Testing the T1 Setup
Placing Calls over a T1 Line
Testing your application over a live T1 line gives you a
controlled environment and requires no special knowledge of
the protocols. If the application passes a few tests such as
making simultaneous calls or consecutive calls on the same line,
the application will probably work for real calls. However, when
testing the application over a real T1 line, the telephone
company controls the environment so there is little chance to
test error conditions. Before testing an application on a live
T1 line, you should use AccuSpan to eliminate as many error
conditions as possible.
Using a T1 Bulk Call Generator
Using a T1 bulk call generator is a good way to stress-test your
application. Most bulk call generators allow at least four trunks,
or 96 lines, to place calls simultaneously. However, using a
call generator should not replace other tests, particularly tests
over a real line. The bulk call generator usually does not provide
a way of testing error handling since they follow scripts that
you determine and send the correct signals on the line. They
might also handle exceptions and timing issues differently than
your CO.
