Migrating a DEFINITY Server R to an S8700-Series Media Server
760 Upgrading, Migrating, and Converting Media Servers and Gateways
Replacing the tone clocks with TN2312BP IPSI circuit packs in the
expansion port networks and the processor port network
(optional)
Some PNs receive IPSI circuit packs. The TN2312BP Internet Protocol Server Interface (IPSI)
circuit pack takes the place of the existing TN2182 Tone Clock circuit pack and terminates
control communication with the S8700-Series Media Servers. In existing PNs that receive
IPSIs, flat ribbon cables run between the IPSIs and the maintenance circuit pack. These ribbon
cables provide connectivity that is unavailable by the backplane of older carriers. Once the IPSI
circuit packs are installed, you must either:
● Program the faceplate so a DHCP server can assign IP addresses to the IPSIs
● Program static IP addresses into the IPSI, depending on whether the control network is
dedicated (private) or nondedicated. Nondedicated means through the customer network.
You can complete this stage at any time before the cutover. The tone clock and the IPSI circuit
packs are hot swappable, and you replace the circuit packs in the existing DEFINITY system
without the need to turn off the power. The IPSI circuit pack provides the same functionality as
the tone clock circuit pack. The IPSIs can be connected by CAT5 cable to the media server
complex by the Ethernet switch before the cutover. You can do this while the IPSIs are working
as tone clocks in the existing system. With this connection, you can test connectivity between
the media servers and the IPSIs before the cutover. Even though you are converting the PPN to
a PN, Avaya recommends that you install the IPSIs in the PPN and test connectivity prior to the
migration. You then reinstall the IPSIs in the new carriers after you install the carriers.
This stage affects service in duplex-reliability configurations. The PNs are out of service while
you replace the circuit packs. To save out-of-service time in high-reliability and critical-reliability
configurations, you can replace the circuit packs in only the standby MCC carriers or SCC
cabinets.
Converting the processor port network to a port network
This stage consists of replacing the processor carrier A in the PPN with a new expansion control
carrier (J58890AF-2 L13). If the PPN has duplicated control carriers or cabinets you also must
replace carrier B with a new port carrier or cabinet.
If you replaced the EIs and maintenance circuit packs and replaced the tone clock with an IPSI
circuit pack in the old control carrier, you must reinsert these circuit packs into the new control
carrier. You do not need to reprogram the IPSI. If the system is critical-reliability and you have a
CSS or an ATM, you must move the EI circuit packs to positions A01 and B02.
You must install and configure the media servers, transfer the translations, and upgrade the
existing PNs before you complete this stage.
