1. Introduction
This Part B of the Technical Specifications concerns the UHF communications equipment to
be supplied, installed, and commissioned as part of this Project.
The UHF communications equipment shall constitute a multi-celled Multiple Address Radio
System (MARS) operating in the 450 MHz band. The MARS communications system shall be
fully integrated with the Authority’s optical fiber backbone communications system and
associated leased line facilities to enable the five existing Distribution Management System
(DMS) master stations to monitor and control relevant power apparatus on the Authority’s
medium voltage (MV) power distribution network.
The optical fiber backbone (OFB) system is based on Synchronous Digital Hierarchical (SDH)
technology, providing point-to-point communications via STM-16 core channels and STM4/1 access channels operating over Optical Line Termination Equipment (OLTE) and ITU
G.655 and G.652 ADSS optical fiber cable. The primary multiplexing capacity is up to 252 E1
or 7,560 E0 channels.
1.1 Scope of Work
The scope of work is based on a provisional UHF communications system design
dependent on radio cells consisting of MARS master radios and remote radios only. In this
respect, the Contractor shall supply, install, and commission a fully operational UHF
communications network consisting of the quantities of MARS radio cells specified in these
Technical Specifications. Each cell shall consist of a master radio and several remote radios
supporting data communications between new Feeder Remote Terminal Units (FRTUs) and
the existing DMS master stations.
The FRTUs, located at pole-top sites, are those that will serve as the DMS interfaces to
Remote Controlled Switches (RCSs). The MARS remote radios shall be co-located with the
FRTUs, whereas the corresponding master radios shall be located in substations and
electric offices served by the Authority’s OFB system or the Authority-provided leased line
Digital Data Network (DDN) services. MARS remote radios shall communicate with new MARS
master radios or existing MARS master depend on the coverage area and signal strength
level of MARS master. So that, new MARS radios shall be compatible with existing MARS
radios, ie. payload data and MARS diagnostic data can transfered between new MARS radios
and existing MARS radios without misinterpretation. The Contractor shall integrate the

Provincial Electricity Authority
existing MARS radios and new MARS radios radios on the best performance of all MARS
radios.
Considering the OFB system, the Authority will dedicate an E1 data channel to support
communications between each existing DMS and its OFB equipped substations and electric
offices. This will include the necessary drop and insert equipment and the communication
ports to which the corresponding ports of the MARS master radios shall be connected in
order to access the OFB system. For each MARS master radio, two sub-rate 9600 bps
channels will be supported, one for data traffic and one for diagnostic traffic.
Considering the sites to be served by the anticipated E0 leased line data channels available
from DDN service providers, the multiplexers needed to establish the same sub-rate
channel speeds as at OFB sites shall be provided by the Authority.
A block diagram illustrating the basic concepts of the MARS communications system is
presented in Appendix A. Furthermore, a conceptual representation of the required data
and diagnostic communication ports are illustrated in Appendix B.
Thus, within the context above, the Contractor’s scope of work as a minimum shall include
the supply, installation, and commissioning of the following UHF communications
equipment:
1) Remote Radios – The remote radios shall be co-located with FRTUs.
2) Modems – The radios shall include internal modems capable of meeting all
necessary interface requirements.
3) Enclosures – The MARS master radios shall be installed in Contractorprovided enclosures, whereas the remote radios shall be installed in the
pole-top enclosures provided by others.
4) Power Supplies –Each Remote radios shall include a Contractor supplied dcdc converter 12Vdc power supply operated from the 24 Vdc power sources
in the pole-top enclosures provided by others.
5) Other Items – All necessary antennas, cables, connectors, surge protection
devices, and installation accessories (such as cable ladders, conduits, etc.)
shall be provided to meet the full functional requirements and intent of the
MARS communications system. This shall include provision of the required
radio diagnostics software.

6.2.2.4 Diagnostic Provisions
The remote diagnostic capabilities shall be provided for the MARS master diagnostic
microprocessor to obtain data on the remote radio output power, received signal
strength, radio dc supply voltage and, if supported, frequency offset, FM deviation levels,
internal regulated voltage value, and voltage controlled oscillator (VCO) lock voltage.
Each MARS remote radio shall include an internal microprocessor used as a diagnostics
controller so that PC shall be capable of addressing the controller through a separate RS232 diagnostic communications port on the remote radio. In particular, frequency,
transmit power of one or more remote radios shall be adjustable from the master radio.
The diagnostic data transmitted over the RF channel shall use a digital encoding
technique or a data frame structure with separated diagnostic data field and diagnostic
filter-out features provided in the radios to ensure robust communications and eliminate
the possibility of diagnostic information being misinterpreted, for example, as real-time
data being sent to the DMS.
The PC shall be able to monitor the following parameters and diagnostics data, where the
"*" denotes values that shall be user adjustable via the connected PC. It is unacceptable
to require an external adapter to interface to the radio with the PC.
 Radio Parameters
– *Transmit and receive frequencies
– *Transmit Time-out timer setting
– *Soft carrier de-key setting (for RTS key)
– *CTS delay(for RTS key)
– Hardware/software revision level
– Serial no./model no.
 Radio Diagnostics
– *Transmit power
– *Frequency
– *Received signal strength
– Regulator voltage (if supported)
– Power supply voltage

6.2.2.5 Communication Modems
The radios shall have an internal modem and digital interfaces for a communications data
rate of 9600 bps. Digital interface techniques are required for the 9600 bps modem to
ensure that the bit error rate does not exceed 1x10-6 at -107 dBm operating in a 12.5 kHz
channel. The modem shall be asynchronous with an RS-232 direct interface. The "request
to send", "clear to send" turnaround time shall not exceed 15 milliseconds.
6.2.2.6 Remote Radio Directional Antenna
These units shall be directional unit suitable for a frequency range of 450-480 MHz and a

potential for lightning protection. Maximum power input shall be 100 watts. The front-toback ratio shall be 20 dB minimum. The connector shall be Type N, female. The
Contractor shall mount the antennas on a 5.08 cm pipe, 1.22 m long, attached to the
remote site structure pipe if at the top of the concrete pole for maximum path gain
(obstructed or long paths), or mounted on the side of the concrete pole, over the top of
the FRTU cabinet, with waterproof seals for applicable paths (line-of-sight or short paths
with minimum obstructions). The antenna mounting shall be adjustable so that the
antenna vertical and horizontal directions can be set in such a way as to compensate for
tilted concrete poles where necessary. High gain, such as 14 dBi (12 dBd) gain or greater,
directional antennas, mounted at the top of the concrete pole (with adequate clearance
from the power line) may be used on severely obstructed paths or, on very severe paths.
Also refer to Appendix D.
Installation shall be in accordance with details provided in Contractor supplied drawings.
6.2.2.7 Transmission Cable
A "superflexible" Heliax transmission cable of at least 1m in length shall be provided at
the remote radio’s antenna port. This cable along with the radio shall be installed within
the enclosure provided by others. It shall connect the radio’s antenna port to the
Contractor provided lightning protection device, which shall be equivalent to Polyphaser

transmission cable consisting of ½ inch low-loss Heliax foam-dielectric type or equivalent
shall be connected to the lightning protection equipment in order to complete the
radio’s connection to its Contractor supplied and installed antenna outside the enclosure.
This coaxial cable at least 3 m and up to 15 m in length shall be suitable for direct
environmental exposure. "O" ring seals shall be used on connectors, all of which shall be
