Agilent Technologies, Inc. E6270A OAM Protocol Tester
The large-scale deployment of ATM networks and services presents complex network management challenges for both network equipment manufacturers and service providers. Customers who pay for the delivery of multimedia services and mission-critical data over ATM networks demand that they receive the levels of performance, quality, and availability defined in the SLA (Service Level Agreement). The ATM Operations, Administration, and Maintenance (OAM) protocol offers standardized, in-service tools for network monitoring. It enables ATM network elements to gather status information about individual ATM connections. OAM capabilities include:
Reporting of fault conditions and fault location
Rapid detection of loss of ATM connection continuity
Diagnostic loopback testing
Real-time measurement of connection quality (block-level QoS parameters)
Remote activation/deactivation of OAM diagnostic functions
The HP E6270A OAM Protocol Tester (OPT) is part of the modular HP Broadband Series Test System (BSTS). It is a dedicated module for in-depth verification of OAM implementations. The OPT provides extensive simulation, monitoring, and emulation capabilities over multiple channels. It can be used for the verification of all aspects of OAM:
Fault-detection (AIS, RDI, CC)
Fault-localization (loopback)
Performance management (QoS measurement and reporting)
Activation/deactivation (of fault management and performance management functions)
