26.16 DTU/MDF Twisted Pair Cable – TSRNB 101 50 or AWS1034 (T1 - 100 ohm)
The DTU/MDF twisted pair cable AWS1034 (see Figure 26–19) consist of a 100 ohm shielded
cable terminated with two connectors. The cable is used to connect a DTU to a MS or PBX via a
MDF (Main Distribution Frame). The shielding of the cables is connected to the cabinet via a
clamp which also functions as a strain relief. The length of the cable is 16 ft. Excess cable length
may be trimmed at installation.
The TSRNB 101 50 cable is terminated at one end in 2 RJ45 connectors. These should be cut off
to allow for punch down.
