In IOM-2 mode, the MONITOR channel protocol is a handshake protocol used for high
speed information exchange between the IPAC and other devices in MONITOR channel
"0" or "1" (see figure 53). In the non-TE mode, only one MONITOR channel is available
("MONITOR channel 0").
The MONITOR channel protocol is necessary:
• For programming and controlling the layer-1 part of the IPAC over MONITOR
• For programming and controlling external devices attached to the IOM-2 interface
• For data exchange between two microcontroller systems attached to two different
Figure 62
The MONITOR channel operates on an asynchronous basis. While data transfers on the
bus take place synchronized to frame sync, the flow of data is controlled by a handshake
procedure using the MONITOR Channel Receive (MR0 or 1) and MONITOR Channel
Transmit (MX0 or 1) bits. For example: data is placed onto the MONITOR channel and
the MX bit is activated. This data will be transmitted repeatedly once per 8-kHz frame
until the transfer is acknowledged via the MR bit.
channel 0. The layer 1 registers are not directly accessible to the host for read and
write accesses via the common register set.
when the layer-1 part of the IPAC is disabled (CONF:TEM). Examples of such devices
are: layer-1 transceivers (using MONITOR channel 0), and peripheral V/D modules
(using MONITOR channel 1) that do not need a parallel microcontroller interface, such
as the Audio Ringing Codec Filter ARCOFI PSB 2163.
devices on one IOM-2 backplane. Use of the MONITOR channel avoids the necessity
of a dedicated serial communication path between the two systems. This greatly
simplifies the system design of terminal equipment (figure 62).
