Figure 7
Basic Connections to a Digital Switching System
Figure 7 shows the PEx 2045 in its different applications in a digital switching system. It is used
here as the main device in the switching network (SN), as a group switch (GS) to connect different
digital or analog subscriber line modules (SLMA, SLMD) or digital interface units (DIU) with one
another and as the interface device for the digital interface units. The SLICs and SICOFIs (PEB
2060) are subscriber line drivers and codec-filter devices, respectively, for the analog line. SBC
(PEB 2080), IEC (PEB 2090), IBC (PEB 2095) and ICC (PEB 2070) are the layer-1 and layer-2
ISDN devices for the digital line. The peripheral board controller PBC (PEB 2050) multiplexes the
different lines in a subscriber line module to the 2- or 4-Mbit/s highways, which are input to the group
switch.
