November 1999
M68333 Rev. A Tel-Link PMP - Sector Terminal Installation & Maintenance Manual 2-1
2.0 Sector Terminal Overview
The PMP network is composed of one or more base stations that are strategically located within the desired
coverage area (refer to Figure 2-1). Base Station/Sector Terminals are located at the center of each cell
and have a radius of up to 10 Km depending on the RF frequency, climate type, desired network availabil-
ity, line-of-sight profiles, and traffic capacity requirements. The Base Station consists of 1 to 24 Sectors. A
sectorized area of a Base Station/Sector Terminal is supported by 1 to 5 Sector Indoor Units (IDUs),
depending on the number of Remote Terminals located in that sector. Each Sector communicates directly
with the Remote Terminal within a sector area of 22.5° to 90° of coverage within the 360° area around the
base station. Each base station also interfaces to the Public Switched Network (PSN) through a high-speed
backbone link.
Figure 2-1 - Example of Simplified Base Station Site
The system utilizes an ATM cell-multiplexed, continuous carrier to transmit data from the base station to the
Remote Terminals. Each sector uses one or more downlink carriers to deliver these cells to the Remote
Terminals. These carriers are transmitted at different frequencies to avoid interference. Either a FDMA or
TDMA scheme is used by the Remote Terminals to transmit information to the Base Station. When FDMA
uplinks are used from the Remote Terminals, each Terminal communicates on a separate frequency chan-
nel with a demodulator at the Base Station for each channel. When TDMA uplinks are used from the
Remote Terminals, multiple remotes share a single carrier by transmitting in designated time slots.
November 1999

2.2 Sector ODU Power Supply
The Sector ODU Power Supply is a rack mounted unit supplying DC power to the ODUs and designed to
avoid single points of failure and ease of replacement of failed components. This unit is redundant utilizing
two power supplies within the chassis that load share and is fan cooled (refer to Figure 2-6, Figure 2-7 and
Figure 2-8). A single Power Supply Unit is capable of powering two standard Sector ODU’s, thus allowing
replacement of an ODU Power Supply Module without causing service interruption. The two Power Supply
Modules are load sharing. When Power Supply Module B is removed, +48 VDC will still be present on the
output connector labeled ODU B. When the optional higher power (2W) output ODU is selected, a second
ODU Power Supply is required.

ing includes the following components:
•ODU Enclosure
•RF Electronics
•ODU Controller Card responsible for controlling and monitoring ODU functions and for interfac-
ing with the IDU
The ODU is frequency agile so that the same ODU can typically be used throughout the entire allocated fre-
quency band. Subsequently, this reduces sparing levels.
The ODU meets all National Electrical Code requirements pertaining to lightning and power transients and
meets or exceeds FCC and ETSI regulations pertaining to conducted and radiated Electromagnetic Emis-
sions.
The ODU is sealed against the environment and is capable of functioning in ambient temperatures ranging
from -40°C to +60°C, with up to 100% relative humidity. The ODU can survive steady state winds of 40 m/s
with gusts to 55 m/s (89 mph/123 mph).

5.0 Equipment Receiving, Unpacking and Inspection
5.1 Introduction
This procedure provides information for unpacking and inspecting the PMP equipment prior to physical
installation.
5.2 Receiving and Unpacking the Equipment
At a minimum, check for the following:
STEP 1. Check the outside of the shipping crates for visible signs of damage. Crushed corners
or tears in cardboard may indicate rough handling which may result in hidden damage
to the equipment.
STEP 2. Inventory shipping crates and other packages received in the shipment. Verify that all
items listed on the Electronic Goods Descriptive Inventory or applicable shipping docu-
ment were received. Identify all missing items on the inventory sheet.
STEP 3. Record any noted damage to the outside of the packaging material on the carrier's Bill
of Lading and have the transportation company initial the sheet. All notations should
indicate location and condition.
Example: 1" x 2" scratch on left front (LF) metal panel; not LF panel
scratched. Another example would be 4" x 6" dent in center panel
(not dent in panel).
WARNING! The warranty will be violated if you do not take anti-static precautions when unpacking or
assembling the PMP boards in the PMP shelf. Circuit modules can be damaged by
electrostatic discharge. Ensure that an approved anti-static wrist strap is connected
between the wrist of the person and an electrical ground before handling any of the circuit
modules.
STEP 4. Carefully open the equipment packaging.

9.2 Board Installation
The printed circuit board has a high-density connector on one edge of the board and two black tabs on the
opposite edge of the board (refer to Figure 9-3). Within the chassis, a board slot consists of nylon guides
located at the top and bottom of a board slot, and a high density mating connector located on the mother-
board within the chassis. Refer to Table 5-1, Sector IDU Parts List, for part numbers of the appropriate
cards.
STEP 1. To insert a printed circuit board, vertically align the printed circuit board with the board
slot of the chassis. The majority of the components on the printed circuit board should
be facing towards the right of the chassis. The high-density connector located on the
printed circuit board is inserted into the chassis first, orientated to allow mating with the
corresponding high-density receptacle on the motherboard within the chassis.
STEP 2. The two colored tabs on the front edge of the board are to be held in an extended ori-
entation. Slide the board into the chassis, along the guides, until the two high-density
connectors are close to mating. Use the grips of the black tabs to attach to the chassis
frame, pressing the tabs towards the printed circuit board edge, making a secure con-
nection with the two high-density connectors.
