Cisco Media Gateway Cable Specifications
Overview
This appendix provides the following cabling and pinout information for the Cisco universal access servers:
•
Console and Auxiliary Port Cables and Pinouts for Access Servers
• Ethernet Port Pinouts
• T1/PRI and E1/PRI Card Port Pinouts
• T1/PRI and E1/PRI Card Cable Assemblies and Pinouts
Note This appendix specifies pinouts only for the pins used. Pins not listed in the tables in this appendix are not connected.
Console and Auxiliary Port Cables and Pinouts for Access Servers
The access server arrives with a console and auxiliary cable kit, which contains the cable and adapters you need to connect a console (an ASCII terminal or PC running terminal emulation software) or modem to your access server. The console and auxiliary cable kit includes:
•RJ-45-to-RJ-45 rollover cable. (See the next section, " Identifying a Rollover Cable," for more information.)
•RJ-45-to-DB-9 female DTE adapter (labeled TERMINAL).
•RJ-45-to-DB-25 female DTE adapter (labeled TERMINAL).
•RJ-45-to-DB-25 male DCE adapter (labeled MODEM).
For console connections, proceed to the "Console Port Cables and Pinouts" section; for modem connections, proceed to the "Auxiliary Port Signals and Pinouts" section.
Identifying a Rollover Cable
You can identify a rollover cable by comparing both ends of the cable. Holding the cables side-by-side, with the tab at the back, the wire connected to the pin on the outside of the left plug should be the same color as the wire connected to the pin on the outside of the right plug. (See Figure A-1.) If your cable was purchased from Cisco Systems, pin 1 will be white on one connector, and pin 8 will be white on the other connector (a rollover cable reverses pins 1 and 8, 2 and 7, 3 and 6, and 4 and 5).
Figure A-1 Identifying a Rollover Cable
Console Port Cables and Pinouts
Use the RJ-45-to-RJ-45 rollover cable and the RJ-45-to-DB-9 female DTE adapter (labeled TERMINAL) to connect the console port to a PC running terminal emulation software. Figure A-2 shows how to connect the console port to a PC. Table A-1 lists the pinouts for the asynchronous serial console port, the RJ-45-to-RJ-45 rollover cable, and the RJ-45-to-DB-9 female DTE adapter (labeled TERMINAL).

Use the RJ-45-to-RJ-45 rollover cable and RJ-45-to-DB-25 female DTE adapter (labeled TERMINAL) to connect the console port to a terminal. Figure A-3 shows how to connect the console port to a terminal. Table A-2 lists the pinouts for the asynchronous serial console port, the RJ-45-to-RJ-45 rollover cable, and the RJ-45-to-DB-25 female DTE adapter (labeled TERMINAL).

Auxiliary Port Signals and Pinouts
Use the RJ-45-to-RJ-45 rollover cable and RJ-45-to-DB-25 male DCE adapter (labeled MODEM) to connect the auxiliary port to a modem. Figure A-4 shows how to connect the auxiliary port to a modem. Table A-3 lists the pinouts for the asynchronous serial auxiliary port, the RJ-45-to-RJ-45 rollover cable, and the RJ-45-to-DB-25 male DCE adapter (labeled MODEM).
