18.1 Overview

This chapter shows you how to manage outside lines on the X2002.
The following diagram shows the X2002 connected to the various types of outside
connections:
• FXO/PRI/BRI Trunk (A): shows the X2002 connected to the PSTN (Public Switched
Telephone Network) or ISDN (Integrated Service Digital Network) via an FXO/PRI/BRI
port on the X2002. You can also use the FXO ports to connect to a traditional analog PBX,
use the PRI port to connect to a primary rate interface, use the BRI port to connect to a
basic rate interface, if your organization has one. You must have an FXO/PRI/BRI
interface card installed on the X2002 to configure these connections.
• SIP Trunk (B): shows the X2002 connected to a SIP gateway at your VoIP service
provider (ITSP: Internet Telephony Service Provider). You can use the SIP trunk to
connect to a SIP gateway on which you have an existing SIP account.
• Trusted Peer (C): shows the X2002 connected to another X2002 (for example, at your
branch office). You can establish a trusted peer connection with another SIP server that
lists your X2002 as a trusted peer.
