Verify expansion interface compatibility for packet bus
applications:
If the new system will have one or more expansion port
network cabinets and will run any packet applications, do not
reuse the TN776 expansion interface circuit packs; they must
be replaced with TN570 circuit packs.

4
Identify proper TDM/LAN bus cables and terminators for the
system.
If PACCON is not currently enabled, the cables and
terminators may need to be replaced for V3 and later si
systems, R5/R6vs systems, and SRPs upgrading to Avaya™
Communication Manager.
Packet applications currently running in one port network do
not guarantee that the system has the correct hardware.
Adding a packet application to another network without
verifying the TDM/LAN bus cables and terminators
frequently causes upgrade problems.
We recommend that you schedule a time to replace the cables
and terminators before the upgrade. Note that this requires a
service outage.
