port and the Switch/Router the device is connected to
should not exceed 100m/328ft. This length includes the
connection between the PTP 820E and the PoE Injector
(X1 + X2 ≤100m/328ft in the figure to the right).
•
The length of the cable connecting the customer
equipment to the PoE injector should not be longer
than 10m (according to ANSI/TIA-568 standard).

Connect the second side of the GND cable to
the main or terminal ground bar of the site.
4
Perform a resistance test between the 2 lugs of the
GND cable and verify that the result is 0-2 ohms.
Notes:
The unit’s earthing screw terminal shall be permanently
connected to protective earth in a building installation in
accordance with applicable national code and regulations
by a service person.
A 2-pole circuit breaker, a branch circuit protector, suitably certified in accordance with applicable national code and
regulations, rated maximum 20A, shall be installed for full power disconnection in a building installation.
Any outdoor antenna cable shield shall be permanently connected to protective earth in a building installation.
Connecting to the Unit:
1. Connect your laptops LAN port to the MGT port on the PTP 820E.
2. Configure an IP address on the laptop within the same subnet as
the PTP 820E unit. The default PTP 820 IP address is 192.168.1.1. Set
the PC address to e.g. 192.168.1.10 and subnet mask to
255.255.255.0. Record the initial settings before changing.
3. On the laptop, open the Internal Protocol (TCP/IP) Properties page
and set the parameters shown in the figure on the right.
4. Open a web browser (Internet Explorer or Mozilla Firefox), enter
the default IP address “192.168.1.1” in the Address Bar. Once the
Login page opens, enter “admin” in both the User Name and
Password fields, and click Apply.

Changing the Default IP Address
Select Platform > Management > Networking > Local. The Local Networking Configuration page opens.
Select IPv4 or IPv6. The unit will
use the selected protocol when
initiating communications.
Description of
unit (optional)
You can enter an IP address
in IPv4 format (use the IP
address field) or IPv6 format
(use the IPv6 Address field).
Before configuring the radio link, ensure that
both ends of the link have unique IP addresses.

Installing the Activation Key
New PTP 820E units are delivered with a default activation key that enables you to manage and configure the unit.
Additional feature and capacity support requires you to enter an activation key cipher in the Activation Key Configuration
page. Contact your vendor to obtain your activation key cipher.
If the activation-key-enabled capacity and feature set is exceeded, an Activation Key Violation alarm occurs and the Web
EMS displays a yellow background and an activation key violation warning. After a 48-hour grace period, all other alarms
are hidden until the capacity and features in use are brought within the activation key’s capacity and feature set.
Demo mode is available, which enables all features for 60 days. When demo mode expires, the most recent valid activation
key goes into effect.
To enter a new activation key, select Platform > Activation Key > Activation Key Configuration. The Activation Key
Configuration page opens.
Enter the activation
key cipher here
and click Apply.
To activate Demo mode,
select Enable here and
click Apply.
Displays the number of
hours that remain before
demo mode expires.

Configuring the Link
The Web EMS provides wizards to configure radio links. The wizards guide you through configuration of the basic radio
parameters and services necessary to establish a working pipe link.
To configure a 1+0 link using the Quick Configuration wizard, select Quick Configuration > PIPE > Single Carrier > 1+0.
Page 1 of the 1+0 Quick Configuration wizard opens.
Set the transmission and
received radio frequency in MHz.
Enter the desired TX signal level
(TSL). The range of values depends
on the frequency and RFU type.
Select On or Off to mute or
unmute the TX output of the RFU.
Select the MRMC script you want
to assign to the radio.
Select the ACM mode: Fixed or Adaptive.
If you selected Fixed in the Operational Mode field, the Profile field
appears instead of these fields. Select the ACM profile for the radio in
the Profile field.
If you selected Adaptive in the Operational Mode field, enter the
maximum and minimum profiles for the script in these fields.
• Fixed ACM mode applies constant TX and
RX rates.
• In Adaptive ACM mode, TX and RX rates are
dynamic. An ACM-enabled radio system
automatically chooses which profile to use
according to channel fading conditions.
Select Yes to configure in-band
management or No if you do not
need in-band management.
If you selected Yes above, select
the management VLAN.
Select this box if you want to use the
Ethernet interface as well as the radio
interface for in-band management.
Review the parameters and click Submit to
complete configuration of the link. After you
click Submit, the unit is reset.

interface for the link.
Select an Ethernet interface or LAG for the link.
Click Create LAG to open a wizard that guides
you through the steps to create a LAG.
• s-tag – All S-VLANs and untagged
frames are classified into the service.
• dot1q – All C-VLANs and untagged
frames are classified into the service.

Link Verification
Verify that the Received Signal Level (RSL) is up to +/- 4 dB from
the expected (calculated) level at both ends of the link.
You can measure the RSL at the BNC port indicated in the figure
to the left. The voltage at the BNC port is 1.XX where XX is the
RSL level. For example: 1.59V means an RSL of -59 dBm. Note
that the voltage measured at the BNC port is not accurate and
should be used only as an aid).
Verify that the Radio Bit Error Rate (BER) is 10E-11 or higher.
If working with ATPC, verify that ATPC is operating as expected
(RSL = reference level).
To display the BER using the Web EMS,
go to the Aggregate PM report (Radio >
PM & Statistics > Aggregate).
To display the current RSL (RX)
using the Web EMS, go to the
Radio Parameters page (Radio >
Radio Parameters).
To display the RSL PMs using the Web
EMS, go to the Radio Parameters page
(Radio > PM & Statistics > Signal Level).
