Figure 2: TN767/TN464 LEDs
Circuit Pack LEDs
See Table 75: TN767/TN464 circuit pack LED interpretation for a guide to interpreting LEDs on
the TN767 and TN464 circuit packs. In the table, DS1 refers to both DS1 and UDS1.
Note: On
Note:
the TN767/TN464 circuit pack faceplate, loopback indications share the same
LEDs as alarm indications. Loopback indications take priority over alarm
indications. Disregard alarm indications while loopback indications are active. For
example, if the status 2 LED is yellow, indicating a loopback problem, disregard
status 3 and status 4 alarm indications.
