Preliminary Information

Hardware

Figure 1 depicts the functional block diagram of the
MEB90812 evaluation board. The hardware is a
single board computer with the embedded software
and the following hardware features:
·

One central office trunk interface (COIC)

Two analog line interfaces (SLIC) for analog
telephone sets (POTS)

Four digital line interfaces (DNIC) for digital
sets

One HDLC protocol controller

Three DTMF receivers

One RS-232 port, a 68302 processor, and
memory for communications between a
personal computer and on board devices

One RS-422 port and an H-MVIP header

The MEB90812 evaluation board can be partitioned
into three sections: IDX, peripherals, and the
microprocessor and its peripherals. The evaluation
board provides a platform for the user to examine
and exercise the features of the IDX with peripherals
such as analog sets, digital sets, central office, and
an HDLC controller. The IDX provides the digital
cross point switching between the peripherals on the
local ST-BUS streams with a data rate at 2.048 Mb/s.
The IDX also provides the integration of several
telephony functions that are required in a digital key
telephone system.

The microprocessor on the board performs the tasks
of communications between a personal computer
and the on-board devices. System expansion with
additional MEB90812 boards is easily achieved by
cascading up to four boards via the H-MVIP header.
With an expanded system, data and voice channels
can be transferred from one evaluation board to
another over the H-MVIP bus at a rate of 2.048,
4.096, or 8.192 Mb/s with the switching capability of
the IDX on each evaluation board. A single personal
computer can be used to control the devices on all
four boards.

Software

Operation of the evaluation board is performed via a
graphically intuitive user interface (windows console)
with the following features:
·

Monitor window to examine the content of any
registers and memory locations of the IDX as
well as other devices on the board at a specific
time interval

Various windows to examine and view the IDX's
telephony functions. The related windows are
as follows:

Connections

Conferences

Timing

Tone Generation

DBRT Receive

DBRT Transmit

Energy Detect

FSK Transmitter and Ringer

Pre-defined Tests

Macro editor

POTS and Central Office

Primitive level configuration allows access to the
various board device registers. Functional level
configuration allows the setting up of connections
and combines primitive-level register settings to
demonstrate a function. The console also facilitates
such housekeeping chores as communications setup
and macro editing. The Pre-defined Tests windows
provide test configurations to exercise the
functionality of the IDX and other devices on the
evaluation board.
