INTRODUCTION
The SecureMesh™ Extender Bridge combines the functionality of a SecureMesh Wide Area Network (WAN)
relay node and a SecureMesh Neighborhood Area Network (NAN) access point to create an integrated
product.
Each SecureMesh Extender Bridge employs a 5 GHz SecureMesh WAN radio with an array of 8 directional
antennas to interoperate as an element of the SecureMesh WAN and a 2.4 GHz SecureMesh NAN radio with
an omnidirectional dipole antenna to act as an access point for SecureMesh NAN devices. The Extender
Bridge uses the same enclosure as an Extender to house the WAN antenna array, the WAN Extender circuitry,
and optional 802.11b/g 2.4 GHz Wi-Fi access point circuitry as well as the NAN Collector circuitry.
Extender Functionality
The Extender Bridge’s 5 GHz SecureMesh WAN radio uses its array of eight, beam-switched, directional
antennas to provide extended range and full 360° coverage and acts as a relay node within the SecureMesh
WAN network.
The Extender Bridge offers an Ethernet port for WAN client devices, allowing a single client device or, by using
an external IP router or Ethernet switch, many client devices to connect to the WAN. If deployed using a
SecureMesh Power Service Unit (PSU), the Ethernet port for WAN client devices is made available through the
PSU’s port.
Collector Functionality
The Extender Bridge provides the functionality of a 2.4 GHz SecureMesh NAN Collector, supporting
SecureMesh electric meters, gas meters, load control switches, and other SecureMesh NAN devices to create
a wireless mesh subnetwork of the SecureMesh Neighborhood Area Network. The Extender Bridge
establishes time synchronization and coordinates overall operation of the NAN subnetwork defined by its
associated nodes and then routes NAN traffic to/from the UnitySuite Head-End Software via the SecureMesh
WAN.

