3.3.3 HXGM3
Introduction
HXGM3 is a VoIP gateway board (VoIP - Voice over IP) which provides the functionality of
HG 1500 in HiPath 3750 and HiPath 3700:
● Connection of a local LAN to the HiPath 3000 and connection with external LANs via the
ISDN and DSL interfaces of HiPath 3000.
● Support for the conventional functions of an ISDN and DSL router with the additional func-
tionality of a media gateway for the transfer of voice, fax and data.
● Forwarding of calls between IP-supported networks (LAN, intranet, Internet) and circuit-
switched networks (ISDN, PSTN).
Configuration is performed via Web-based management (WBM) which enables the administra-
tion of HG 1500 without any special software requirements.
For information on how to calculate the number of boards required for HG 1500, see
Section 10.6.4.
Board versions
Eight simultaneous Voice over IP connections are possible per DSP (Digital Signal Processor).

A combination of up to eight HXGM3 boards can be used per system, but the follow-
ing restrictions must be observed:
● A maximum of four HXGM3 boards may be inserted per HiPath 3750 or HiPath
3700 cabinet.
● To allow for future channel expansion with extension modules, the slot between
two HXGM3 boards should remain free.
● It is not possible to operate an HXGM3 and an LIM module simultaneously in a
HiPath 3750 or HiPath 3700.
For information on configuration, refer to the HG 1500 Administration Manual.
