Terminal Mode
In TE mode the IOM-2 interface has the 12-byte frame structure consisting of channels
0, 1 and 2 (see figure 53):
– DD carries the 2B+D channels from the S/T interface, and the MONITOR 0 and C/I 0
– DU carries the 2B+D channels towards the S/T interface, and the MONITOR 0 and
Channel 1 of the IOM-2 interface is used for internal communication in terminal
applications. The IPAC is operated as a master device and communicates with slave
devices via MONITOR 1 and C/I 1 channels:
– DD carries the MONITOR 1 and C/I 1 channels as output to peripheral devices (e.g.
– DD carries the IC channels as output to other devices, if programmed (C C1 – 0 = 01
Bit 5 of the last byte in channel 2 on DD is used to indicate the S bus state (Stop/Go bit).
If required (cf. DIM2-0, MODED register), the S/G bit is evaluated for D-channel access
handling and bits 2 to 5 of the last byte on DU (BAC and TAD) are used for TIC bus
access arbitration (see chapter 2.7.6).
Figure 56 shows the connection in a multifunctional terminal with the IPAC as a master
and an external device (e.g. ICC PEB 2070) as a slave device.
