Network Management System (NETMan)

MICOM’s NETMan is a software package for PCs that manages Marathon networks. This product comes in two versions: NETM- an I (manages up to ten nodes) and NETMan III (manages more than ten nodes and up to 254 networks). A node, in this case, is a NETMan-managed Marathon unit or a MICOM multiplexer. With NETMan, you can monitor, configure, diagnose, and gather statistics for your Marathon networks. NETMan requires SCO UNIX System V/386 Release 3.2 Operating System Version 4.0 or later.

Expansion Card: Model 5000E/6DMA

This module’s primary functionality is for the new Marathon 10K. For the Marathon 5K, it can serve as a six-channel async/sync data expansion module. This module is scheduled for release later this year.

X.21 bis Support for Muxes

X.21 bis is a type of dynamic link required for use in Scandina- vian, German, Japanese and other networks. Unlike the Inter- connect and Mux links (leased line links) which are permanently connected, X.21 is a pay-as-you-go link. X.21 bis is designed to support data-only muxes (MICOM_BOX and LCi/_Val-U-Mux).

Two New Sync Protocols

The new sync protocol options, RTS/CTS and Sync- Pad, offer more efficient use of bandwidth for byte- oriented protocols, which previously required the TDM or Fast Packet (formerly called transparent) options.

APPENDIX H: Additional Information

Async Channel Parity Conversion

The Marathon now converts mark, space, even, and odd parity and matches it to the required output. A terminal can now access several hosts in the network regardless of the host’s parity. Marathon parity now applies to data and messages. (Parity is not converted on feeder muxes.)

4.0 Kbps Voice

With Phase 3.0 software comes the ability to configure a 4.0 Kbps voice digitizing rate. This reduces the bandwidth required for voice/fax operation and will allow two voice channels to operate on a 9.6 Kbps link.

Dual Channel ISU: Model 5000I/56-2

The 5000I/56-2 is a dual channel version of the 5000I/56-1 and is applicable for the Marathon 10K only.
