Technical Information:
UTIL200 can be placed in the card slot, which has been specially designed for it within the
rack. The module is connected to the appropriate 64-pin connector on BPL200-MAIN or
BPL200-AUX and then it is fixed to the front lower and upper parts on the metal rack through
the fixing latches on the front card cover.
There is a DSP module on UTIL200 that carries out the entire tone generation and receiving
operations. UTIL200 has the TDM/PCM switching circuits that maintain the entire inter-rack
switching. Moreover, intra-rack switching is also carried out by the UTIL200 module of each
individual rack in coordination with the CPU200 control.
In each UTIL200 module, there are 16 PCM channels for inter-rack switching and 14 PCM
channels for intra-rack switching. By this way, a two-rack system operates completely without
blocking. In addition to that, sufficient resources are available in each UTIL200 Module for
the operation channels listed below:
Number of DTMF receivers: 32
Number of DTMF generators: 8
Number of R1 receivers: 32
Number of R1 generators: 16
Number of Tone receivers: 12
Number of Tone generators: 12
Resources of the entire UTIL200 cards, which have been listed above are combined in a
common pool in systems with several racks, and by this way, the entire resources become
available to the entire system in general.
The UTIL200 card also includes a special switching circuit for the conferencing feature,
which is supported for up to 32 participants. Thanks to this circuit, several multiple
conferences with 32 participants in total can be carried out, as well as a single conference
with 32 participants. Likewise, in addition to the multiple conferencing feature, resources for
8 conferences with 3 participants are also available on the UTIL200 card.

UTIL200 MUST NOT BE REMOVED WHILE THE SYSTEM IS OPERATING.
Operational Information:
There are two LEDs on the front panel of the UTIL200 module. The upper one signifies that
the card is operating and the lower one displays the status of communication with the CPU.
During normal operation, the first LED lights continuously, whereas the other blinks.
Dimensions of UTIL200 are 20 cm. x 22.5 cm., and it weighs 0.3 kg.
VI.2. DS200S & DS200M
The UTIL200 card is not used in the DS200S and DS200M systems. The functions of that
card are fulfilled by circuits, which are present on the CPU200S card and with the switching
facility, the system allows a three party conference as well.
