2. Introduction
The Twin Mux Repeater Module is a hot-swappable 8-port multiplexor for
the Power Cage 500 Solution (RM601A) for use in the IBM®S/3X or AS/400®
environment.
The Twin Mux Repeater Module lets you combine eight host ports over
one fiber, UTP, or STP cable pair for more cost-effective cabling installations.
Distances of up to 2500 feet (762 m) via UTP or 8200 feet (2500 m) via fiber
may be achieved between one Twin Mux Repeater Module and another. Up
to eight Twin Mux Repeater Modules may be housed in one Power Cage for
a total of 64 host ports.
True repeater technology restores signal timing, amplitude, and frame
information damaged by other peripherals. Because its a repeater, the Twin
Mux Repeater Module can be cascaded with other booster or repeater-based
products.
For added security, the Twin Mux Repeater Module has a redundant
multiplex port that may be used as a backup in case of a link failure.
If the primary link fails, the second port maintains communication
without disrupting the users.
The Twin Mux Repeater Module can be configured as a controller-side
multiplexor/demultiplexor (Ctrl Mode) or as a workstation-side
multiplexor/demultiplexor (Term Mode) via DIP-switch control.
The Twin Mux Repeater Module integrates seamlessly with the Multiple
Twinax Repeater III (IC106C) star wiring hub for total cabling solution.
Or, it can allow seven workstations to be daisychained to each of the eight
workstation ports of the terminal-side Twin Mux Repeater Module. One pair
of modules can support up to forty AS/400 twinax devices via a single cable
pair.
The Twin Mux Repeater Module automatically checks polarity and line
sync. LED diagnostics indicate if a true IBM System 3X or AS/400 signal
is received in the correct polarity, and also analyzes the data on the line
to check for parity errors.
The Twin Mux Repeater Module may be used with patch panels,
punchdown blocks, and other premise-wiring products for improved
cable management.
