Connecting an FXO Line
Use a straight-through RJ-11 cable to connect the Foreign Exchange Office (FXO) voice port to the 
PSTN or PBX through a telephone wall outlet.
WarningHazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF 
or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, 
detach the end away from the unit first. Statement 1026
To connect the FXO line, follow these steps:
Step 1Connect one end of the straight-through RJ-11 cable to the FXO port. See Figure 3-22.
Figure 3-22 Connecting an FXO Line
Step 2Connect the other end of the RJ-11 cable to a telephone wall outlet.

  Connecting a Voice ISDN BRI Line
NoteIf you have specified the use of a private line automatic ringdown (PLAR) off-premises extension (OPX) 
connection mode for an  FXO voice port (with loop resistance less than 8000 Ohm), you must ensure 
that the soft-offhook option is enabled on the port.
 
 
This option allows a stepped offhook resistance during seizure which avoids overloading the circuit 
during offhook in the event that ringing voltage is present on the circuit at the same time as the trunk 
seizure. The stepped offhook resistance is initially set to 800 Ohms, then adjusts to 50 Ohms when 
ringing voltage is not present.
 
 
To  e n a b l e  soft-offhook command on the port, and to access the connection command with plar opx 
syntax, see the Cisco Command Lookup Tool.
Connecting a Voice ISDN BRI Line 
Use a straight-through RJ-45 cable to connect the voice BRI port to the ISDN network through a 
telephone outlet or other device. 
CautionTo prevent damage to the router, be sure to connect the BRI cable to the BRI connector only, and not to 
any other RJ-45 connector.
To connect the voice BRI line, follow these steps:
Step 1Connect one end of a straight-through RJ-45–to–RJ-45 cable to the Voice BRI port.
NoteWhen the interface is configured as NT and is connecting to a TE device, use a crossover cable. 
See Ta b l e A-11.

Initial Configuration
This chapter provides instructions for initial configuration of the Cisco 860 series,  880 series, and 890 
series Integrated Services Routers (ISRs). For the initial configuration, we recommend using 
Cisco
 Configuration Professional (CP) Express. Cisco CP Express is a web-based graphical user 
interface that guides you through initial configuration. 
You may also initially configure your router by using the Cisco IOS command-line interface (CLI) or by 
using the setup command facility. To create the initial configuration, the setup command facility prompts 
you for basic information about your router and network. 
This chapter contains the following sections:
 Cisco Configuration Professional Express, page 4-1
 Cisco IOS CLI, page 4-1
 Setup Command Facility, page 4-3
 Verifying the Initial Configuration, page 4-5
 Initial Configuration of the Wireless Access Point, page 4-5
NoteSome SKUs may not include a default configuration file. If your router does not have a default 
configuration file, go to the 
“Setup Command Facility” section on page 3 to configure the initial router 
settings.
Cisco Configuration Professional Express
After you connect the cables and power up the router, we recommend that you use the Cisco CP Express 
web-based application to configure the initial router settings.
For instructions on how to use Cisco CP Express to configure the router see the Cisco CP Express User’s 
Guide.
Cisco IOS CLI
To configure the initial router settings by using the Cisco IOS CLI, you will need to set up a console 
connection. For instructions on how to set up a console connection, see the 
“Connecting a Terminal or 
PC to the Console Port” section on page 3-7.

Step 6Verify the initial configuration. See the “Verifying the Initial Configuration” section on page 4-5.
Setup Command Facility
The setup command facility guides you through the configuration process by prompting you for the 
specific information that is needed to configure your system. Use the setup command facility to 
configure a hostname for the router, to set passwords, and to configure an interface for communication 
with the management network.
To use the setup command facility, you will need to set up a console connection with the router and enter 
the privileged EXEC mode. 
NoteFor instructions on how to set up a console connection, see the “Connecting a Terminal or PC to 
the Console Port” section on page 3-7.
To configure the initial router settings by using the setup command facility, follow these steps:
Step 1Set up a console connection to your router, and enter privileged EXEC mode. For instructions on how to 
enter privileged EXEC mode, see 
Step 1 through Step 4 in the “Cisco IOS CLI” section on page 4-1.
