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.

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; 1 in each EPN (Critical Reliability)
Adding ATM PNC connections
Standard Reliability
1. If the ATM PNC EI circuit pack is not present or if the circui t pack is
present but is in an EPN, use the change circuit-pack command to ad d
circuit pack translation.
2. Enter add atm pnc
n
(connection number), and 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.
