Remote Terminal Overview
2.1
Introduction
The Remote Terminal provides the interface between network services and the customer premise. The
Remote Terminal is available with various interfaces for customer premise interconnect and communicates
with a Sector Terminal. The Remote Terminal consists of the following components:
2.2
•
Remote ATM Indoor Unit (IDU) containing a Modem and a Remote ATM Controller (RAC) with
four UTP-5 ports
•
One or more Asynchronous Transfer Mode (ATM) Service Modules
•
Outdoor Unit (ODU)
•
Antenna and Mounting hardware
•
An IFL consisting of a single coaxial cable connecting the IDU to the ODU
Remote ATM Indoor Unit (IDU)
The IDU is located inside the customer's facility at a remote site and is connected to an ODU via a coaxial
cable. The IDU is capable of implementing two types of software selectable uplinks: FDMA or TDMA. The
IDU is comprised of the following components:
•
1 rack unit (1U) Remote ATM IDU chassis
•
AC or DC Power Supply
•
A Modem that provides the physical layer wireless communication link between the Remote
Terminal and Sector Terminal
•
Remote ATM Controller (RAC)
•
Optional ATM Bandwith Manager Daughter Card
The 1U Remote ATM IDU Chassis measures 5 cm (H) x 45 cm (W) x 43 cm (D) (1.75” x 17.5” x17.5”). This
chassis can be desktop or rack mounted (refer to Figure 2-1 and Figure 2-2).

Figure 2-4 illustrates a typical RF/Antenna configuration for the ODU. The packaging includes the following
components:
•
ODU Enclosure
•
RF Electronics
•
ODU Controller Card responsible for controlling and monitoring ODU functions and for interfacing with the IDU
The ODU is frequency agile so that the same ODU can typically be used throughout the entire allocated frequency 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 Emissions.
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).

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 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 document 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:
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.
5.3
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).
Carefully open the equipment packaging.
Inspecting the Equipment
STEP 1.
CAUTION!
For each of the PMP subsystems received, verify the equipment received matches the
shipping list by Part Number and Serial Number. Report any discrepancies immediately using the field return procedure outlined in Section 11 of this manual. The TelLink PMP system may be ordered in different configurations. Table 5-1 shows the Part
