Cabling Specifications for the Universal Access Server
This appendix provides the following pinout information:
Console and Auxiliary Port Signals and Pinouts
The AS5200 comes with a console and auxiliary cable kit, that contains the cable and adapters you need to connect a console (an ASCII terminal or PC running terminal emulation software) or modem to your AS5200. The console and auxiliary cable kit includes the following items:
For console connections, proceed to the section "Console Port Signals and Pinouts" later in this appendix; for modem connections, proceed to the section "Auxiliary Port Signals and Pinouts" later in this appendix.
You can identify a roll-over cable by comparing the two modular 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 C-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 (a roll-over cable reverses pins 1 and 8, 2 and 7, 3 and 6, and 4 and 5).
Figure C-1 : Identifying a Roll-Over Cable
Console Port Signals and Pinouts
Use the RJ-45-to-RJ-45 roll-over cable and RJ-45-to-DB-9 female DTE adapter (labeled Terminal) to connect the console port to a PC running terminal emulation software. Figure C-2 shows how to connect the console port to a PC. Table C-1 lists the pinouts for the asynchronous serial console port, the RJ-45-to-RJ-45 roll-over cable, and the RJ-45-to-DB-9 female DTE adapter (labeled Terminal).

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

Dual E1 PRI Card Cable Assemblies and Pinouts
Four serial cables are available from Cisco Systems for connecting the E1 PRI card ports. All four have DB-15 connectors on the E1 end and either BNC, DB-15, twinax, or RJ-45 connectors on the network end. Figure C-6, Figure C-7, Figure C-8, and Figure C-9 show the E1 interface cables. Table C-6 lists the pinouts for the E1 interface cables connecting to the Dual E1 PRI card.
