Performance monitoring
Available TP
Looking at the table below, the termination points that can be monitored unidirectional
and bi-directionally are:
• VC-11, VC-12, VC-3,VC-4
The following termination points support only uni-directional performance monitoring:
• P12 (ISDN), MS–1 and MS-4
Prerequisite to monitor
In order to monitor the performance of the network at a given termination point, two
prerequisites must be met:
1. The performance parameter(s) counter(s) must be enabled;
2. The port mode must be set to monitored. For more information on the specific
procedure to follow, please refer to
specifically to
related to port modes, please refer to
Bi-directional monitoring
The 1643 AM or 1643 AMS has the capability, not only to handle unidirectional, but
also bidirectional performance monitoring. By setting two termination points at both
ends of the path, end-to-end monitoring can be done.
Maximum number of TPs
It is possible to simultaneously monitor a number of termination points. The maximum
is limited by the number of counters that can be simultaneously enabled. Bidirectional
monitoring processes may count as two monitoring points.
The maximum number of monitoring points that can be provisioned on a network
element vary according to the type of system controller installed on the 1643 AM or
1643 AMS. Please consult the technical specifications of the network element in the
AGP manual.
Forward and backward monitoring
On connection termination points (CTPs) the signal is non-intrusively monitored. This
kind of monitoring does not terminate the signal but only reads its REI value.
