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 an 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 the set expansion-link PCSS command
where PCSS is the address 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 the change circuit-pack P (PN’s number) command.
2. For the EI circuit pack you wish to reset, add an entry to the Circuit Pack
form for the TN776 EI circuit pack. Be sure to enter the appropriate carrier
and slot (that is, A01 or B02).
3. Repeat the reset board command.

Test
Result
Description / Recommendation
ABORT
Internal system error.
1. Retry the command at 1-minute intervals up to 3 times.
4
ABORT
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
ABORT
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. Repeat the reset board PCSS command.
2000
ABORT
Response to the test request was not received within the allowable time period.
2100
ABORT
System resources required to run this test are not available.
1. Retry the command at 1-minute intervals up to 3 times.
