Description of Functional Blocks
3.7.1
IOM-2 Handler
The IOM-2 handler offers a great flexibility for handling the data transfer between the
different functional units of the ISAC-SX TE and voice/data devices connected to the
IOM-2 interface. Additionally it provides a microcontroller access to all timeslots of the
IOM-2 interface via the four controller data access registers (CDA).
Figure 37
shows the
architecture of the IOM-2 handler. For illustrating the functional description it contains all
configuration and control registers of the IOM-2 handler. A detailed register description
can be found in
Chapter
4.3.
The PCM data of the functional units
• Transceiver (TR) and the
• Controller data access (CDA)
can be configured by programming the timeslot and data port selection registers (TSDP).
With the TSS bits (Timeslot Selection) the PCM data of the functional units can be
assigned to each of the 12 PCM timeslots of the IOM-2 frame. With the DPS bit (Data
Port Selection) the output of each functional unit is assigned to DU or DD respectively.
The input is assigned vice versa. With the data control registers (xxx_CR) the access to
the data of the functional units can be controlled by setting the corresponding control bits
(EN, SWAP).
The IOM-2 handler also provides access to the
• MONITOR channel (MON)
• C/I channels (C/I0,C/I1)
• TIC bus (TIC) and
• HDLC control
The access to these channels is controlled by the registers MON_CR and DCI_CR.
The IOM-2 interface with the Serial Data Strobe SDS is controlled by the control registers
IOM_CR, SDS_CR.
The reset configuration of the ISAC-SX TE IOM-2 handler corresponds to the defined
frame structure and data ports of a master device in IOM-2 terminal mode (see
Figure
36).
