any interference received, including interference that may cause undesired
operation.
This device complies with Part 27 of FCC Rules. This provides reasonable
protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications.
Any changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.
§15.21 Information to user

alternative form, provided the user can reasonably be expected to have the
capability to access information in that form.
§15.105 Information to the user
This equipment has been tested and found to comply with the limits for a Class
A digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference when
the equipment is operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference in which case the
user will be required to correct the interference at his own expense.
FCC Caution!!!

FCC Compliance Statement
This device complies with Part 15 of FCC Rules.
These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment.
Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the
interference at his own expense.
The broadcast Radio Head (BRH) solution is a new paradigm for the Next-Gen
Digital Terrestrial Transmission (DTT). Deployed in a Low-Power Low Tower
(LPLT) topology, it can create uniformly high signal strength to support
Direct to Mobile (DTM) indoor reception.
LPLT enables efficient spectrum reuse and can also supplement conventional
High-Power High Tower (HPHT) deployments.
The Low-Power Low Tower (LPLT) networks for which this BRH Sub-system has been
developed and expected to operate to provide Broadcast services in High
Population Density/Low Population Density Areas.
The BRH Sub-systems operate in a 722 – 728MHz (Channel 56) band while avoiding
interference to the other licensed operations.

Pole mounting provision
- The connector side of the BRH Unit must be facing down
- All below connectors should be plugged in first a. GPS Plug b. Satellite Input c. ATSC 3.0 Output d. Ethernet plug e. Lightning Earthing
- An active Power plug with – 48V input voltage should be connected to the BRH Unit
- Securely fasten all screws on the Mounting brackets of the BRH Unit and the pole
EMS Providing
- Please refer to the ‘BRH EMS User Manual’ available after EMS login for users with Operators and Admin privileges
- Refer to the section, ‘EMS Workflows’—►provisioning—►`Provision a Device’
- The MAC Address of the Unit will be displayed on the unit for your reference
- Once the Device is provisioned and shows up in the BRH DEVICES list EMS provisioning procedure is completed
Power Up Procedure
- Once the Unit is installed and provisioned in EMS, follow steps (2-9) to power ON the Unit
- Check if the Ethernet plug being connected to the Unit has Internet access. Once done, connect the Ethernet plug
- Check if the F-type DVB-S2 plug is receiving a signal on EMS configured backhaul frequency. Once done, connect the F-type connector as DVB-S2 input
- Connect the N-type plug to GPS Receiver Antenna
- Connect the Output N-type plug to Transmission Antenna
- Verify that the Power Connector output gives – 48V
- Once below four plugs are plugged into the Unit securely, connect the power plug to the Unit at the very end, a.) RJ-45, Internet Connectivity b.) F-type, DVB-S2 Input c.) N-type, GPS Receiver d,) N-type, ATSC 3.0 output
- Unit boots up in —5mins after which the Unit should show up as active on the EMS login for the assigned Operator and statistics sent by the Unit should be visible on the EMS
- An active unit would start transmitting once GPS lock is achieved and according to configured settings on the EMS

The below diagram describes the pin configuration for the input power supply of +48V towards the Enclosure side.
Note: Above configuration has been provided for the connector on the
Enclosure side and not on the input plug
Caution: Please verify the voltage supply on the input connector plug to
match the above configuration before connecting to the BRH Unit
Do’s
- All connectors should be plugged in only after the BRH Unit is securely mounted on the pole
- After complete installation of all components, LNB Antenna, BRH Unit, etc, all should have a common ground
- Make sure – 48V is provided to the Mini-Con-X power supply connector according to provided pin diagram
- Make sure the transmitter antenna is properly connected to the BRH Unit before connecting the power supply
- Power ON the BRH Unit only after checking the common ground of the complete BRH System
- Please use a low-loss/high-power handling cable with a minimal length between the BRH Unit and Antenna systems
- The power plug should be connected at the very last
- BRH Unit should have access to EMS over connected Ethernet
- MAC ID of the BRH Unit should be registered on the Network and IP address should be assigned using an active DNS server
- On an active running BRH Unit, if the power plug is removed, a wait time of 4 minutes is expected before connecting back the power plug
- For any maintenance of the BRH Unit, EMS ‘Shutdown’ command should be used, and a wait time of 1 min is needed before removing the power plug
- BRH Unit should be added and defined on EMS before getting powered on. Please refer to the User Guide available at https://brh.saankhyalabs.com for instructions to define the current BRH Unit on EMS
Don’ts
- Removing the power plug and connecting it back immediately will not power up the unit properly
- During active operation of the BRH Unit, the transmitter antenna radiates RF energy. Do not stand in front or touch the antenna during active operation
- Under lab conditions, do not power ON the BRH Unit without connecting high power attenuators & antenna on the transmission port. Electronics on the BRH Unit will be damaged if an active transmission is done without connecting the proper attenuator and antenna
- BRH Unit should not be opened. Warranty will be void if done so
The device is unreachable on the network
Possible Cause
| Steps to Veri|
Steps to Resolve
---|---|---
Equipment is Powered Off| Verify if BRH Unit is drawing at least
300mA or more| 1. Remove the power plug from the BRH Unit

DHCP Server failed to assign an IP address| Verify if the MAC ID of
the BRH Unit is recognized by the DHCP server| 1. IT team should add
the MAC ID of the BRH Unit to their list of recognized devices
2. [Good to have] DHCP Server should have MAC ID to IP binding
3. Once done, remove the Ethernet plug and connect it back to BRH Unit
4. Ping the IP address of the BRH Unit after a couple of minutes
The power plug on BRH Unit was removed and connected back immediately| |
1. Remove the power plug from the BRH Unit
2. Wait for 4 minutes
3. Connect the power plug to BRH Unit again
4. Unit takes around 4 minutes to boot up completely and connect to EMS
BRH Unit is not transmitting after “Power On”
Possible Cause| Ste • s to Verify| Ste • s to
Resolve
---|---|---
BRH Unit is not provisioned on EMS| Check if the Device is
provisioned on EMS with MAC ID| 1. Follow EMS Guide and provision the device
with the MAC ID of the Device
2. Select proper configuration during provisioning of the device
BRH Unit is provisioned but EMS is still showing the
unit is down| Check if the Unit,
1. Is powered ON
