Relocation of Port Circuit Packs
An upgrade to Release 8

does not

cause G 2 port circuit packs to be mo ved and
manually retranslated. This is because a G2 universal module is always
upgraded to an EPN. So, during the upgrade, a Release 8 exp ansion control
carrier (with 18 available p ort slots) always replaces the G2 m odule control
carrier (with no port slots), p roviding a net gain o f 18 port slots.
Usable Circuit Packs
Each circuit pac k used in the upgrad ed Release 8 system must conform t o the
minimum usable vintage requ irements for Release 8. Those circuit packs
shipped in the new Release 8 PPN or shipped loose with the new EPN equipment
should always meet the usable vintag e specificati ons. In addition, at a presale
site inspection, the remediati on process must chec k the vintages of every G2
circuit pack (inc luding any CFY1 current limiters) that will b e reused in the
upgraded Release 8 and replace those circ uit packs that have unusab le
vintages. Refer to

Technical Monthly

, “Reference Guide for Circuit Pack Vintages
and Change Notices,” for current information about usab le vintages in a Release
8 system.
In most configurations, the 2- or 3-c ircuit pack c ombination of a tone generator
pack, tone detec tor pack, and/or c all classifier pac k can be replac ed with the
TN2182 circuit pack, freeing up 1 or 2 port slots.
Since Release 8 supports non-United States c all-processing ap plications, a wid e
variety of non-United States circuit p acks can be used . Contact your Lucent
Technologies representative for more information.
Site Inspections
For the purposes of a Release 8 upgrad e, most G2 systems are already
equipped wi th the correct TDM/LAN cables ( WP-91716 L6 and L7) and the
correct lightwave transc eivers (9823A or 9823B). However, some G2 systems
contain earlier versions of these comp onents, and (based on a site inspection)
these older components must be replaced .
The 2 earlier versions of the TDM/LAN cable includ ed the WP-91112 (L1 and L2)
and the WP-91716 (L1 and L2). Both of these versions had w hite labels. In
contrast, the correct c ables (WP-91716 L6 and L7) have blue lab els. If a
remediation site inspectio n reveals that the older cab les reside in the system,
replace the older c ables under the remediation p rocess.
