This appendix provides cable pinout descriptions for the Cisco 4000 series routers.
Following are the signal summaries contained in this appendix:
The cables available from Cisco meet FCC part 15J Class A requirements and Verband Deutscher Electrotechniker (VDE) 0871 Limit B levels. When constructing your own cables, refer to the appropriate documentation regarding interference considerations and cable length limitations.
Refer to Table A-1 when assembling an EIA/TIA-232 console cable or auxiliary port cable for the Cisco 4000-M and to Table A-2 when assembling an EIA/TIA-232 console cable or auxiliary port cable for the Cisco 4500-M and Cisco 4700.

All interface types except EIA-530 are available in DTE or DCE format: DTE with a plug connector at the network end and DCE with a receptacle at the network end. V.35 is available in either mode with either gender at the network end. EIA-530 is available in DTE only.
The tables that follow list the signal pinouts for both the DTE-mode and DCE-mode serial port adapter cables for each serial interface type.
Figure A-1 shows the dual serial module EIA/TIA-232 cable assembly. Table A-3 lists the DTE and DCE pinouts.

For the CT1, two standard T1 serial cables are available from Cisco Systems: null-modem and straight-through. A straight through cable connect your router to an external CSU. Null modem cables are used for back-to-back operation and testing.
The cables have male 15-pin DB connectors at each end to connect the CT1with the external CSU.
The T1 interface cable has two 15-pin DB connectors at each end to connect the CT1with the external T1 CSU. Figure A-13 shows the T1 interface cable, connectors and pin-outs.
Figure A-13 T1 Interface Cable
The T1 interface cables have two, male, 15-pin DB connectors (one at each end) to connect the CT1 with the external CSU. Table A-22 lists the pinouts for the null-modem T1 cable and Table A-23 lists the pinouts for the straight-through T1 cable.
