HiPath 3000/5000 in the LAN Network For internal use only
HG 1500 V3.0
● HXGM: Up to eight boards can be installed in an HiPath 3700/3750. With two PDM1 expansion
modules, each HXGM offers up to 32 IP channels for voice connections (Voice
over IP).
● HXGS (wall housing) or HXGR (19" housing): Up to four boards can be installed in HiPath
3500/3550 and up to two in HiPath 3300/3350. Both boards can process up to 16 IP channels
for voice connections with a single PDM1 expansion module.
The IP networked systems and the HG 1500 V3.0 boards are administered with two different
tools:
● HiPath 3000 Manager E: Extending the existing HiPath 3000 customer database to include
information for IP networking.
● HG 1500 V3.0 WBM: Performing HG 1500 V3.0 board settings.
> The IP address used for IP networking is always that of the first LAN interface. If IP
networking is routed via another interface, such as LAN2, use IP routing entries to
ensure that the LAN1 interface can be reached.
4.5.4.1 General Parameters for Voice over IP
Before configuring system clients and H.323 clients, you must configure the valid parameters
for both variants in HiPath 3000 Manager E:
● Echo:
You can define here how to compensate for the echoes that occur in connections to conventional
telephones via the voice gateway.
● Traffic statistics:
This is where you define whether to record traffic statistics which can then be queried via
SNMP.
● Encoding:
This parameter is used to select which voice coding will be implemented.
4.5.4.2 Voice Coding
HiPath 3000/5000 supports voice compression according to the G.729 and G723.1 standards.
G.723.1 facilitates the use of teleworking via ISDN for example, and reduces the load on the
existing data network. G.723.1 reduces the VoIP bandwidth requirement for voice communication.
This enables a bidirectional voice connection via an ISDN B channel. This, in turn, facilitates
the connection of teleworkstations or branch offices to the company network via a 64 KB
connection. However, it is not advisable to operate other applications (such as Application
Sharing, File Transfer) in addition to a bidirectional VoIP connection simultaneously via 64 Kbps
since this generally leads to a deterioration in voice quality. It is recommended that both B channels
of an S0 connection are used for this purpose.
