Maintenance Objects
3-145ATM-EI (Expansion Interface Circuit Pack)
3
Critical Reliability
There are 2 ATM-EI circuit packs in the PPN, 2 in the EPN.
1. Enter status pnc at the DEFINITY SAT. If the board is on the active side,
enter reset pnc interchange to switch the active ATM-EI board to the
standby side.
2. Enter busyout pnc-standby.
3. Enter busyout atm-pnc #

a-pnc

or

b-pnc

.
4. Replace the circuit p ack.
5. Enter release atm pnc #.
6. Enter release pnc-standby.
7. Wait 2.5 minutes for board insertion.
8. Enter test board UUCSS and verify that all tests pass.
Basic ATM PNC administration
NOTE:
This section contains basic administration information only. Refer to

DEFINITY ECS Installation, Upgrade, and Administration for ATM

for more
detailed information.
ATM PNC connections involve administering
■1 ATM-EI board in each Port Network (Standard Reliability)
■2 ATM-EI boards in the PPN; 1 in each EPN (High Reliability)
■2 ATM-EI boards in every Port Network (Critical Reliability)
Adding ATM PNC connections
Standard Reliability
1. If the ATM-EI circuit pack is not present or if the c ircuit pack is present b ut
is in an EPN, use the change circuit-pack command to add circuit pack
translation.
2. Enter add atm pnc
n
(connection number), an d administer the circuit
pack location and ATM address.
Critical Reliability
1. Enter change system-parameters duplication and change the Enable
Operation of PNC Duplication field to n.
2. If the ATM-EI circuit pack is not present or is p resent but it is in an EPN that
does not yet have PNC connectivity to it, use the change circuit-pack
command to add circuit pack translat ion for the missing circuit p ack.
