Upgrading a Multicarrier G2 Universal Module to Avaya
DEFINITY Server R EPN running Avaya MultiVantage
Software
Relocation of Port Circuit Packs
An upgrade 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, an 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 must conform to the minimum usable vintage
requirements. 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 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 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.
Site Inspections
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.
Earlier versions of lightwave transceivers include the 4-series transceivers (4A
through 4F). These transceivers support fiber connections up to 7,000 feet (2134
m) apart; whereas the 9823A supports connections up to 5,000 feet (1524 m), and
the 9823B supports connections up to 25,000 feet (7620 m). A single mode fiber
transceiver (300A) supports distances of up to 115,000 feet (21.7 miles, 35 km). If
the site inspection reveals that the older 4-series transceivers reside in the
system, Order the correct transceivers according to a separate PEC.
NOTE:
Using the 300A may require 5 or 10 dB attenuators. Contact your Avaya
representative for more information.
