Chapter 25 Status Observation
Interface Types
The Status Observation screens allow you to check the current status of several
types of interface.
• SIP Peers refer to the X2002's VoIP extensions, whereas SIP Trunk interfaces
are links to other VoIP servers (these may be located locally, or anywhere else
in the world).
• FXO and FXS interfaces refer to regular analog telephone connections. In the
acronym FXO (Foreign eXchange Office) the term "Office" refers to the
connection's final destination (the telephone company's central office). Thus,
FXO Trunk interfaces lead to the public telephone network. Likewise, in the
acronym FXS (Foreign eXchange Station) the term "Station" refers to the
connection's final destination (the user's analog telephone set). Thus, FXS Peer
interfaces lead to the X2002's analog telephone extensions.
• BRI and PRI are types of ISDN. BRI refers to Basic Rate Interface. Basic Rate
Interface connections are used for connections to the ISDN phone network (BRI
Trunk) and also for connections to user's ISDN telephone sets (BRI Peer). PRI
refers to Primary Rate Interface, which has a much higher capacity than
standard BRI. PRI connections are therefore used only for connections to the
ISDN phone network (PRI Trunk).