PREPARING FOR INSTALLATION
Required Pre-Provisioning Equipment
The following equipment is required to support pre-provisioning of the Extender Bridge, typically in a lab
environment:
A PC with Trilliant’s TstBench software installed and connected to the same Ethernet network as the
SecureMesh Extender Bridge. The Extender Bridge’s default IP address for Extender functionality is
192.168.0.2; the default IP address for Collector functionality is 192.168.0.3.
A power supply, typically one of the power supplies listed as an Extender Bridge accessory.
A CAT5e, Ethernet cable for connecting the Extender Bridge’s Surge Protector to a 24V PoE power
supply and the site’s Ethernet network
Required Outdoor Equipment
The following equipment is required to support field installation of the Extender Bridge:
A power supply, typically one of the power supplies listed as an Extender Bridge accessory. For all
outdoor installations, the PSU-1024-33 SecureMesh Power Service Unit is recommended unless an
Uninterruptible Power Supply is available.
A CAT5e, UV-protected, Shielded-Twisted Pair (STP) Ethernet cable with ground wire for connecting
the Extender Bridge’s Surge Protector to the PoE power supply.
One of the accessory mounting brackets listed above or a similar mounting bracket providing a vertical
pole with a 1.25‖ to 2‖ diameter that is a minimum of 18‖ from any structure to the side of the Extender
Bridge. The vertical pole must extend a minimum of 5‖ above the horizontal surface of the bracket.
A 10 AWG (or larger) ground wire of sufficient length to connect the Extender Bridge to the primary
grounding point of the utility structure to which the Extender Bridge will be mounted.
A magnetic level to ensure the Extender Bridge is plumb.
Self-fusing rubber insulation and sealing tape such as Scotch® 130C or 2228 Rubber Mastic Tape
Installation Location
In general, a SecureMesh Extender Bridge should be installed in a location that will not obstruct the radio
signals to and from the SecureMesh Extender Bridge. The SecureMesh Extender Bridge should be installed in
a location that meets all of the following guidelines:
Installation and wiring of the SecureMesh Extender Bridge must conform to all local electrical codes
and ordinances.
The installation location must be either owned by the utility or the utility must have access rights to the
location.
The installation location must be able to provide adequate power. Note that the 24V Power Service
Unit requires 90-265 VAC 50/60 Hz power.
SecureMeshTM Extender Bridge Installation Guide
Trilliant Incorporated page 9 of 26
The Extender Bridge enclosure must be mounted at least 18 feet (5.5 meters) above ground level,
although radio performance and coverage will generally improve as the mounting height is increased.
The installation location must not obstruct radio communications. For example:
— The mounting structure should not block radio coverage or be adjacent to structures that block
radio coverage).
— The installation location must be clear of thick trees or brush growth upon installation and in the
foreseeable future. Foliage in the line of sight with other communicating devices can
detrimentally affect radio performance.
— The Extender Bridge should have an unobstructed view of the sky overhead. The Extender
Bridge relies upon GPS (Global Positioning System) signals to establish time synchronization,
and the strongest GPS signals are available if the device has an unobstructed view of the sky.
Upon startup, the Extender Bridge searches for a GPS signal. If the device cannot detect a
signal, it will be unable to complete startup and will not establish wireless connections with other
SecureMesh WAN devices.
As necessary, adequate space must be available to use a bucket truck.
The installation location must not impede normal maintenance activities (for example, access to the
Extender Bridge’s associated Power Service Unit to replace the battery).
If choosing a streetlight pole installation, make sure the streetlight is providing constant power.
Pre-Provisioning
In general, each Extender Bridge is shipped from the factory with most utility-specific configuration items
already written into non-volatile memory. However, certain information must still be configured prior to
installation.
Provide power to the Extender Bridge, and then configure parameters associated with both Extender and
Collector functionality.
Extender Parameters
To configure the Extender Bridge’s Extender parameters, connect the Extender Bridge to an Ethernet network,
establish a Telnet session to IP address 192.168.0.2 to access the Extender Bridge’s Extender functionality,
and invoke the command line interpreter. Please refer to the ―SecureMesh™ WAN Command-Line Interface‖
(Trilliant document number DP-0985) for complete information.
The following Extender parameter must be configured:
Shared network key (“netkey”) — the shared network key is used by a SecureMesh WAN node to
prove (via an authentication handshake) that the node belongs to a particular network or operator; i.e.,
the shared network key is used to authenticate the SecureMesh WAN node to the SecureMesh WAN
and, reciprocally, authenticate the SecureMesh WAN to the SecureMesh WAN node. The netkey is a
string of 6 to 64 ASCII letters, numbers, or symbols.
If IPsec VPNs are being used (and Trilliant strongly recommends their use), the following Extender parameter
must also be configured:
VPN credentials — the VPN shared secret allows a SecureMesh WAN management tunnel to be
established to the VPN router (note that in automatic provisioning mode, node configuration is provided
SecureMeshTM Extender Bridge Installation Guide
Trilliant Incorporated page 10 of 26
in a secure manner over the IPsec VPN tunnel, requiring the VPN credentials in order to establish the
tunnel and thus necessitating that they be configured before deployment). Because a SecureMesh
WAN node’s IP address may be dynamic (for instance, a node may connect to different IP subnets
through different SecureMesh WAN Gateways), a VPN router will be unable to differentiate between
different VPN clients, and the SecureMesh WAN nodes in a network must all employ the same VPN
shared secret. The VPN shared secret is any ACSII string up to 64 bytes in length, using any
combination of letters, numbers, or symbols.
As an option, Trilliant recommends that the following Extender parameters be configured in order to speed up
the time required for an Extender Bridge to discover other SecureMesh WAN nodes and become part of the
network:
primary frequency – the primary frequency should be configured to be the same center frequency
value as configured for the Gateway to which the Extender Bridge is expected to connect. Specify the
primary frequency in MHz as a four digit number (e.g. 5745).
allowed frequencies – the allowed frequencies defines the various frequencies which the Extender
Bridge will ―hunt‖ for other SecureMesh WAN nodes and Gateways. The range of frequencies should
be configured to the range that will be used by other SecureMesh WAN nodes in this specific
deployment. The range may be specified as ―all‖ or a group of specific frequencies. When specifying a
group, enter each value separately as a 4 digit number (MHz), evenly divisible by 5.
Collector Parameters
To configure the Extender Bridge’s Collector parameters, connect the Extender Bridge to an Ethernet network,
invoke the TstBench software, and establish connectivity with IP address 192.168.0.3 to access the Extender
Bridge’s Collector functionality. The parameters listed below are in Table ND05 74: SSH VPN Configuration.
The following Collector parameter must be configured to enable IPsec VPN:
VPN credentials — the shared secret allowing a SecureMesh NAN data tunnel to be established to the
VPN router (note that in automatic provisioning mode, node configuration is provided in a secure
manner over the IPsec VPN tunnel, requiring the VPN credentials in order to establish the tunnel and
thus necessitating that they be configured before deployment)..The VPN shared secret is an ASCII
string up to 64 bytes in length.
The following Collector parameters may be configured to provide additional security:
Secure SHell security — Secure SHell (SSH) is used to authenticate users and encrypt messages
between the Command-Line Interface (CLI) of the Extender Bridge’s Collector the user’s computer.
The SSH username and password insure that only authorized personnel can access the CLI. Both the
username and password are ASCII strings up to 32 bytes in length.

