SECTION INTRODUCTION
This section gives the location and describes strapping, power connections, signal connections, status and alarm connections, and service channel connections. For further details,
refer to the complete instruction book on the attached CD ROM.
3.1
INSTALL POWER CABLE ASSEMBLIES
See Figure 3-1 for power cable assembly installation procedures. The MDR-8000 is internally
wired to accept 20.5 to 60 V dc input power with positive or negative ground. To protect maintenance personnel from lightning strikes, the ground system must be integrated by bonding
station ground and dc battery return together. The dc power connectors J1 and J2 are located
on the rear of the back panel. Install power cables as shown.
3.2
DANGER
Possibility of
Injury
to Personnel
Short circuiting low-voltage, low-impedance dc circuits can
cause arcing that may result in burns or eye injury. Remove
rings, watches, and other metal jewelry while working with
primary circuits. Exercise caution to avoid shorting input
power terminals.
DANGER
Possibility of
Injury
to Personnel
To protect maintenance personnel from antenna tower lightning strikes, the ground system must be integrated by bonding frame ground and dc battery return together.
WARNING
Possibility of
Damage
to Equipment
Do not apply battery power until it is determined that A and
B battery cables with isolated returns and power cables are
wired correctly. With power applied, reverse polarity on wiring (+batt wired to -batt pin on connector) can cause power
supply fuse to blow.

3.4 SHELF/RACK ALARM CONNECTION
Each MDR-8000 rack equipped with the Power Distribution Unit (PDU) 695-6200-001/002
has a visual rack alarm indicator to report a shelf failure. In order to activate a rack alarm
visual indicator on the PDU, the shelf alarm output from each MDR-8000 shelf must be
hardwired to connector J1 on the PDU. The shelf alarm is provided on alarm connector
J305 pin 24 (major/visual alarm). A wire-wrap adapter (PN 695-4171-002) for connector
J305 is available. Insulated 22-gauge solid copper wire is recommended for connecting to
the wire-wrap adapter. To attach to J1 (2-pin connector) on the PDU, use 2-position socket
housing PN 372-0114-140 and socket contact PN 372-0114-390. See Figure 3-3, sheet 1,
for shelf-to-rack alarm wiring.
Each MDR-8000 rack equipped with PDU 3EM13317AA has a blown fuse alarm visual
indicator and a Form C relay alarm output (J4, J5, and J6) for connection to customer
alarm equipment.
An optional Fuse and Shelf alarm plug-in assembly is available to provide shelf alarm connections requiring Form C relays. The alarm inputs (major and minor) must be hard wired to J3
on the PDU. The alarms are provided on alarm connector J305 pin 24 (major/visual alarm) and
pin 50 (minor/audible alarm) of each shelf. A wire-wrap adapter (PN 695-4171-002) for connector J305 is available. Insulated 22-gauge solid copper wire is recommended for connecting to
the wire-wrap adapter and also to J3 on the PDU. Alarm outputs are transmitted to customer
equipment via Form C relay outputs (J4, J5, J6, relays 1 through 8). This option also includes
the blown fuse alarm indicator and Form C relay alarm output (J4, J5, and J6 – relay 9). See
Figure 3-3, sheet 2, for shelf to PDU alarm wiring.

DS3 LBO WAYSIDE DS1 CONNECTIONS (J201 IN AND J202 OUT)
Wayside DS1 is an option in the MDR-8000 DS3 radios. This option provides 1 DS1 for
each equipped DS3. To activate the wayside channels requires a small circuit board, called
ELMC option key, that plugs onto the controller module. The protection of the wayside
channels follows the protection scheme of the radio configuration. In other words, if the
radio is hot-standby the wayside channels are hot-standby. The channels are point to point
just as is the payload traffic. They are independent of the traffic and reside in the overhead
channels. The advantage of the wayside DS1 is the ability to drop 1 to 3 DS1’s without having to add a 1:3 muldem to access the traffic. Refer to Table 3-4 for ELMC option key
requirements for remote monitoring/controlling wayside DS1s.

3.15 SERVICE CHANNEL
A service channel is defined as a non-revenue bearing channel provided as part of a transmission system for operation, maintenance, monitoring, and control of the system. The
MDR-8000 provides a 256 kb/s auxiliary channel for servicing the radio. This is an overhead channel and is independent of the traffic channels. The 256 kb/s service channel contains four 64 kb/s service channels. Three of the four 64 kb/s channels (Service Channel 1,
2, and 3) can be provisioned on the USI for a specific use. Service channel 0 is dedicated to
radio commands and ELMC. Service channel 0 is not provisionable. The four channels are
multiplexed and shifted in and out of registers on the controller.
3-22
See Figure 3-16. There are eight connectors on the backplane to interface with three of the
service channels. The connectors on the backplane interface three functions: audio, RS232, and MCS-11. Each service channel is provisioned for a specific function. As shown by
the vertical line connecting to the three functions on one side and the three service channels (SC1, SC2, and SC3) on the opposite side, audio and MCS can be put on any open service channel. RS-232 data can be put on service channel 1 or 2 but cannot be put on service
channel 3. This is shown by the dashed lines to the specific service channel.
3.15.1
Handset Jack
The 2-wire port at the TEL connector on AE-37Y Controller accepts either the optional
handset or a standard telephone. The 2-wire port is not provisionable. To use the handset,
the radio must be provisioned for Audio 1.

