for the ATM line that will be used by the
Expand-over-ATM line-handler process at the remote system.
Obtaining Selector Bytes for the Local and Remote ATM
Lines
The selector byte is the last (rightmost) byte of a 20-byte hexadecimal ATM address.
It is used by the ATM subsystem to direct incoming call requests to the correct ATM
subsystem client. Selector bytes must be coordinated among ATM clients using the
same ATM line.
You must obtain unique selector bytes from your network administrator (or whoever
coordinates selector bytes in your ATM network) for the ATM lines that will be used by
