NPE Crosstalk Test (#6)<br />

Description / Recommendation<br />

NPE Crosstalk Test (#6)<br />

14 FAIL DC-powered cabinet: The PN’s Maintenance circuit pack is<br />

incorrectly reporting a problem with power. Replace the suspect circuit<br />

pack <strong>and</strong> run the <strong>test</strong> again.<br />

AC-powered cabinet: Error <strong>codes</strong> 2, 4, <strong>and</strong> 8 have occurred. Refer to<br />

these <strong>descriptions</strong>.<br />

This could also indicate that the detection logic on the PN’s MAINT<br />

(Maintenance) circuit pack is defective. Such an <strong>error</strong> will not be<br />

detected by the respective maintenance. If many environment <strong>test</strong>s are<br />

failing, replace the suspect circuit pack, depending on the system<br />

configuration.<br />

Any FAIL The PN’s Maintenance circuit pack is incorrectly reporting a problem<br />

with power. Replace the suspect circuit pack <strong>and</strong> run the <strong>test</strong> again.<br />

PASS No power problems exist.<br />

For the majority of maintenance objects, this <strong>test</strong> is known as the NPE Crosstalk Test (#6). One<br />

or more Network Processing Elements (NPEs) reside on each circuit pack with a TDM Bus<br />

interface. The NPE controls port connectivity <strong>and</strong> gain, <strong>and</strong> provides conference functions on a<br />

per-port basis. This <strong>test</strong> verifies that the port’s NPE chel talks on the selected time slot <strong>and</strong><br />

never crosses over to time slots reserved for other connections. If the NPE is not working<br />

correctly, one-way <strong>and</strong> noisy connections may be observed. This <strong>test</strong> takes about 20 to 30<br />

seconds to complete.<br />

For MMI-BD, this <strong>test</strong> is known as the TSI Crosstalk Test (#6). The Time Slot Interchanger (TSI)<br />

chip controls connectivity to the TDM bus. The TSI Crosstalk <strong>test</strong> verifies that this TSI talks on<br />

the selected TDM bus time slot <strong>and</strong> never crosses over to time slots reserved for other<br />

connections. If the TSI is not working correctly, one-way <strong>and</strong> noisy connections may occur. If the<br />

<strong>test</strong> passes, the TSI can communicate over the TDM bus. This <strong>test</strong> takes approximately 20 to<br />

30 seconds to complete.<br />

For VC-SUMPT, this <strong>test</strong> is known as the VC-SUMPT Port NPE Crosstalk Test (#6). It is a<br />

slightly modified version of the NPE Crosstalk Test<br />

This <strong>test</strong> runs on the following maintenance objects:<br />