MCS-11 Connections
When MCS is selected to be placed on one of the three service channels and then RSS is
enabled and properly addressed, applicable ports on the controller module are enabled.
This allows the user to interface external MCS-11 Monitor and Control System equipment
at any or all four connectors on the backplane (J307, J308, J309, and J310). Two connectors (J308 and J309) are synchronous, parallel, data ports and provide CLK outputs. Connectors J307 and J310 are asynchronous ports.
For proper operation, MCS-11 must be provisioned using the following guidelines:
a. MCS-11 must be selected as one of the service channels.
b. MCS must be assigned a valid address
c. The MCS RSS must be set to ON for each radio with a unique RSS address. Refer to
Appendix B on the attached CD for address details. At a site, typically only one RSS is
turned on. Station scanners at all other radios at that site are normally jumpered to the
RSS enabled radio to allow access to their detail scanners. If station scanners are properly wired, detail scanners always respond, regardless of whether RSS is provisioned
ON or OFF.
3-28
Note
MCS-11 must be provisioned MCS-11 J310 Master/Junction to enable
XMT, RCV, and OUTPUT clocks. If an external modem is being used,
provision MCS-11 for MCS-11 J310 Modem. This selection disables
XMT, RCV, and OUTPUT clocks and all MCS-11 clocks must now be
provided by the external modem.
d. MCS-11 J310 Master/Junction must be selected unless an external modem is connected to the radio. If an external modem is used it must provide all MCS-11 clocks and
the radio must be provisioned MCS-11 J310 Modem.
Note
When provisioned J308 Input Clock, J308 and J309 RCV CLK and
XMT CLK and J308 OUTPUT CLK are disabled. Select J308 Output
Clock to send a 64 kb/s clock to external equipment (OUTPUT CLK
J308-4/12) and also enable RCV CLK and XMT CLK.
e. MCS-11 J308 Output Clock must be selected unless an external clock source is provided that will supply all MCS-11 clocks. If an external clock source is used, the radio
must be provisioned MCS-11 J308 Input Clock.
3.15.5.1
MCS-11 (J307)
Note
If the radio is provisioned Repeater, port 2 on the controller, that connects to J307, is disabled. At a repeater, you can use J310 in lieu of
J307 for connecting the TSM polling engine to the radio.
MCS-11 connector J307 is used to connect to a TSM (-2500, -3500, or -8000) polling engine
at a master terminal.
Recommended connectorized cable assembly – PN 695-4126-007/009/012 (26 AWG 8 pair
shielded, jacketed cable). See Figure 3-20 for shelf connector location and pinout. Refer to
Table 3-8 for mating cable pinout and color code. See Figure 3-21 for typical connection
scheme.

MCS-11 Repeater-to-Spur Daisy Chain Connection (J308/J309)
Note
MCS-11 must be provisioned MCS-11 J310 Master/Junction to enable
XMT, RCV, and OUTPUT clocks. If an external modem is being used,
provision MCS-11 for MCS-11 J310 Modem. This selection disables
XMT, RCV,OUTPUT clocks and all MCS-11 clocks must now be provided by the external modem.
Note
Multiple radios at a site can be provisioned and connected to operate
using a common XMT and RCV clock. In this scenario, one radio is
provisioned to supply the clocks. All other radios are provisioned to
sync off the supplied clocks. Provision the radio supplying the clocks
J308 Output Clock. Provision all other radios at the site J308 Input
Clock.
MCS-11 connector J308/J309 is typically used to connect a repeater to a spur or multiple
spurs in a daisy chain system configuration. Either repeater shelf 1 or repeater shelf 2 may
feed the spur shelf. The first connection out of the repeater must be crosswired from J308
to J308. Then, every shelf from the spur must be wired 1:1, J309 to J308, in a daisy-chain
fashion.

