HXGS3, HXGR3 
 

Introduction  
HXGS3 and HXGR3 are VoIP gateway boards (VoIP - Voice over IP) that provide the functionality of HG 1500 in HiPath 3550, HiPath 3350 (HXGS3), HiPath 3500, and HiPath 3300 (HXGR3):
 •   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 functionality 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).
 •   Bidirectional video signal transmission on the SIP interface (OpenScape Personal Edition).
Configuration is performed via Web-Based Management (WBM) which enables the administration of HG 1500 without any special software requirements.
For information on how to calculate the number of boards required for HG 1500, see Section 2.5 "Dynamic Configuration Rules".

HXGS3/HXGR3 Installation  
Up to three boards can be used in HiPath 3550 and HiPath 3500.  
A maximum of one board is permitted in HiPath 3350 and HiPath 3300. Two boards can be installed only if PDM1 is not being used.  
When using an HXGS3 in HiPath 3350, pthe ower supply unit PSUP must be replaced with UPSC-D.  
It is not possible to operate an HXGS3 or HXGR3 and an LIM module simultaneously in one system.  
For information on configuration, refer to the HG1500  Administration Manual.

Upgrade, fan kit  
If the following housing covers are avaiable on the HiPath 3350 and HiPath 3550 systems, a fan kit is not required when upgrading with a HXGS3:
 •   HiPath 3350: from housing cover C39165-A7021-B53
 •   HiPath 3550: from housing cover C39165-A7021-B52
If the HiPath 3350 and HiPath 3550 systems have the old housing covers and should be upgraded with a HXGS3, then the old housing covers must be replaced by C39165-A7021-B53 or C39165-A7021-B52 housing covers.

Eight simultaneous Voice over IP connections are possible per DSP (Digital Signal Processor).
When using the extension module PDM1, the number of DSP channels for HXGS3 and HXGR3 boards can be expanded by eight per board.  

Extension modules  
The HXGS3 and HXGR3 boards each have two HGA (HiPath Gateway Accelerator) slots, which can be used to connect extension modules.

Interfaces/connectors  
The HXGS3 and HXGR3 boards provide the following connectors:
 •   X1: 50-pin connector (edge connector) to the system
 •   X2: 8-pin RJ45 jack for LAN interface 1
 •   X3: 8-pin RJ45 jack for LAN interface 2
   
Caution  
It is absolutely necessary to use a shielded Ethernet cable for LAN interfaces/ports of the HXGS3 board.  
    Both LAN interfaces allow access to the Ethernet standard (IEEE 802.3) with 10 Mbps or 100 Mbps with automatic configuration. Manual configuration is also possible.
 •   X4: 9-pin Sub-D plug for V.24 interface

Signals TT1/2 and RT1/2 are not needed for transmitting data. They represent a signal termination of 100 ohms (known as a Bob Smith termination) for the two unused wire pairs in a 4-pair twisted pair cable.  

V.24 interface  
The V.24 cable (C30267-Z355-A25) is used for connecting the service PC.
The following settings must be chosen for a terminal or PC connected to the V.24 interface:
Transmission rate  
19.200

Parity bit  
None  
Stop bits

It is recommended that the local echo be deactivated on the connected terminal or PC.