Grounding and Protecting the Device
The surge protector box should be attached to the
bottom of the Extender Bridge. The surge protector will
be attached using the ground screw as a pivot point
then the box will be swung into place against a mounting
bracket screw.
Remove the ground screw from the base of the
device, and then loosen (but do not remove) the
screw on the same side of the bracket as the
ground screw
Run the ground screw through the lug of the green
ground wire coming from the surge protector and
the hole in the surge protector bracket.
Before tightening the ground screw, remove a
section of the insulation on the ground wire which
will attach to the ground point on the mounting
structure and wrap this section around the ground
screw.
Pivot the box into place such that the other end of
the surge protector’s mounting bracket touches the
loosened screw. Tighten both screws.
Be sure to connect the ground wire to the
grounding point on the mounting structure.
Run the CAT5e cable under the gasket and plug it
into the Ethernet port in the cavity on the device

Attaching the NAN Antenna
Attach the 2.4 GHz NAN antenna to the N-type female
connector as shown in to the right. There are two N-
type connectors at the base of the Extender Bridge:
one N-type connector is open (exposed), and the other
is capped. Use the open connector.
Hand tighten or, equivalently, tighten the antenna using
a torque-limiting tool tighten it to 14 inch-pounds (1.5
Newton-meters), where 14 inch-pounds is
approximately the torque a person can achieve using
one hand.
Use self-fusing rubber insulation and sealing tape to
wrap the antenna bulkhead connector and the antenna
to avoid water penetration of any kind.
SecureMeshTM Extender Bridge Installation Guide
Trilliant Incorporated page 15 of 26
Connecting the Device to a Source of Power
The Power Service Unit can be used to provide PoE power and battery backup for the Extender Bridge.
Please refer to the Power Service Unit Installation Guide for more information (Trilliant document PL-0042A,
Installation Guide, SecureMesh 24V PSU). Alternatively, the site may have its own Uninterruptible Power
System that can be used along with a PoE injector to provide 24V power and data over an Ethernet cable;
terminating in an 8P8C connector as per TIA/EIA-568-B.
Connect the Power over Ethernet (PoE) injector to the Surge Protector
Both power and data are provided over the Ethernet cable connection to the Extender Bridge.
Always use CAT5e (outdoor CAT5) cable that is shielded (Shielded Twisted Pair – STP), UV protected, with a
drain-wire. The Extender Bridge has an auto-sensing Ethernet port and therefore, either a straight through or a
cross-connect cable may be used.
The cable seal gasket (glands) is water-tight and will not allow terminated cables to be passed through. The
cable will have to be re-terminated. Therefore, it may be best to perform the termination on the ground before
beginning the installation.
A sufficient portion of the cable shielding must be available to be connected to the ground bolt.
Run an un-terminated CAT5e cable through the open glands on the surge protector.
Strip the protective coating from the outside of the CAT5e cable to a sufficient length that the shield of the
cable may be connected to the ground lug of the surge protector and the twisted pairs may be connected
to the RJ45 or the connector block. Connect the cable shield (drain wire) to the internal ground lug.
Either terminate the cable from the PoE using an RJ45 connector or terminate all eight cables to the
terminator block. The screw down terminator block is removable from the base board of the surge
protector to ease connections. Please note that the pin-outs of the RJ45 are standard TIA/EIA-568-B. The
screw down terminal block wiring diagram is listed on the main board.

