Due to the IOM-2 interface the IEC-Q TE can be combined with a variety of other devices
to fit in numerous applications. This chapter only shows some typical applications of the
IEC-Q TE.
1.7.1
An ISDN adapter card which supports the U-interface may be realized using the
IEC-Q TE together with the PSB 2113 3PAC (figure 5). The 3PAC provides a D-channel
and two B-channel HDLC controllers. Optionally, a PSB 2132 SICOFI2-TE can be
connected to provide two POTS interfaces. If an S-interface is required, the PSB 2115
IPAC can be used instead of the 3PAC.
