Connecting an FXS Line
Use a standard straight-through RJ-11 modular telephone cable to connect a Foreign Exchange Service 
(FXS) port to a telephone or fax machine.
WarningThis equipment contains a ring signal generator (ringer), which is a source of hazardous voltage. Do 
not touch the RJ-11 (phone) port wires (conductors), the conductors of a cable connected to the RJ-11 
port, or the associated circuit-board when the ringer is active. The ringer is activated by an incoming 
call. Statement 1042
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
WarningFor connections outside the building where the equipment is installed, the following ports must be 
connected through an approved network termination unit with integral circuit protection: FXS.

To connect the FXS line, follow these steps:
Step 1Connect one end of the straight-through RJ-11 cable to the FXS port.
Figure 3-36 shows an FXS line connection.

Step 2
Connect the other end of the cable to the RJ-11 port on the fax machine or telephone.
Connecting an FXO Line
Use a straight-through RJ-11 cable to connect the FXO voice port to the PSTN or PBX through a 
telephone wall outlet.1FXS port3RJ-11 port

Step 2
Connect the other end of the RJ-11 cable to a telephone wall outlet.
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.1FXO port3Telephone outlet

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 enable the 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 - 2 7.

Statement 1040
WarningInvisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do 
not view directly with optical instruments. Viewing the laser output with certain optical instruments 
(for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm may pose an eye 
hazard. Statement 1056
WarningUse of controls, adjustments, or performing procedures other than those specified may result in 
hazardous radiation exposure. Statement 1057
