Appendix C — Terminal Port Cable

Some terminals will not transmit data if their CTS (Clear To Send) line is LOW. These terminals must have their CTS line HIGH or floating to ensure that they will have no problems communicating with the T1 Modem Bank. The cable shown in Figure 31 can be used if a terminal of this kind does not require hardware handshaking.
