Expansion Interface Test (#244)
This test is potentially very destructive and requires the EI circuit pack to be busied out prior to
execution of this test.
The Expansion Interface test, which is not a part of either the short or long test sequences, is
executed via reset board PCSS where PCSS is the location of the EI circuit pack to be reset.
If the system only has one working EI link between a pair of port networks and one of the EI
circuit packs must be reset, the action of busying out the desired EI circuit pack WILL DISRUPT
SERVICE TO THE PN until the circuit pack is released from the busyout state. If the circuit pack
is part of a PN-to-PN link, the PN WILL BE WITHOUT SERVICE. If the circuit pack is part of a
PN-to-PN link CALLS BETWEEN THE TWO PNs WILL BE DENIED.
If the system has working duplicate EI links, and the EI circuit pack to be reset is part of the
active EI link, the system does not allow the busyout and instructs system technician to switch
EI links via set expansion-link location where location is the location of either standby
EI circuit pack on the standby link. After executing the EI link switch, it is possible to busyout
and then reset the original EI circuit pack.
However, if the PN’s Maintenance (MAINT) circuit pack determines that the EI (EXP-INTF)
circuit pack is cycling between sane and insane several times within several minutes, MAINT
may inhibit operation of the EXP-INTF by holding the EI circuit pack in a reset state. This
condition may result in an unsuccessful reset of the EI circuit pack.
If the reset command returns with PN is unavailable, execute the following:
1. Use change circuit-pack P (PN’s number).
2. For the EI circuit pack you wish to reset, add an entry to the Circuit Pack screen for the
TN776 EI circuit pack. Be sure to enter the appropriate carrier and slot (that is, A01 or B02).
3. Repeat reset board.

Description / Recommendation
ABRT Internal system error.
1. Retry the command at 1-minute intervals up to 3 times.
4 ABRT Could not reset PN EI circuit pack over optical fiber since PN EI circuit pack
on opposite end of fiber is not inserted.
1. Insert opposite EI circuit pack and perform reset again.
1015 ABRT The system does not allow this test to be run because the EI circuit pack
has not been busied out.
1. Busyout the EI circuit pack. Enter reset board PCSS.
