Relocation of Port Circuit Packs
With the possible exception of a port circuit pack in slot “01” of carrier “A” that
must be moved for a TN570 Expansion Interface, an upgrade to Release 8
does
not
cause port circuit packs from the Release 5/6si control cabinet to be moved
and manually retranslated. This is because a Release 5/6si PPN is always
upgraded to an EPN. So, during the PPN upgrade to a Release 8r EPN, a
Release 8r expansion control cabinet (with 14 to 16 available port slots) always
replaces the Release 5/6si control cabinet (with 10 available port slots), providing
a net gain of from 4 to 6 port slots.
If a port circuit pack does reside in slot “01” of control cabinet “A,” the STS
software upgrade retranslates this circuit pack to reside in an empty port slot in
the new expansion control cabinet.
For an upgrade to a critical reliability Release 8r, if a port circuit pack resides in
slot “02” of port cabinet “B,” the STS software upgrade retranslates this circuit
pack to occupy another empty port slot in the new expansion control cabinet.
To provide maximum holdover for a TN750/B Announcement circuit pack that did
not reside in the control carrier, the STS software upgrade relocates this circuit
pack to occupy another empty port slot in the new expansion control cabinet.
To ensure reliable DS1 timing in the upgraded Release 8r system, the STS
software upgrade relocates the DS1 circuit packs serving as the primary and
secondary timing sources to occupy 2 empty port slots in the new Release 8r
PPN.
When connecting adjuncts to an upgraded Release 8r, STS locates any new
interface circuit packs (including TN577 Packet Gateway, TN553 Packet Data
Line, and TN726B Data Line) in the first available slots of the first PPN port
carrier.
NOTE:
To find out where STS relocated these circuit packs, refer to the annotated
‘‘list configuration all" that STS provides with the new Release 8r removable
media.
Usable Circuit Packs
Every circuit pack used in the upgraded Release 8r system must conform to the
minimum usable vintage requirements for Release 8r. Those circuit packs
shipped in the new Release 8r PPN or shipped loose with the new EPN
equipment must meet the usable vintage specifications. In addition, at a presale
site inspection, the remediation process must check the vintages of every
Release 5/6si circuit pack that will be reused with the Release 8r and replace
those circuit packs with unusable vintages. Refer to
Technical Quarterly
,
Reference Guide for Circuit Pack Vintages and Change Notices, for current
information about usable vintages in a Release 8r system.
