Professional communication devices 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 … BAUSCH DATACOM Doc. ref.

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 BAUSCH DATACOM Doc. ref.
