Figure 2: Sample S8700 or S8710 MBS configuration
Translations must be saved only on the primary media server(s) because scheduled transfers of the
translations via script to the MBS occur automatically and overwrite any translations temporarily saved
on the MBS. No transfers take place from the MBS to the primary media server(s).
When a failure occurs, the customer activates the MBS, allowing it to take over. This also means that
when the problem rectifies itself, the customer must bring the primary media server(s) back on line as
soon as possible after deactivating the MBS.
NOTE:
If Local Survivable Processors (LSPs) exist on the system, the LSPs likely become active
before the customer manually brings up the MBS. In this case, a customer has gateway
locations that are controlled by LSPs independent of an MBS being active. As part of the
switchover, to establish control of the LSPs by the now active MBS, the LSPs must be
reset.
Avaya Communication Manager software is disabled by default on the MBS; therefore, after a reboot, the
MBS will not start call processing nor have control of any port network resources.
General operation of the MBS requires removing the file that allows Avaya Communication Manager to
start automatically when MBS reboots. Installation of the MBS also requires enabling anonymous ftp by
default on the MBS, which implies that the use of ftpserv on the MBS must cease. This environment must
be reestablished after any server configuration changes or software upgrades that affect the MBS.
All changes described above must be made by Avaya Services as part of the implementation process due
to root access requirements.
