1. System Introduction
1.1 System Overview
Integrated Platform
The eircom advantage 4800 system integrates all of the needs of a small business into a
single platform that includes Internet access, voice, data and voicemail. Voice calls are
handled with the full functionality of a traditional PBX. Calls can be made, received, placed on
hold and transferred from any extension on the system to any internal or external party.
Capacity
The basic control unit is equipped for 16 extensions - 8 digital and 8 analogue. The capacity
of the system can be expanded up to 48 extensions by the addition of extension modules into
the 2 extension slots. There are no line interfaces on the basic control unit - these are also
added by slotting either PSTN or ISDN line modules into the two line expansion slots to a
maximum of 8 BRA, 8 PSTN or a combination of both. A 30B+D ISDN Primary rate access
(PRA) module can also be connected to the line expansion slots, thereby substantially
increasing the line capacities.
The data connectivity of the system is comprised of an integrated ISDN router with data call
management and an ADSL modem module that provides broadband Internet access. Both
the integrated ISDN and optional ADSL routers contain firewall protection for security
purposes.