Before tightening, rotate the device to ensure there is ample
room for the omnidirectional antennas to clear the mount
stand and streetlight pole.
Attach the Ground Wire
Connect the Ethernet PoE cable to the Ethernet port at
the base of the Extender Bridge, pushing the 8P8C into
the socket on the bottom of the Extender Bridge until it
locks into place (as shown on the right). The Ethernet
PoE cable should be routed through the water protection
gasket.
Loosen the ground screw at the base of the Extender
Bridge. Remove a section of the insulation on the ground
wire that will attach to the ground point on the streetlight,
and wrap this section around the ground screw and
tighten the screw.
If the streetlight is completely metal, attach the other end
of the ground wire to the mounting hardware. If the
streetlight is a metal arm attached to a wooden pole the
ground wire must extend to a proper ground location.

COMMISSIONING THE EXTENDER BRIDGE
Configuring the SecureMesh Extender Bridge
Assuming the Extender Bridge is properly pre-provisioned, use of automatic provisioning as described in the
―Trilliant Network Element Management System (NEMS) Administration Guide‖ (Trilliant document number
TLT-CS-ADM-94) recommended.
Monitoring the Power-On Sequence
When power is supplied to the SecureMesh Extender Bridge, it
starts a power-on sequence that can be monitored by observing
the pair of LED lights on the underside of the device.
The SecureMesh Extender Bridge must have access to a GPS
signal to complete its power-on sequence and start making
wireless network connections. The power-on sequence takes
up to 15 minutes, depending on how quickly the device can
acquire a GPS signal.
The tables that follow provide detailed descriptions of device
states indicated by the LED lights. When both LED lights are
illuminated and steady, the Extender Bridge has successfully
connected to the wireless network.

APPENDIX
Grounding Guidelines
Proper grounding protects both your SecureMesh device and any equipment connected to it. For the surge
protection circuitry built into the SecureMesh equipment to be effective, proper grounding of the unit is
necessary. Protection is essential if the unit is installed on tall structures or in areas subject to lightning.
Note that the techniques described in this appendix are intended as general guidelines and do not constitute a
comprehensive guide covering all installation scenarios. For maximum protection, contact a qualified
installation specialist who is familiar with your operating environments. If lightning is a threat in your area,
consider a consultation with a lightning and transient protection specialist.
General Grounding Strategy
To ensure optimal reliability, properly ground the metal base of the SecureMesh device. The most efficient
way to ground the device is to use a 10 AWG or larger wire to connect it to a ground point on the structure or
tower.
The three most common grounding points are:
The primary grounding point or the down lead
provided by an existing grounding system at the
installation site. For example, the grounding
system may be provided by a building's AC
electrical system, a streetlight’s power system,
or as part of a tower structure.
A 10-foot or longer copper-clad ground rod
driven into the earth. At a tower with multiple
legs, there will typically be one ground rod per
leg and a ground wire loop connecting each of
the rods as shown in the accompanying picture.
A cold-water pipe. Make sure it is well
connected to earth.

SecureMeshTM Extender Bridge Installation Guide
Trilliant Incorporated page 24 of 26
Making Robust and Lasting Connections
Regardless of the grounding point you use, make sure the connections are capable of retaining low resistance
and integrity over time and with exposure to the elements by use of an antioxidant compound. For protection
against corrosion and rust, wrap all connections with a product such as Scotch® 130C or 2228 Rubber Mastic
Tape.
Grounding Checklist
When grounding a SecureMesh WAN device, use the following checklist to confirm that your installation is
adequately protected from power surges and lightning.
Install all lightning and surge protection devices in accordance with UL 96A installation requirements for
lightning protection systems and the NFPA 780 standard for lightning protection.
Connect a ground wire from the SecureMesh WAN device to a ground system on the utility pole, tower,
or building.
When using outdoor Ethernet cable, use UV protected,
Shielded Twisted Pair (STP) CAT5e cabling that includes a
drain wire. The drain wire and cable shield should be
connected to the appropriate ground location on the
SecureMesh WAN device; typically the ground lug inside the
surge protector or the ground point on the outside of the device.
Leave the other end of the drain wire at the power source
unconnected.
Use the proper size down lead to connect the SecureMesh
WAN device on a roof or tower to the ground system.
Whenever possible, verify that all points of the ground system
are tied together with less than 5 ohms resistance between any
two points.
