SPA9000 Voice System Installation and Configuration Guide for Web UI
The Local Area Network (LAN) is the communication platform used by the
SPA9000 Voice System for allowing communications among the telephone users
and between the telephone users and the external VoIP, PSTN or/and ISDN
network services. This LAN is composed of the data wiring (UTP cabling),
networking equipment (switches and routers/access device) and the
telecommunication (PSTN or ISDN) lines.
The Local Area Network (LAN) may be already installed or it can be installed and
configured at the time of installing the SPA9000 Voice System. Below are the
general recommendations to ensure proper operation of the SPA9000 Voice
System.

Infrastructure, Cabling and PSTN/ISDN Lines

•
AC outlets: Ensure there is an AC outlet available for every LAN and Cisco SPA
component that requires AC power. If you are using a Power over Ethernet
switch, SPA9x2 phones do not require an AC outlet as they are powered by the
switch.
•
Ethernet cabling: Ensure there is a Ethernet cabling system and that there is an
outlet for each Cisco SPA device. It is recommended that Ethernet cables are
UTP CAT 5e or better.
•
PSTN and ISDN lines: Ensure that the lines are operative and that any features,
such as caller identification, operate properly before starting the installation.
Ensure that the cables are available in the location where you are installing the
Cisco SPA devices.
•
UPS: If you are using an Uninterrupted Power Supply (UPS) mechanism, ensure
that the SPA9000 Voice System design is covered by securing the router and
switch AC connections and the Cisco SPA devices and by using the Power
over Ethernet adapter (POES5) for the non-POE products (SPA9000, SPA400,
SPA9x1 phones). Also ensure that devices such as the WAN modem, CSU/
DSU, or DDS modem are connected to the UPS.
