supported by the particular test to be executed. Particularly, the asymmetric test is
available in RFC 2544 and eSAM tests only (See section 7.1, See section 7.2).
Finally, the remote bidirectional test is similar to the asymmetric Upstream and
Downstream methods but in the bidirectional test traffic flows between the controller
and the responder. The remote bidirectional test applies only to RFC 6349 tests.
Table 7.14: Test Mode Configuration
Setting Description
Remote managed
Enables or disables the responder operation in the unit. If this
mode is enabled, most of the test unit functionality is con-
trolled by a remote Albedo unit (See section 7.5).
Test method Configures the way the currently configured test is to be exe-
cuted. It is one of the following:
• One-way (A>B): Port A is configured for traffic generation.
Port B becomes an analyser. This mode is suitable for
measurements in open paths in the network and it is appli-
cable to RFC 2544, eSAM and Y.1564 tests.
• Two-way (A>A): Port A is configured both for traffic gener-
ation and traffic analysis. This mode is suitable for meas-
urements in closed paths in the network and it applies to
RFC 2544 and eSAM tests.
• Upstream: Configures the unit as a controller in an asym-
metric test. The controller becomes a traffic generator and
the responder an analyser. This test method is therefore
suitable for the analysis of the path that goes from the con-
troller to the responder. This test method is available only if
one of the RFC 2544 or eSAM performance tests has
been previously enabled.
• Downstream: Configures the unit as a controller in an
asymmetric test. The controller becomes a traffic analyser
and the responder generates test traffic.This test method
is therefore suitable for the analysis of the path that goes
from the responder to the controller. This test method is
available only if one of the RFC 2544 or eSAM perfor-
mance tests has been previously enabled.
• Bidirectional. Configures the unit as a controller in
RFC 6349 dual-ended tests. The unit generates com-
mands to control a remote unit running in responder mode
and gets test results and status from the far end.
