Notes:
a. The fiber is in frame, but no communication exists to the neighbor.
b. This is the normal state for an active PN EI circuit pack that is also the bus
master (expansion Archangel) in the PN.
c. This is the normal state for an active EI circuit pack that is not the bus
master (expansion Archangel) for an PN. This applies only in the direct
connect configuration where the EI circuit pack in an PN connects via a
fiber link to an EI circuit pack in the other PN. This state also applies for an
active EI circuit pack located in the PN.
d. This is the normal state for a standby expansion Interface circuit pack in
the PN.
For more details about how the EI circuit pack error codes relate to the LED
states, see ‘‘EXP-INTF (Expansion Interface Circuit Pack)’’ on page 8-762.
Notes:
a. A Fiber is out of frame or a fiber loss-of-signal condition exists.
b. DS1 CONV/fiber endpoint communication is down.
c. The DS1 channel is down between the two DS1 CONVs in the DS1
converter complex.