3.17 ALARM, STATUS, CONTROLS INTERCONNECT
See Figure 3-27 for interconnect diagram. The AE-27( ) Relay Interface provides alarm,
control and status inputs, and alarm, status and control relay outputs. All output relays
can be disabled or provisioned normally open or normally closed as follows:
Normally open (NO) – relays are normally de-energized and relay contacts are open. When
activated, relays are energized. Relay contacts close, connecting the output to ground.
Normally closed (NC) – relays are normally energized and relay contacts are closed and
grounded. When activated, relays are de-energized. Relay contacts open, presenting an
open (high impedance) to the output.
Rack ALM Return, Pin 49 is a ground point for use with Rack ALM Out. It is a signal
ground (low current) not used for battery voltage or high current ground.

3.17.1
Controller Bus
The Relay Interface communicates with the AE-37( ) Controller card via the processor bus
and the data bus. The processor bus, consisting of three address lines, two control lines,
and a clock, is applied to a XCVR. The data bus contains the eight data lines (D0-D7) and
is applied to a separate transceiver. Interface with the relay transceivers is provided by the
XCVR data bus. When commanded by the AE-37( ) Controller, the decoder/DEMUX
decodes and demultiplexes the address and enables the appropriate relay XCVR via the
EN2-9 controls. The controller can then write alarm/status/control information to the relay
XCVRs, or read alarm/status/control inputs from the relay XCVRs. Further descriptions of
the controller interface signals follow:
• Address lines A0 through A3 – HCMOS inputs. 100K Ohm pull-ups. Used by address
decoders to enable output registers and input buffers.
• Buffered bidirectional data lines D0 through D7 – HCMOS input/outputs. 10K Ohm
pull-ups. Used to write data to output registers and read present bits or data from
input buffers.
• ECLK – 2 MHz bus clock. HCMOS input. 100K Ohm pull-up.
• R/WF Read/Write False. HCMOS input. 100K Ohm pull-up. A logic 1 indicates data is
being read from an input buffer or the present bits. A logic 0 indicates data is being
written to an output register.
• Relay Intfc CSF – Relay Interface Card Select False. HCMOS input. 100K Ohm pull-up.
Chip select for relay interface card. Active low.
3.17.2
Control Inputs
Nine buffered control inputs are provided. The inputs are diode protected from voltages outside of the 0 to +5 V range, and have a 10K Ohm resistor for current limiting purposes. In
addition, each input has a 100K Ohm pull-up resistor.
• Switch Transmitter (SWITCH TX) – buffered HCMOS input, sends signal to controller
module to activate the transmitter that is currently not carrying traffic.
• Switch Receiver (Switch RX) – buffered HCMOS input, sends signal to controller module to activate the receiver that is currently not carrying traffic.
• Switch I/O Interface (SWITCH I/O) – buffered HCMOS input, sends signal to controller
module to activate the stand-by I/O interface module.
3.17.3
Station Alarm Inputs/TBOS Interface
Each radio shelf can accept/report up to 12 different user-defined station-type alarms, and, if
provisioned Station Alarm 13-16, the radio can accept an additional four station alarms, for a
total of 16. Station alarms 13 through 16 share pins on connector J305 with the four TBOS
inputs and outputs. TBOS inputs and outputs are enabled by software when the radio is provisioned TBOS Display 1-8. When TBOS is enabled station alarms 13 through 16 are disabled.
The alarm/status input signals are buffered HCMOS inputs, diode protected from voltages
outside of the 0 to +5 V range, with 10 kilohm current limiting (series) resistor and 100
kilohm pull-up resistor. A logic 0 indicates an alarm state. A logic 1 (or open) indicates a
non-alarm state.

Station Alarm Wiring
See Figure 3-28. Use wire wrap adapter PN 695-4171-002 to connect station alarm inputs
to the AE-27A Relay Interface module, via connector J305, in each rack. A typical connection scenario is shown. The station/shelf alarm for MCS-11 address A1A (MCS-11 alarm
point 1) is connected by software. The station alarms for MCS-11 address A1B and A1C are
assigned to MCS-11 Alarm points 2 and 3, respectively.

3.17.6
Relay Control Outputs
Note
Control outputs and control status inputs operate together to perform
control functions. The control status inputs to the relay interface must
be properly wired to the external equipment that is being controlled by
the associated control output in order to display the ON or OFF status
on the USI control screen. Without the control status inputs, the control
function on the USI screen will still turn on equipment/functions, but
no status will be indicated and, once turned on, the equipment/function cannot be turned off.
Six relay control outputs (CTRL 1-6) provide relay closure to ground (provisioned NC) or
open (provisioned NO) when activated. These relays default to open if card power is lost.
The maximum contact rating for each relay is 0.5 A, 100 Vdc.
Nine buffered status inputs (CTRL STATUS 1-6) from the equipment controlled by the
CTRL 1-6 outputs, verifying the controlled function. The inputs are diode protected from
voltages outside of the 0 to +5 V range, and have a 10K Ohm resistor for current limiting
purposes. In addition, each input has a 100K Ohm pull-up resistor.
