●vCAPI for client PCs including fax services and CTI,
●SNMP (e.g. statistics and error signaling),
●Routing via the xDSL network (for HXGS with 2nd LAN interface only).
Interfaces:
●10/100BT Autosense Ethernet twisted-pair,
●10BT Ethernet (for HXGS with 2nd LAN interface only) configurable with PPPoE,
●Up to 16 B channels,
●SLIP access (serial line interface) for initial startup, incl. cable (reference no. 
S30122-X5468-X3).
1.1.1 Prerequisite
For this application, TCP/IP is implemented as the transport protocol and Win95/98/
NT 4.0 or Windows 2000 as the client operating system. For the routing functionality, 
the IP/IPX protocols are transferred transparently, independent of the operating sys-
tem. Call numbers are allocated in HiPath HG 1500 via TCP/IP Address > Call Num-
ber (max. 100 call numbers for vCAPI and max. 48 stations for voice applications). 
The assignment of several call numbers to one TCP/IP address may be necessary if 
several services are to be configured (voice, fax, file transfer, etc.).
1.2 Short description
HiPath HG 1500 is an expansion card for Hicom 150 E Office/Hicom 150 H Point/
Com/Pro. It is used to connect a local LAN to Hicom systems and to link external 
LANs via the system’s ISDN interface. Telematics and CTI functions are also support-
ed. 
The connection to the local LAN is set up via an Ethernet twisted-pair interface 
(RJ45 connector); see Figure 2-1
 and Figure 2-4.
In the case of OfficePoint and Com, the connection to the system is set up via a 50-
pin edge connector of an expansion slot. The connection to the LAN is set up via an 
RJ45 connector on the HiPath HG 1500 board. 
In the case of OfficePro, the board is connected to the system via the backplane. An 
adapter for the backplane (part number C39228-A7195-A10, US backplane: C39195-
Z7404-A10) is used to connect the LAN with an RJ45 connector. 
V.24 interface
For loading and administration purposes (SLIP access), each system is provided with 
an individual V.24 interface (cable reference no. S30122-X5468-X3). In both sys-
tems, the V.24 connector for SLIP access is located on the board.

1.3 Service information
The unique worldwide Ethernet address (MAC address) is a factory default and can-
not be modified.
Card recognition is performed automatically in Hicom 150 E Office/Hicom 150 H, 
Point/Com/Pro. HiPath HG 1500 is installed as an individual board type in Hicom 150 
E Office/Hicom 150 H, Point/Com/Pro. 
The following items can be administered in Hicom:
●S0 station
●Xpress clients
●IP network lines
●numbering scheme
●associated dialing
●answer group (PC telephone)
●call forwarding (PC to fax)
●suppression of incoming 0
●CSTA interface
Details on the initial startup and on accessing the board can be found in the HiPath 
HG 1500 Administration Manual.
A separate tool (Assistant Xpress @LAN/HG 1500) that can also be used by the cus-
tomer or the LAN administrator is provided for entering and modifying data, e.g. the 
IP address of the customer LAN or ISDN numbers assigned to a communication part-
ner. The data is permanently stored in HiPath HG 1500. HiPath HG 1500 Assistant 
also facilitates the storage of a corresponding configuration file. This can then be re-
trieved if a board needs replacing. The tool also provides a facility for querying the 
software version. Access to HiPath HG 1500 administration is password-protected. 
This password can be changed; however, the Hicom password concept applies; see 
Ta b l e 1 - 1
.
Note that only the user and Hicom passwords are allowed.
A simple functional test can be performed directly at the customer PC or on a service 
PC with a network card, vCAPI driver and a CAPI-based application.
APS transfer for the HiPath HG 1500 board is usually performed via the LAN using 
the Assistant or, in exceptional circumstances, via the V.24 interface using the Load-
er.
Cable with reference number S30122-X5468-X3 (see also Section 2.1.1.1
 or 
Section 2.1.2.1
) is used for the V.24 port of the HiPath HG 1500 board.

1.5 Functional environment of HiPath HG 1500
1.5.1 Parallel operation
Hicom 150 E Office/Hicom 150 HCom/Pro systems support parallel operation of sev-
eral HiPath HG 1500 boards. 
1.5.2 Interworking with features 
1.5.2.1 Least Cost Routing (LCR)
In Hicom systems, LCR technology enables the most cost-effective connections via 
ISDN.
1.5.2.2 Trunk access/toll restriction
Trunk access is configured in Hicom 150 H/HiPath HG 1500Point/Com/Pro for call 
numbers used by Hicom 150 E Office. Hicom toll restriction for outgoing seizure is 
performed based on this trunk access in the same way as for outgoing calls.
1.5.3 Gatekeeper
The following functions are performed by a gatekeeper in an H.323 network:
●Registering H.323 end units,
●Managing rights and services,
●Converting station numbers to logical names or IP addresses and vice versa,
●Managing bandwidth on the network side,
●Registering gateways,
●Registering multiconference units,
●Can be linked to neighboring gatekeepers (zones).
The setup procedure for gatekeeper operations is described in Section 3.1.3
. System type  Number of boards

>
If no gateways or multiconference units are being used, IP telephony can also be 
implemented in H.323 networks without gatekeepers. Note, however, that the con-
nection can only be set up via the IP address in this case, so no authorizations and 
bandwidth control are possible.
In general, the following applies: without gatekeepers, many features may be dis-
abled or subject to severe restrictions.

2.1 HiPath HG 1500 boards 
HG 1500 supports two function groups: the “voice functionality” with the features 
H.323 GW and TFA and the “data functionality” with the features VCAPI and RAS. A 
board variant (X100) that only supports the data functionality (Data only) is available; 
this board is not equipped with signal processors and the associated logic.

The cable is connected to the HiPath HG 1500 HXGS/HXGS2 (OfficeCom and Offi-
cePoint) via the 8-pin Western socket (X3) located on the MDF side of the circuit 
board, see Figure 2-1
, or X3 and X4, see Figure 2-2.
Notes
Direct Ethernet twisted-pair connection to HiPath HG 1500 
The RJ45 cable must be crossed as follows:
A ferrite kit must be installed on the LAN 1 and LAN 2 lines on the RJ45 cable.
2.1.1.1 HXGS V.24 interface 
The Serial Interface Cable (SIC, S30122-K5468-X3-*) can be connected via a 6-pin 
MiniDin socket on the front panel of the HXGS. The SIC performs level conversion 
from TTL signals (HXGS) to V.24 (9-pin Sub-D socket). Depending on the SIC, the 
maximum authorized transmission rate for the V.24 interface is 19.2 kBit/s. Asynchro-
nous transmission only is supported.
The interface is used for administration purposes. It can be used for software updates 
or board configuration. It can also be used for software debugging. Table 2-3 Contact assignment of the HXGS LAN interfaces
