800 NI-BRI Module Problems
An 800 NI-BRI module requires running the Provisioning Test, in addition to the
other module tests, under the following circumstances:
■ If the module has data endpoints that use the BRI lines
■ If Voice Call manual testing of the module’s BRI lines indicates problems
The test described in this document supports the NI-1 BRI IOC Package “S”
service configuration. Multiline-Hunt Group/Series Completion testing is
included here.
See Figure 4-6
for a diagram of the entire module testing process. If you have
any questions about the 800 NI-BRI module that this section does not cover,
contact NSAC.
