3.7.3.1
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 (MR) and MONITOR Channel
Transmit (MX) bits. Data is placed onto the MONITOR channel and the MX bit is
activated. This data will be transmitted once per 8-kHz frame until the transfer is
acknowledged via the MR bit.
The MONITOR channel protocol is described in the following section and
illustrates this. The relevant control and status bits for transmission and reception are
listed in

controlled from a master device on IOM-2 (e.g. ISAR34 PSB 7115). This is used in
applications where no microcontroller is connected directly to the ISAC-SX TE in order
to simplify host interface connection. The HDLC controlling is processed by the master
device therefore the HDLC data is transferred via IOM-2 interface directly to the
master device.
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 simplifies the
system design of terminal equipment.
