UPGRADES AND ADDITIONS
DEFINITY Generic 1 Upgrade to DEFINITY Generic 3r PPN
When upgrading an existing system to a DEFINITY G3r PPN, with or without duplication, only
new shipments of PPNs are supported, so existing cabinets cannot be upgraded regardless of
type. Please note that the PPN of a G3r system is only housed in a multi-carrier cabinet.
DEFINITY Generic 1 PPN Upgrade to DEFINITY Generic 3r
EPN MCC Without Duplication
The DEFINITY Generic 1 PPN multi-carrier cabinet upgrade to DEFINITY Generic 3r EPN MCC
requires the following:
Remove all port circuit packs in the cabinet position A Control Carrier J58890AH. These
will be reused in the carrier replacement.
Remove TN776 Expansion Interface circuit pack (located in port slot 1).
Remove all other control circuit packs. These will not be reused except for TN768 Tone
Clock.
Remove power units (631DA and 631DB for AC systems and 644A and 645B for DC
systems). These will be reused. Also, power units 631AR and 631BR or 631WA and
631WB (AC systems) will work in the G3r, if present. However, if you do reuse the
631AR and 631BR or 631WA and 631WB power supplies, it is required that you reuse
either the TN736 or TN752 Power Converter circuit pack with them.
Remove inter-carrier cables. Only TDM/LAM bus cables (WP-91716) or terminator
(ZAHF4) will be reused.
Replace J58890AH in cabinet position A with Expansion Control Carrier J58890AF in the
cabinet position A. The same cabinet interface cables (wiring harnesses) are reused.
Install two power units (631DA and 631DB for AC systems and 644A and 645B for DC
systems). You can also install power units 631AR and 631BR or 631WA and 631WB as
an alternative. However, if you do reuse the 631AR and 631BR or 631WA and 631WB
power supplies, it is required that you reuse either the TN736 or TN752 Power Converter
circuit pack with them.
Install TN775 Maintenance circuit pack.
Install TN570 Expansion Interface circuit pack in port slot 1.
Install TN768 Tone Clock circuit pack from the DEFINITY Generic 3i.
Port circuit packs that were removed can be reinstalled in the Expansion Control Carrier.
Port circuit packs that must be upgraded for G3r functionality can be installed at this
time. See Table U for a list of the circuit packs and their replacements.
