Introduction 543
SmartWare Software Configuration Guide 44 • FXO port configuration
Introduction
This chapter provides an overview of POTS signaling and SmartNode FXO ports and describes the tasks
involved in configuring FXO ports in SmartWare.
This chapter includes the following sections:
• Shutdown and enable FXO ports (see page 543)
• Bind FXO ports to higher layer protocols (see page 544)
• Configure country specific FXO port parameters (see page 544)
• Configure other FXO port parameters (see page 544)
FXO stands for foreign exchange office and is the subscriber side of a POTS (plain old telephone system) line.
An FXO port on the SmartNode simulates thus an analog phone set, which must actively go on-hook and off-
hook, detect ringing and caller-id, and dial the called-party number using DTMF keypad.
Shutdown and enable FXO ports
FXO ports are enabled by default. They also can be configured when they are active. But keep in mind that
configuration of an active port temporarily disables the port for a short time (some milliseconds).
Mode: Configure
Bind FXO ports to higher layer applications
An FXO port needs to be associated to an fxo interface in a CS context. The same mechanism of encapsulation
and binding is used as known for e.g. ethernet ports (see section “Interfaces, Ports, and Bindings” on page 47).
Procedure: To bind an FXO port to an fxo interface of a CS context
Mode: Port FXO
Step Command Purpose
1 (config)#port fxo slot port Enter FXO port configuration mode
2 (prt-fxo)[slot/port]#shut-
down
Shutdown the port. All active calls are dropped!
3 (prt-fxo) [slot/port]#no shut-
down
Activate the port.
Step Command Purpose
1 node(config)#port fxo slot port Enter configuration mode for FXO port
2 node(prt-fxo)[slot/port]#encap-
sulation cc-fxo
Sets the encapsulation for the port. cc-fxo designs
the encapsulation is a context CS interface
3 node(prt-fxo)[slot/port]#bind
interface interface
Binds the port to an interface in a CS context
