Reference Information
Overview of This Appendix
This appendix contains reference information that is helpful while configur-
ing your PSAX system. The following types of information are provided:
•
“Avoiding Common Errors When Configuring Interfaces”
•
“Optimizing SVC Call Performance”
•
“Connection Type by Interface Type”
•
“Interface Type by I/O Module Type”
•
“Module Alarm Status Descriptions”
•
“ATM Service Categories in the PSAX System”
•
“ATM TS, UPC, and VI Configuration Capabilities”
Avoiding Common Errors When Configuring Interfaces
An error may occur when you apply an interface to a channel. If an error
condition occurs, the PSAX system sends an SNMP trap that is usually dis-
played in the console Trap Log Display window (accessible from the Console
Interface Main Menu window). The list below includes the most common
interface errors that cause the PSAX system to display a message. (See the
PacketStar
®
PSAX Simple Network Management Protocol (SNMP) Trap Reference
Guide
for more information about the SNMP traps related to interface errors).
•
Entering field values that are outside of the configurable range of values
•
Attempting to configure an interface for a port or channel that has already
been configured
•
Attempting to configure an interface that is already in service (must be out
of service to be configured or change field values)
•
Entering field values that are not recognized by the PSAX system software
Optimizing SVC Call Performance
The information in this section provides guidance on optimizing call perfor-
mance when configuring SVCs on the PNNI interface. The service-specific
connection-oriented protocol (SSCOP) parameter is set on these interface
configuration windows: ATM IISP network or IISP user, ATM UNI 3.0 or
UNI 3.1, or ATM PNNI 1.0.
Note:
These settings are suggested for connecting to a PSAX system from
a remote site only. The PSAX system configures these settings
internally in its own ATM switch.
