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.
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
tion.
For information on how to calculate the number of boards required for HG 1500, see Section
