Console and Auxiliary Port Cables and Pinouts
Your Cisco VG350 Voice Gateway comes with the cable and adapters you need to connect a PC, an ASCII terminal, or a modem to your Cisco VG350 Voice Gateway. The cable kit includes:
•
•
•
The following illustrations and tables provide cable pinout information:

Alternative Connections to Terminal and Modem
Your Cisco VG350 Voice Gateway ships with an RJ-45-to-RJ-45 rollover cable and two adapters for connection to a PC, a terminal, or a modem. If you want to use an RJ-45 straight-through cable or other adapters, see Table A-4 for usable cable and adapter combinations.
