CSS to R8r ATM-PNC
This section describes the procedures for upgrading a DEFINITY ECS with
center stage switch (CSS) and no previous ATM administration to a Release 8
ATM-PNC. You need separate ATM interface circuit packs (TN2305/TN2306) for
each use.
NOTE:
You can also update a DEFINITY ECS with direct connect to ATM-PNC.
Follow the procedures in Table 4-3
and Table 4-4, but skip the steps
involving removing switch nodes and switch node interfaces.
The basic upgrade process is to
■ Upgrade DEFINITY ECS to Release 8r (refer to upgrade book)
■ Make sure all equipment is on site before the installation
NOTE:
Make sure the ATM switch works before proceeding.
■ Remove the current PNC and fiber links first from the standby carrier then
the active carrier on a PPN, if a duplicated system
■ Remove the PNC and fiber links from the EPNs
■ Administer ATM switch on DEFINITY ECS
■ Power down the cabinets, then remove TDM buses
