| The SLIM-TAU, Trunk Access Unit,
provides physical and electrical connection between workstations and the
Token Ring network. Functioning as a wiring concentrator, it offers
star-shaped ring topology for eight users. For networks larger than
eight users, several SLIM-TAUs can be linked together, by connecting
Ring In/Ring Out expansion ports.
Insert and bypass functions are provided within
the unit. Insertion of a workstation into the ring can be initiated at
any time by simply inserting the data connector. Bypassing of a
workstation is carried out automatically when a data connector is
deinserted from the unit, or when a workstation is inactive.
The SLIM-TAU is available with IBM data connectors
for use in an IBM cabling system environment, unshielded RJ-45 modular
jacks for use with UTP, or shielded RJ-45 modular jacks for use with STP.

Each lobe is equipped with a status LED indicator
which lights when a station is inserted into the ring, simplifying
diagnostics and troubleshooting. A global RESET push button, with a
reset confirmation LED indicator, resets all lobes, eliminating the need
for an additional setup tool. The reset circuitry is operated by a
lithium battery accessible from the back panel.
The SLIM-TAU operates without external power. The
unit is exceptionally compact and lightweight, measuring only 1U (1.75
in) in height and 2.5 cm (1 in) in depth. |
