REQUIREMENTS/SPECIFICATIONS
2-3
In some installations, existing UTP building wiring can be used for
token ring cabling.
DO NOT
connect UTP cabling to any non-token
ring network conductors (telephone, etc.) or ground. If in doubt,
test wiring before using.
WARNING:
Telephone Battery and Ringing voltages, used in UTP
telephone circuits, could present a shock hazard and can damage token
ring equipment when connected to token ring cabling.
Type 3 Media Filter
When connecting token ring devices that are not equipped with a
Type 3 Media Filter to either of the active UTP concentrator
modules (TRMIM-22A/24A), a Type 3 Media Filter, such as the
Cabletron Systems TRMF or TRMF-2, must be installed in line with
the lobe cable at the connection to token ring station.
STP CABLE TYPES
Both STP (TRMIM-42A & 44A) concentrator modules support IBM
Type 1, 2, 6, and 9 STP cabling as described in Table 2-2. STP cabling
must conform to the limits shown in Table 2-3.
