Introduction
2Introduction
2.1 General
This document describes the architecture and functions of the SUPM1 unit
and shows, how this unit is commissioned and operated as part of the
XMC20.
The SUPM1 unit is a 1-slot wide service unit of XMC20. It has 16 PSTN user
ports with a telephony bandwidth of 300 Hz to 3.4 kHz. The SUPM1 unit con-
verts the analogue voice signal to a 64 kbit/s digital signal (and vice versa).
This type of user ports is also called FXS interface, 2-wire analogue interface
or a/b-interface.
The SUPM1 unit allows the connection of an analogue telephone set to a
local exchange via a TDM network.
Another application is in a private network where two telephone sets are
directly interconnected without a local exchange.
Figure 1: SUPM1 applications with and without local exchange
The SUPM1 unit is connected to a P12 transport unit, e.g. SELI8, via the
PBUS in the backplane of XMC20.
The SUPM1 unit can also be connected to the Voice over IP (VoIP) media
gateway VOIP1 via the PBUS in the backplane of XMC20.
Where the voice circuits are running in environments with high electrical
interference, e.g. near the rail infrastructure, the high voltage common mode
filter box FIL16 can be deployed between the SUPM1 front ports and the
line. For more information please refer to [458] User Manual “FIL16”.
