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. IBM Cable Types
Type 1 Two shielded twisted pairs (STP) of 22 AWG solid wire
for data. Used for the longest cable runs within the
walls of buildings.
Type 2 Similar to Type 1 data cable, but having four
additional unshielded twisted pairs of 22 AWG solid
wire. These are carried outside of the shield casing
and are typically used for voice communication.
Frequently used to wire cable runs within the walls of
buildings.
Type 6 Two STP of 26 AWG stranded wire for data. This type
is used in patch panels or to connect devices to/from
wall jacks. Attenuation for Type 6 cable is 3/2 x Type
1 cable (66 m of Type 6 = 100 meters of Type 1).
Type 9 Similar to Type 1, but uses 26 AWG solid wire.
Attenuation for Type 9 cable is 3/2 x Type 1 cable (66
m of Type 9 = 100 meters of Type 1).
