IOM
In this case the IOM has the 12-byte frame structure consisting of channels 0, 1 and 2 (see
figure 11):
– IDP0 carries the 2B+D channels from the S/T interface, and the MONITOR 0 and C/I 0
– IDP1 carries the MONITOR 0 and C/I 0 channels to the layer-1.
Channel 1 of the IOM interface is used for internal communication in terminal applications. Two
cases have to be distinguished, according to whether the ISAC-S TE is operated as a master
device (communication with slave devices via MONITOR 1 and C/I 1), or as a slave device
(communication with one master via MONITOR 1 and C/I 1).
If IDC is set to "0" (master mode):
– IDP0 carries the MONITOR 1 and C/I 1 channels as output to peripheral (voice/data)
– IDP0 carries the IC channels as output to other devices, if programmed (C C1 – 0 = 01 in
If IDC is set to "1" (slave mode):
– IDP1 carries the MONITOR 1 and C/I 1 channels as output to a master device;
– IDP0 carries the IC channels as output to other devices, if programmed (C C1 – 0 = 01 in
If required (cf. DIM2-0, MODE register), bit 5 of the last byte in channel 2 on IDP0 is used to
indicate the S-bus state (stop/go bit) and bits 2 to 5 of the last byte are used for TIC-bus access
arbitration (see chapter 2.3.6).
Figure 12 shows the connection in a multifunctional terminal with the ISAC-S TE as a master
(figure 12b) and an ICC as a slave device.
