Introduction
PT/PR-150C Module Installation & Operation Manual Harris Corporation
Issue 1, October 2000 Intraplex Products

1.1 Introduction
This manual describes the setup and installation procedures for the Intraplex
PT-150C and PR-150C Program Audio Modules. Experienced users may refer
directly to the tables in Section 2 for configuration data.
Additional information about this system is contained in your Intraplex
multiplexer operation manual.
The PT-150C transmitter module and PR-150C receiver module are designed for
use in Intraplex terminal and drop/insert multiplexers. The modules enable
transport of professional quality audio signals over T1, E1 (2Mbps), and other
digital communications facilities.
Each module has two separate channels, and performs A/D (transmit) or D/A
(receive) conversion on stereo or dual mono program signals of either 7.5kHz or
15kHz bandwidth. The apt-X digital signal compression enables transmission of
a 15kHz channel using only two 64kbps time slots.
User-adjustable switches and jumpers allow configuration of several parameters:
•Frequency bandwidth of program material
•Single or dual channel operation
•Audio input impedance
•Selectable apt-X Auto Sync mode
•Selectable J.17 emphasis/de-emphasis
•15- or 16-bit digital audio coding
•Selectable transmit and receive directions for use in drop and insert
multiplexers
•Time slot selection

SW7 sets the SCB Address for the PT-150C and PR-150C. The SCB Address is
used when the module is to be remotely controlled through the multiplexers
REMOTE port.
For remote access, each channel module in an Intraplex multiplexer must have a
unique card address. Valid addresses are the numbers 1 to 36. Determine the
physical slot number of the card and set SW7 according to the settings in
Table1-9.

2.1 Introduction
Refer to the figures and tables in Section1, About the PT-150C and PR-150C as
necessary during this procedure. Before changing the configuration of a
PT/PR-150C module, please review Section7, Application Considerations, for
recommended settings.
Power supply and time slot considerations may affect the installation of a channel
module into an existing multiplexer shelf. Refer to the sections on Channel
Module Configuration Rules and Adding Channel Modules to Existing Systems in
your multiplexer operation manual for more information.
2.2 Configuration
The switches on the PT-150C transmitter and its corresponding PR-150C receiver
must be configured identically for proper operation. The only exceptions are the
card address and REMOTE switches, which are independent for each card, and
the TERMINAL MODE switch, whose setting will depend on the layout of the
network.
Choose an unused physical slot in the Intraplex multiplexer for installation of this
module. Make sure that the appropriate module adapter is installed at the rear of
the slot (see Section6, Module Adapters for the PT/PR-150C).
1. Select the time slots using SW2 and SW4. If you are installing this card in an
E1 multiplexer, refer to Table 1-4 on page1-9. For other Intraplex
multiplexers, refer to Table 1-3 on page1-8.
2. Select an audio bandwidth with the 15KHZ switch (SW6, position1): up for
7.5kHz or down for 15kHz. Next, select one or two channel operation with
the CH2_ON switch (SW6, position2): up for one channel or down for two
channels. (See also Section1.6, Local Configuration Parameters, on
page1-10.)
3. Select J.17 pre-emphasis on or off with the EMP1 (left channel) and EMP2
(right channel) switches (SW5, positions 2 and 3): up for pre-emphasis off
and down for pre-emphasis on. (See also Section1.6, Local Configuration
Parameters, on page1-10.)
4. Select 15 or 16-bit operation for the left and right channels using the
CH1_BIT and CH2_BIT switches respectively (SW6, positions 3 and 4): up
for 16-bit or down for 15-bit. (See also Section1.6, Local Configuration
Parameters, on page1-10.)
5. Set Auto Sync on or off with the AUTO switch (SW5, position5): up for
Auto Sync off or down for Auto Sync on. (See also Section1.9,
Configuration Settings, on page1-12.)
6. Select the desired communication port using the TERM switch (SW6,
position6). In a terminal multiplexer, this switch must be down. In a
drop/insert multiplexer, set the switch up to communicate through the DI-B
port, or down to communicate through the DI-A port (see Section5.3.4, Drop
and Insert Operation, on page5-8).
