INTRODUCTION Multiple Concentrator Modules Several concentrator modules can be installed into a single MMAC and configured as independent rings or linked together into a single ring network. Configuration guidelines can be found in Chapter 3, Installing the Concentrator Module. Multiple MMACs in a Ring Network Several MMACs can be connected into the same ring network by installing token ring concentrators (TRMIM-10R/20R with externally accessible Ring-In/Ring-Out ports) or token ring repeaters... -

2.1.1 Cable Specifications The media used for station (lobe) cabling depends on your specific concentrator module: • The TRMIM-22 and TRMIM-24 support voice grade UTP cable, as described in EIA Standard Proposal No. 1907-A, and IBM Type 3 UTP cabling. •... - Page 11 When connecting token ring devices that are not equipped with a Type 3 Media Filter to either of the active UTP concentrator modules (TRMIM-22/24), a Type 3 Media Filter, such as the Cabletron Systems TRMF (see Figure 2-1) or TRMF-2, must be installed in line with the lobe cable at the connection to token ring station.
- Page 12 REQUIREMENTS/SPECIFICATIONS STP CABLE TYPES Figure 2-1. Cabletron Systems TRMF Both STP (TRMIM-42 & 44) 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. Table 2-2.
- Page 13 REQUIREMENTS/SPECIFICATIONS Attenuation and Impedance The maximum attenuation for specific STP cable types is shown in Table 2-3. The attenuation values include the attenuation of the cables, connectors, patch panels, and reflection losses due to impedance mismatches in the segment. Table 2-3. STP Cable Specifications Frequency Impedance Types 1 &...
- Page 14 REQUIREMENTS/SPECIFICATIONS Mixed Cable Types - If you mix cable types in your installation, you must compensate for the different cable attenuations. Type 6 and Type 9 cables can be run for only 2/3 the distance of Type 1. This means: 10 meters (Type 1) Sample Problem: Determine the maximum length for mixed cabling installation...
- Page 15 REQUIREMENTS/SPECIFICATIONS In addition to complying with the preceding cable specifications, the following recommendations should be followed to minimize errors and help to obtain optimum performance from your network: • UTP cabling should be free of splices, stubs or bridged taps. •...

REQUIREMENTS/SPECIFICATIONS 2.2 MAXIMUM NUMBER OF STATIONS The maximum number of stations in a single ring, using STP lobe cabling is dependent on the ring speed. At 4 Mbit/s, up to 250 stations can be connected. At 16 Mbit/s, up to 136 stations can be connected. - Page 17 REQUIREMENTS/SPECIFICATIONS The shield continuity is maintained by contacts within the female RJ-45 that contact the metallic casing of the male RJ-45 on the STP lobe cabling. Shielded patch cables that adapt a shielded RJ-45 to a Data Connector (MIC) are available from Cabletron Systems in eight foot lengths.
