About this Chapter

This chapter introduces the TrangoLINK APEX™ system, features, and its components

TrangoLINK Apex™ 18 User Manual Rev. 1.0 Section: Chapter 1 - Overview Page 11

Introduction

The TrangoLINK APEX™ is a carrier grade high-performance all outdoor point-to-point

wireless microwave system designed for Enterprise, Carrier and WISP networks using

licensed 18 GHz spectrum. The TrangoLINK APEX™ provides a full duplex wireless

connection over the air that is ideal for copper RJ45 Ethernet connections as well as

fiber optics through the use of SFP ports.

The TrangoLINK APEX™ is a Frequency Division Duplex (FDD) radio which provides

low latency of less than 150μs, over 1 million packets per second, and up to 730+ Mbps

of data. The TrangoLINK APEX™ uses VLAN and QoS prioritization to offer great

flexibility in offering high value added services.

Contents

Each TrangoLINK APEX 18 kit comes equipped with (1) APEX18-ODU1A, (1) APEX18-

ODU-2A, and (2) wave guide transitions. POE devices, Fiber kits, Data cables, and

power cables are not included with your system.

management. No data pass through is allowed on this port.

RSSI Digital Display: RSSI value of the link is displayed on the digital display

Slip Mount Latches: Slip-mount installation secures the ODU to the Antenna Assembly

or mounting bracket and allows easy removal during maintenance.

Slip Mount Waveguide Transition: Connects the ODU transmit signal to the antenna

waveguide port.

Chapter 2 - Getting Started

About this Chapter

This chapter discusses the basic steps to get started. The following topics will be

covered in this chapter:

• Connection and Power

• Basic Configuration Concepts

• Management

It is recommended that you first provision and test the radios on the bench before

deploying them in the field. This is a particularly useful exercise for the novice user.

!

Additional accessories are required for complete installation of the TrangoLINK APEX 18

such as power supplies, SFP modules, and antennas.

TrangoLINK Apex™ 18 User Manual Rev. 1.0 Section: Chapter 2 - Getting Started Page 15

Connections and Power

Figure 4: Wiring Diagram

• Connect Ethernet cable between the Apex unit and the POE unit. (Power over

Ethernet can be through either the data or management ports.) Alternately, there

is a 2 pin MOLEX™ connector under the fiber cover for direct -48 DC power.

Please note that when the pins are facing up, the + (Red/Ground) is on the left.

Figure 5: Power Connections

TrangoLINK Apex™ 18 User Manual Rev. 1.0 Section: Chapter 2 - Getting Started Page 16

• Out of Band Management Connection - If connecting to a COMPUTER to the out

of band management port, use a Cross-Over Ethernet cable from the

management port of the IDU to the computer’s Ethernet port.

• When connecting a HUB, SWITCH, or ROUTER, to the GigE ports use a

Straight-Thru cable.

• The Apex unit requires power from a -48Volt power supply either directly or

through the POE power injector. Trango Broadband recommends the use of a

PSUPPLY-1U-48 or PSUPPLY-DT-48 and use of a ferrite suppressors supplied

with the power connector to reduce noise that may couple into the IDU on the

power line. Wrap both the + and – wires one time around the ferrite. See

appendix C for a complete listing of accessories.

You are now ready to configure the radio via the management Ethernet port.

!

If you cannot access the radio management functions via the management Ethernet port, it

is possible that your PC is not set up with a properly routable subnet. If cannot access the

radio via the management Ethernet port, use the Console Programming Cable and attach it

to the Console Port. The proprietary console cable needed for this can be purchased from

your sales manager. Settings and connection steps are found later in this chapter.

Basic - Concepts

The TrangoLINK APEX 18 can be configured using either the Command Line Interface

(CLI), or the Web Browser (HTTP) interface. Although both methods are comprehensive

and powerful, the CLI method provides more functionality. Both methods of radio

configuration require an understanding of the concept of Operation Mode (Opmode).

Opmode Concept

Before logging into a radio, it is important to understand the “Opmode” concept of the

TrangoLINK APEX 18. TrangoLINK APEX™18 can be in one of two operational modes:

Opmode “On” or Opmode “Off.” When in Opmode “Off” the radio is not transmitting,

and it is not attempting to make a wireless connection. Alternatively, when in Opmode

“On,” the radio is transmitting, and is attempting to make a wireless connection. The

radio can still be managed when Opmode is “Off”. The radio default is Opmode “Off” to

ensure that nothing is transmitted until the installation is complete and there is no risk of

unintentional RF radiation.

Default Opmode

Default Opmode setting controls whether opmode will be turned on after the boot

process has completed. If Default Opmode is “Off” and Opmode is “On” the radio will

not transmit upon rebooting. The default setting is Opmode “Off” to ensure that nothing

is transmitted until the installation is complete and there is no risk of unintentional RF

radiation.

TrangoLINK Apex™ 18 User Manual Rev. 1.0 Section: Chapter 2 - Getting Started Page 17

Why is Opmode Important?

Opmode is important since if Opmode is not configured correctly the radio will not

transmit to establish a link. There are also certain functions that can only be performed

while the radio is in Opmode “Off.” The following commands can only be performed

with Opmode “Off”

• Setting / Changing Transmit Frequency

• Enabling Loopback

!

FACTORY DEFAULT OPMODE IS “OFF.” DEFAULT OPMODE SHOULD BE CHANGED

BEFORE RADIOS ARE DEPLOYED. CONSOLE MANAGEMENT IS POSSIBLE

REGARDLESS OF OPMODE.

Mean Square Error Concept

Mean Square Error (MSE) is similar to Signal to Noise Ratio (SNR) except that is

accounts for distortion and interference in addition to noise power. Distortion may come

from several sources such as IF cables that are improperly constructed path

degradations such as multipath or Fresnel zone encroachment. Interference may not

only come from other transmitters on the tower, but also from high power transmitters in

the indoor shelter where the IDU is located or from transmitter located very close to the

cable. There are maximum acceptable MSE values for each modulation which are

useful in determining the quality of the link. The MSE value reported is only relevant to

one tx-rx path, so the MSE of each tx-rx path must be evaluated to verify the link is

operating cleanly. The lower the number the better so a -35dB is better than a -30dB.

The table below shows the maximum MSE value to expect in IF Loopback, Normal

Operation, and Absolute Maximum.

TrangoLINK Apex™ 18 User Manual Rev. 1.0 Section: Chapter 2 - Getting Started Page 18

The maximum power input, measured by RSSI, is as depicted in Table 3. If your RSSI value is

higher than listed for the modulation that you are running, you may incur bit error rates as well

as possible damage to the system.

QPSK: -24 dBm

Table 3: Max Power Input

ACM – Adaptive Code Modulation

The ACM feature of the TrangoLINK APEX™ works in conjunction with the MSE of the

unit. The ACM command is an on/off command. Once ACM is enabled and link is

degraded to the MSE threshold specified, the radio will shift down in modulation and

speed based on the setting of the ACM table (Table 4).
