System 75 Small-Cabinet to R8si (Blowback)

This section provides the information necessary to upgrade a small-cabinet R1V3 System 75 system to either a standard-reliability DEFINITY ^® R8si PPN (control-carrier replacement) or a multi-carrier R8si PPN with standard or critical reliability (cabinet replacement).

For further information, see

• Upgrade overview: small-cabinet System 75

Before you begin the upgrade

Review the Preparation and process steps carefully. These tables describe the tasks that must be completed before the upgrade visit and who is responsible for them.

To prevent the most common upgrade problems, be sure that you have

• identified the correct TDM bus cables and terminators for the upgraded system


• verified si expansion interface compatibility for packet bus applications:



If the new si 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.

• checked for software upgrade compatibility and identified any patches that need to be re-applied
