1 INTRODUCTION
This Installation Manual provides the information required for installation, operation and maintenance of the
Ericsson-LG Enterprise iPECS UCM (Unified Communication Manager) system.
For system feature and programming, refer to the iPECS UCM F&O (Feature and Operation) and WMS
Manual provided separately.

2 General Description
This chapter shows the brief description of iPECS UCM, Gateway Modules and Cabinets.
2.1 iPECS UCM Overview
The iPECS UCM is Ericsson-LG Enterprise’s Internet Protocol (IP) Enterprise Communications Solution
designed to meet the telecommunication needs of the large sized business. iPECS UCM uses advanced
packet voice and IP switching technology, which is combined with a rich feature content, to set a new standard
in Voice over IP (VoIP) systems.
The iPECS UCM consists of a family of intelligent Gateway Modules, media gateway cabinets and Call Server,
which are interconnected over Ethernet LAN, easing the installation process. A variety of Gateway Modules
are available including analog and digital network access gateways, which connect to the Public Switched
Telephone Network (PSTN), Integrated Services Digital Network (ISDN) or public and private VoIP networks.
The Gateway Modules, which make up the iPECS UCM, can be installed in a Media Gateway Cabinet (1U or
7U type). The cabinet can be on floor or 19” rack, as best fits the user needs and equipment room.
The iPECS UCM supports a variety of Phones; LIP phones, standard VoIP phones (SIP), WLAN Phone,
analogue SLT and various of soft clients including Phontage, UCS client and Mobile Client. With the LIP
Phones, commonly used features are activated by selection of a single button. Additionally, most functions can
be accessed from any telephone by dialing specific codes. For LIP users, these “dial codes” may be assigned
to Flexible buttons for easy access. In addition to the LIP Phones, optional LIP DSS Consoles are available to
expand the number of Flexible buttons available to the user.
The iPECS UCM provides an environment rich in features beyond today’s traditional circuit switched
telephone systems. In addition to a fully featured voice intercom, iPECS UCM incorporates basic Auto
Attendant/Voice Mail, Least Cost Routing, Automatic Call Distribution, and VoIP network interface, as well as
Web Management System. iPECS UCM incorporates an interface to the iPECS UCM Applications Service
Provider, a TAPI 3.1 TSP/MSP, TR-87, SNMP, CSTA and Ericsson-LG Enterprise propriety interface (UCTI,
SAPP). Unified Communications Services (UCS), iPECS Attendant is supported through optional application
software providing enhanced communications and presence. An optional Network Management Server (UCM-
NMS) software package is available allowing monitoring and management of environments.
The reliability, extensive feature content, the ability to support present and future applications with iPECS
UCM Call Server and the capability to use an array of Gateway Modules and instruments, permit iPECS UCM
to be tailored to meet the short and long term needs of the most demanding customer requirements.
