Proxima Rack
With modem management system
The easiest and safest way to implement a
high speed modem pool in your network !
Bausch Datacom nv/sa has developped a 19" modem rack system based on the Proxima modem technology.
High performance and reliability are the key features of this Proxima modem technology.
However ... even the best modem sometimes "hangs".
A Modem Management System - MMS - was integrated in the Proxima Rack.
The MMs contains a backplane whitch fits in the 19" rack. To this backplane 18 Modem Management
Interfaces - MMI - are connected, so each MMI has its own Proxima rack modem to control.
To control all the functions of the MMS a Modem Management Unit - MMU - has been developped.
The network manger controls the MMS via the MMU through a serial terminal port which can be connected
to a modem or a terminal server. The MMU is controlled with simple ASCII commands and result codes.
Typical Applications
Internet
Intranet
Bulletin Board Systems
Dial-out modem/fax pool
Dial-in modem/fax pool
Modem concentrator

The MMS is a high performance modem management
system. One MMs system can control and check up to
18 modems in the same 19" rack. It's possible to
cascade up to 32 racks, so a maximum of 576 modems
can be controlled and checked through one serial
connection.
° max. 18 modems in one rack
° max. 32 racks in cascade
° each modem can be selected through the MMU port
° each modem is controlled and checked by a local
microprocessor on its MMI
° real time statistics for the V.24 signaling for each
modem
° error situations can be detected and reported automatically in a log with a real time clock
° automatic reset and shut down of non answering
modems (after problem detect)
° disconnects (set busy) unused telephone lines
° the initialisation string can be sent to all modems
with one command
° Fail save design :
- each MMU rack is self supporting
- modems can be replaced without disturbing the
other modems
- if one of the cascaded racks fails, the other racks
will keep functioning
° Proxima rack parts:
- 19" Eurorack with backplane
- power supply
- MMU backplane
- MMU master controller
- 18 MMI controller units
- 1 to 18 Proxima rack modems
- manual and cables
