High-Level Overview - Avaya S8700 Series Manual

High-level overview

Note:
This section applies to the S8700 or S8710 Multi-Connect configuration only.
Note:
The migration from a DEFINITY ECS R or SI platform to the Avaya S8700 or S8710 Media
Server with Avaya G650 Media Gateway (S8700 or S8710 Multi-Connect configuration) may be
done in stages. The order in which these stages are completed, in most cases, depends on the
resources available, the personnel available to perform them, and the customer's desire to
minimize downtime. There needs to be careful coordination with the customer, as some of the
operations required are service affecting.
The recommended process is based on several assumptions:
The TN2312BP IP Server Interface (IPSI) circuit packs are installed ahead of time in the
expansion port networks (EPNs) and processor port network (PPN—optional).
Most PPNs may contain an IPSI, particularly for direct-connect systems.
The general process is the same regardless of reliability.
The high level stages are:
Install and configure the S8700 or S8710 Media Server complex.
Transfer existing DEFINTY translations to Avaya Communication Manager residing on the
S8700 or S8710 Media Servers. Add new translations for the IPSI circuit packs.
Replace expansion interface and maintenance circuit packs in all the existing DEFINITY
ECS port networks (PNs) with upgraded circuit packs (TN570B, vintage 7, or later;
TN775D).
Replace tone clocks with TN2312BP IPSI circuit packs in the designated EPNs and PPN
(optional).
Convert the PPN to a PN.
Cut over to S8700 or S8710 Media Server control.
Complete the migration steps, such as enabling alarm reporting and registering the
system.
Test the S8700 or S8710 Multi-Connect configuration.
The order that the high-level stages are listed above represents a recommended sequence to
follow. Some of the stages can be done in a different sequence without causing any negative
consequences. Local practice and resource management dictates the actual sequence.
