Introduction

This chapter provides an overview of interfaces in the CS context and describes the tasks involved in their con-
figuration. Within the CS context of the SmartWare, an interface is a logical entity providing call signaling for
incoming and outgoing calls to and from ISDN or FXS ports and voice over IP gateways. It represents logical
connections to other equipment or networks. CS interfaces are used as source and destination in the call router
and are bound to physical ports or logical (SmartWare) gateways.
Interface names can be any arbitrary string with a maximum of 25 characters. For ease of identification, the
interface type can be a part of the name.
interfaces are:
• PSTN interfaces (ISDN and FXS). An ISDN interface is used to access the ISDN stack that runs on top of
an ISDN port. Layer 3 (Q.931) of the ISDN stack is bound to this CS interface. Incoming calls from the
ISDN stack are routed by the call router according the route configuration on the ISDN interface. Like-
wise, an FXS interface handles an FXS port, which must be bound to the FXS interface. Binding is done
from a port to an interface.
• VoIP interface (H.323 and SIP). H.323 and SIP interfaces are CS interface types that provide voice over IP
settings in addition to the general CS interface parameters. These interfaces must be explicitly bound to an
existing H.323 or SIP gateway, respectively.
Interfaces can use mapping tables and precall service tables to manipulate call properties before the call is being
offered to the call router.
