Modems in Powercluster Configurations
RSF (Remote Services Facilities) performs system error monitoring and handles
communications for remote maintenance operations. The modem, together with RSF,
provide a link, via a phone line, between the system at the customer site and a Bull
Customer Service.
The table below shows the number of modems and their type, according to the
Powercluster configuration.

The modem is an external modem if it is connected to an EPC800 or an
EPC1200/EPC1200A/EPC440 node. For plugging the external modem to the serial port S2,
a CBL1912 cable adapter (provided with the CPU drawer) may be used.
On an EPC400 node, there is an integrated modem (ISA board).
On the PowerConsole (Estrella) the modem is an external box whereas on the
PowerConsole 2 (Escala S Series) the modem (MI DCCG086) is an integrated board.
In any configuration with a console concentrator (CS2600), the modem is either connected
to the PowerConsole or to a particular node. In the latter case, the node must have a 8–port
async board enabling to connect the node to port J9 on CS2600. In pure EPC400,
configurations, the modem is integrated in a node. In other cases, it is an external modem.
For mixed 2-node configurations, two modems are supplied. On an EPC400-N node, the
modem is integrated. On EPC1200-N, EPC1200A-N, EPC440-N and EPC8000-N nodes,
the modem is external.
