Relocation of Port Circuit Packs
With the possible exception of a port circuit p ack in slot “01” of c arrier “A” that
must be moved for a TN570 Expansion Interfac e, an upgrade to Release 8

does

not
cause port circ uit packs from the Release 5/6si control c abinet to be moved
and manually retranslated. This is bec ause 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 cab inet (with 14 to 16 available port s lots) always
replaces the Release 5/6si control c abinet (with 10 available p ort slots), providing
a net gain of from 4 to 6 port slots.
If a port circuit p ack does reside in slot “ 01” of control cab inet “A,” the STS
software upgrade retranslates this circuit pack to reside in an empty port slot in
the new expansion control cab inet.
For an upgrade to a critic al reliability Release 8r, if a port c ircuit pack resid es in
slot “02” of port c abinet “B,” the STS software upgrad e retranslates this circuit
pack to occ upy another empty port slot in the new expansion control cab inet.
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 occ upy another empty port slot in the new expansion control cab inet.
To ensure reliable DS1 timing in the upgraded Release 8r system, the STS
software upgrade reloc ates the DS1 circuit packs se rving as the primary and
secondary timing sources to occup y 2 empty port slots in the new Release 8r
PPN.
When connecting adjunc ts to an upgrad ed Release 8r, STS locates any new
interface circuit p acks (including TN577 Packet Gateway, TN553 Packet Data
Line, and TN726B Data Line) in the first available slots of th e 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 upgrad ed Release 8r system must conform to the
minimum usable vintage requ irements for Release 8r. Those circuit packs
shipped in the new Release 8r PPN or shipp ed loose with the new EPN
equipment must meet the usabl e vintage specific ations. In addition, at a p resale
site inspection, the remediati on process must chec k the vintages of every
Release 5/6si circuit pack that will be reused with the Release 8r and replace
those circuit pac ks with unusable vintages. Refer to
Technical Quarterly
,
Reference Guide for Circuit Pack Vintages and Cha nge Notices, for current
information about usable vintag es in a Release 8r system.
