Shielded patch cables that adapt a shielded RJ-45 to a Data
Connector (MIC) are available from Cabletron Systems. These
adapter/patch cables permit connecting to an existing patch panel
equipped with data connectors (see Figure 2-3).

A Type 3 Media Filter (see Figure 2-4) is required for each of the
stations connected to the TRRMIM-2AT. The Type 3 Media Filter
provides impedance matching from the Type 3 (UTP) lobe cabling
to the Type 1 (STP) interface provided with many token ring
stations. In some token ring stations the media filter is integrated
into the station.
