Installing the Unit
This Quick Setup guide provides instructions for installing and configuring a 2+0 dual-polarization direct-mount
pipe configuration using XPIC. These instructions can also be used for a direct-mount 1+0 configuration that can
later be upgraded to 2+0 with an additional activation key and minimal software configuration, no additional
hardware installation required.
Hardware configuration, including the type of mediation devices required, differs for different configurations. For
other configurations besides the 2+0 dual-polarization direct-mount XPIC configuration described in this Quick
Setup guide, refer to the PTP 820C Installation Guide.
When tightening the captive screws, use 20 Nm
torque for radio-antenna, radio-mediation device,
and mediation device-antenna connections. In order
to avoid misalignment, screws should be tightened
progressively.
Note
Do not remove the transparent
pressure window located on the
antenna interface.

To install a PTP 820C unit in a direct-mount dual-
polarization configuration
Prior to the installation,
follow the antenna
manufacturer’s instructions
to use the circular adaptor.
(Remove the existing
rectangular transition, swap
the O-ring, and install the
circular transition instead.)
1Connect the OMT
Kit to the antenna
and secure it with
four screws. Verify
the existence of the
O-ring.
2 3 Connect the PTP
820C unit to the
OMT Kit using the
four M8 captive
screws and washers
supplied, and tighten
the screws.
To connect an optical Ethernet cable and SFP
Split the connector
into two separate
LC connectors, one
for each fiber.
Remove the gland cap
and rubber from the
gland body
Slide the gland cap into the cable.
Slide the rubber into the cable.
Insert the fibers with the connectors
one by one into the cable gland.
Secure the cable to the lip of
the gland using a tie wrap.
This is to prevent the cable
from slipping from the gland
when raising the cable to a
radio unit on a tower. Connect the fibers to the
SFP transceiver. Listen for
the “click” to ensure that
they are fully inserted.
Remove the tie wrap securing
the cable to the gland and
connect the connector into the
PTP 820C connector.
Hand-tighten the gland to the radio
unit until there is full contact between
the gland and the radio unit and
hand-tighten the gland cap.
Secure the cable to the
gland using a tie wrap.

and rubber from the
gland body
Insert the power
cable into the gland. Insert the power cable wires
into the power connector.
Match “+” to the 0V wire and
“-“ to the -48V wire. Plug the power cable
with connector into the
PTP 820C power
connector.

Cable Grounding
No grounding is required for optical (SFP) cables.
External shielded CAT5E cable should be grounded to the
antenna tower at the top (next to the PTP 820 unit) and the
bottom of the external run and every 50m using the PTP 820
Grounding kit for CAT5E F/UTP 8mm cable.

To connect the PoE Injector cables
The total length of the cable between the PTP 820C port and the
Switch/Router the device is connected to should not exceed 100m/328ft.
This length includes the connection between the PTP 820C 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).

the GND cable to the main
or terminal ground bar of
the site.
4Perform 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.

Grounding for MultiCore Mediation Devices
MultiCore Mediation Devices (MCMDs) are not grounded. In order to add grounding, the MCMD can be connected
to the PTP 820C using a Grounding Jumper. To connect the Grounding Jumper:
1
When you secure the MCMD to the antenna,
connect one end of the Grounding Jumper to
the lower left screw that connects the MCMD
to the antenna.
2
When you perform the PTP 820C grounding
procedure described above, connect the
other end of the Grounding Jumper to the
PTP 820C grounding screw, along with the
PTP 820C grounding cable. The order in
which you place the two cables is not
important.
Connecting to the Unit
1. Connect your laptops LAN port to the MGT port on the PTP
820C.
2. Configure an IP address on the laptop within the same
subnet as the PTP 820C unit. The default PTP 820C 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.

Installing the Activation Key
New PTP 820C 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.

you through the steps to create a LAG.
Select the Attached Interface type
for the service that will connect the
radio and Ethernet interfaces:
Select the first radio
interface for the ABC group.
 s-tag –All S-VLANs and untagged
frames are classified into the service.

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. Make sure to
assign a script that supports XPIC.
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.

Link Verification
Verify that the Received Signal
Level (RSL) is up to +/- 3 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).
