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.
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.
