Section 7 contains pin descriptions of the MC145574. The pin descriptions differentiate between the
device configured for NT mode or TE mode of operation, and GCI and IDL2+SCP.
As mentioned previously, the MC145574 is used for the transmission of two 64 kbps B channels and
one 16 kbps D channel. Access to the B channels is determined by the network. The TEs gain access
to the D channel in accordance with CCITT I.430, ETSI ETS 300012, and ANSI T1.605 recommenda-
tions. A description of the D channel operation is contained in Section 11.
In addition to the 2B+D channels, the S/T transceiver has a multiframing capability. Multiframing is
a layer 1 signalling channel for use between the NT and the TE(s). The multiframing operation is de-
scribed in Section 12.
The MC145574 can be configured in several different operating modes depending on the application.
Section 13 describes all the possible configurations, whether in the NT or TE mode.
Section 16 describes how to interface the MC145574 to the S/T bus. Section 17 describes the various
power modes of operation. Section 18 contains electrical specifications, and Section 19 contains me-
chanical data relevant to the MC145574. Section 20 describes the differences between this data book
and the F57J4 mask version of the MC145574.
The features of the MC145574 are described below.
