ATM ATMSAPs

The ATMSAP object represents a service access point (SAP) for native-mode clients.

Native-mode clients, such as TCP/IP, register to the service-access points. ATMSAP

objects are created by the subsystem after the ADAPTER has been started. Currently,

the only ATMSAP object is #IP.

ATMSAP names have the form $line-name.#ATMSAP-name, where $line-name is

the name of the ATM logical line. #ATMSAP-name is the name of the ATMSAP.

The ATMSAP-name consists of up to seven alphanumeric characters with a leading

alphabetic character; for example, $AM1.#IP. The names are predefined by the

adapter.

The ATMSAP object is subordinate to the LINE object.

ATM LINE

The LINE object represents the ATM line or link connected to the ATM adapter. The

LINE object is created by the subsystem when an ADAPTER object is added to the

subsystem. The LINE receives its name from the ADAPTER object.

The LINE object is subordinate to the ADAPTER object.

ATM NULL

The null object means that no object type was specified.

ATM PVC

The PVC object represents a permanent virtual circuit. PVCs are created by using the

SCF ADD PVC command.

PVC names have the form $line-name.#atmsap-name.pvc-name.

$line-name is the name of the ATM line to whom the PVC is subordinate.

#atmsap-name is the name of the SAP to which service is being provided.

pvc-name is the name assigned by the adapter to identify the circuit. The pvc-name

consists of up to eight alphanumeric characters with a leading alphabetic character; for

example, $AM1.#IP.PVC0.

ATM SUBSYS

The SUBSYS object represents the ASM. The ASM runs as a process pair and is

added to the system that uses the $ZZKRN subsystem.

Note. Although the PVC object name includes the name of the ATMSAP, the PVC object is not

subordinate to the ATMSAP. The naming format shows only that there is a fixed relationship

between a PVC and an ATMSAP.
