NetComm NCT480 manual ATM OAM Test, Portvpi/vci, Virtual circuit for which information is desired

ATM OAM Test

The ATM OAM test generates the ATM F5 loop-back to diagnose the ADSL port interface.

Operation Administration and Maintenance (OA&M) - OA&M is defined for supervision, testing, and performance monitoring. It uses loop-back for maintenance and ITU TS standard CMIP, with organization into 5 hierarchical levels: Virtual Channel (F5 - Between VC endpoints), Virtual Path (F4- between VP endpoints), and Transmission Path (F3- Between elements that perform assembling, disassembling of payload, header, or control), Digital Section (F2 Between section end-points, performs frame synchronization) and Regenerator Section (F1- Between regeneration sections).

Item

Description

Port(vpi/vci)	Loop-back source id assigned to the ATM port. The ATM port will respond to all loop-
	back cells, which carry this OAM id. This parameter specifies the interface, virtual path,
	and virtual circuit for which information is desired.
Result	Use this command to display result of previous OAM loopback command. This specifies
	the result of the loop back test. It may be Result Unavailable, Seg Succeeded, Seg
	Failed, E2e Succeeded, E2e Failed, Test Aborted, or Test In Progress.
