Relocation of Port Circuit Packs
An upgrade to Release 8
does not
cause G2 port circuit packs to be moved and
manually retranslated. This is because a G2 universal module is always
upgraded to an EPN. So, during the upgrade, a Release 8 expansion control
carrier (with 18 available port slots) always replaces the G2 module control
carrier (with no port slots), providing a net gain of 18 port slots.
Usable Circuit Packs
Each circuit pack used in the upgraded Release 8 system must conform to the
minimum usable vintage requirements 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 vintage specifications. In addition, at a presale
site inspection, the remediation process must check the vintages of every G2
circuit pack (including any CFY1 current limiters) that will be reused in the
upgraded Release 8 and replace those circuit packs that have unusable
vintages. Refer to
Technical Monthly
, “Reference Guide for Circuit Pack Vintages
and Change Notices,” for current information about usable vintages in a Release
8 system.
In most configurations, the 2- or 3-circuit pack combination of a tone generator
pack, tone detector pack, and/or call classifier pack can be replaced with the
TN2182 circuit pack, freeing up 1 or 2 port slots.
Since Release 8 supports non-United States call-processing applications, a wide
variety of non-United States circuit packs can be used. Contact your Lucent
Technologies representative for more information.
Site Inspections
For the purposes of a Release 8 upgrade, most G2 systems are already
equipped with the correct TDM/LAN cables (WP-91716 L6 and L7) and the
correct lightwave transceivers (9823A or 9823B). However, some G2 systems
contain earlier versions of these components, and (based on a site inspection)
these older components must be replaced.
The 2 earlier versions of the TDM/LAN cable included the WP-91112 (L1 and L2)
and the WP-91716 (L1 and L2). Both of these versions had white labels. In
contrast, the correct cables (WP-91716 L6 and L7) have blue labels. If a
remediation site inspection reveals that the older cables reside in the system,
replace the older cables under the remediation process.
