STMI2
Introduction
STMI2 (Subscriber Trunk Module IP) is a VoIP gateway board (VoIP - Voice over IP) which pro-
vides the functionality of HG 1500 in HiPath 3800. This includes:
●
Connection of a local LAN to the HiPath 3800 and connection with external LANs via the
ISDN and DSL interfaces of HiPath 3800.
●
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).
●
Bidirectional video signal transmission on the SIP interface (OpenScape Personal Edition).
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
2.5.
Board versions
Sixteen simultaneous Voice over IP connections are possible per DSP (Digital Signal Proces-
sor).
>
A combination of up to eight STMI2 boards can be used per system, but the following
restrictions must be observed:
●
A maximum of four STMI2 boards may be inserted per HiPath 3800 cabinet.
●
To allow for future channel expansion with extension modules, the slot between
two STMI2 boards should remain free.
Information on configuration is provided in the
HG 1500 administrator documenta-
tion
