UltraWAVE Micro BTS Installation and Commissioning Guide, Version B 49
Connecting E1 or T1 Trunk Cables
Figure 2-19 illustrates the pinout for the RJ-48C to DSUB 120 Ohm conversion
cable.
2.6.2 T1 Cables
T1-100 Ohm
For T1 connections, the proper cable is an individually shielded twisted pair with
a nominal impedance of 100 Ohm +/-5% at 772 kHz. The maximum allowable
cable distance depends directly on the insertion loss of the cable at 772 kHz. The
T1 card can accommodate up to 9 dB of cable loss. When using 22 AWG ABAM
cable, 9 dB of loss is approximately 2000 feet. When using Belden type 9729 (with
a cable loss of 6 dB per 1000 feet at 772 kHz) the maximum cable distance is
approximately 1500 feet.
Table 2-11 provides a description of cables required for installation and
connection to a T1 network, but not supplied with the Micro BTS.
Figure 2-19: 120 Ohm Conversion Cable
Before connecting T1 lines to the Micro BTS, it is assumed that
the quality of the lines has been verified. It is recommended that
BER tests be completed to ensure that the BER is less than 10
