system accesses the network integrity buffer and the net path tool recreates
and tests the path. To access the network integrity buffer, enter the
BUFPATH INTEG command at the net path level of the MAP display.
Integrity check traffic simulator feature
This feature sets up large quantities of connections and simulates traffic to
identify call paths that have faults. The net path tool stores data on paths
that have faults in the path fault buffer for testing. To access the path fault
buffer, enter the BUFPATH PATH command at the net path level of the
MAP display.
Bit error rate performance testing feature
This feature tests the complete transmission path through the network.
When this feature detects errors, the bit error rate performance testing
feature displays the tested end-to-end path. The feature also stores the path
data in an output file. To locate the component that causes errors, the net
path tool accesses the data and recreates the path for additional testing.
Network tests available with network path
The tests that you can perform on the network are as follows:
auto
hold
ICTS (ICTS hand over)
loop (network interface)
net (network)
scheduled
Auto
The auto test combines features of the net and loop tests. The auto test does
not require operating company personnel to manually apply these tests to
isolate faults. The system generates two network logs in conjunction with
the auto test: NET104 and NET105. NET104 gives information on cards
and links that have faults. NET105 indicates when a test passes or is
aborted. The duration of the auto test is 1 to 60 min.
Hold
The hold test reserves connections on a defined path for a maximum of 960
min. You can use this test to make a path not available for call processing.
The duration of the hold test is 1 to 960 min.
ICTS
The ICTS hand over test obtains a connection on a specified path and
includes the path in ICTS testing. After the net path test tool detects a card
