Introduction Understanding System Components
1
The DECT frequency band means excellent voice quality and no need to worry about radio
interference with Wi-Fi or Bluetooth devices. DECT offers highly secure communication using a
worldwide standard of advanced algorithms for voice and data encryption, ensuring that conversation
is protected against eavesdropping.
Understanding System Components
The IP930D system consists of these major components:
Handset—A battery-powered mobile handset with charging stand that emulates the user interface
of the ShoreTel IP Phone 230 models.
Base station—A PoE-powered device containing DECT radio and processing capabilities for
wirelessly connecting to handsets and repeaters, and for connecting over Ethernet to the IP
network.
Repeater—A DECT radio and processing component for extending the range of an IP930D base
station.

Introduction IP930D Handset

ShoreTel IP Phone 930D Planning and Installation Guide 11
ShoreTel IP930D Manager—A web-based interface used for system management, including
viewing and modifying configuration parameters, and enabling handset and repeater registration.
ShoreTel IP930D Configuration Tool—A Windows-based program that generates required
configuration files and an installation summary report.
IP930D Handset
The handset is powered by a replaceable lithium-ion battery and features a color LCD. The user
interface on the handset emulates the interface of a ShoreTel IP Phone 230 model.
The handset has volume controls and a mute switch on its left side and a headset jack on its right side.
The four bottom-most keys provide quick one-push access to the transfer, conference, redial, and hold
features.
The handset has a built-in speakerphone for hands-free operation and can also be used with a wired
headset.
The three line appearances can be programmed in the same way as line appearances on other
ShoreTel IP Phones, using ShoreTel Director.
A Menu button permits access to additional system features. Hold down the Menu button for more than
three seconds to access an internal handset settings menu.

Introduction IP930D Base Station
1
IP930D Base Station
The base station unit can be mounted on a desk or wall and uses an RJ-45 connector for network
access and power.
On the front side of the unit is an operational status LED indicator. On the back side of the unit is the
RJ-45 Ethernet connector and a reset button.
For more information, refer to the ShoreTel IP Phone 930D Base Station and Repeater User Guide.
IP930D Repeater
The repeater is an optional component used to extend the range of a base station unit. It can be
powered by either a PoE cable or by a small wall transformer and two meter cable.
The repeater can be mounted on a wall or ceiling. On the front side is an LED indicator that shows the
repeaters status.
For more information refer to the ShoreTel IP Phone 930D Base Station and Repeater User Guide.

Introduction Understanding System and Coverage Limits
1
ShoreTel IP Phone 930D Planning and Installation Guide 13
Understanding System and Coverage Limits
The capacity of the IP930D system is limited by the number of DECT radio channels available in close
proximity to the bases and repeaters.
Frequency Bands
The IP930D system uses these frequency bands:
1920 - 1930 MHz (US)
1880 - 1900 MHz (Europe, Australia, New Zealand)
System Capacities
Each base station and each repeater uses a 12-timeslot DECT radio.
In the US and Canada (US/CA), there are 5 frequencies available for voice: 5 x 12 timeslots = 60
channels maximum.
In Europe, Australia, and New Zealand (EU/ANZ), there are 10 frequencies available for voice: 10 x 12
timeslots = 120 channels maximum.
Each base station can support a maximum of 4 handsets.
Each base can, optionally, support up to 4 repeaters. Adding repeaters does not increase the number
of handsets that a base can support; it only extends the range, or footprint, that those handsets can
roam.
You can daisy chain/cascade repeaters up to a maximum of three (although doing so may introduce
delays).
Capacities (US/CA):
With 1 base and 0 repeaters = 4 handsets
With 10 bases and 0 repeaters = 40 handsets
Maximum combined base units and repeater units = 24 handsets (average)
Capacities (EU/ANZ):
With 1 base and 0 repeaters = 4 handsets
With 20 bases and 0 repeaters = 80 handsets
Maximum combined base units and repeater units = 48 handsets (average)
Capacities are limited to these maximums to ensure that all handsets can be guaranteed non-blocking
voice paths—even when all handsets are on a three-party call.
Note that these IP930D system capacities refer to a single site or airspace within which the handsets
are used; a single ShoreTel system can support multiple IP930D systems in different locations, so long
as there is no airspace contention between them.

Example of a System Layout
This example shows a four-handset IP930D system that uses one base and four repeaters.
As long as component limits for the system are honored, you could alter coverage area or capacity in
this system to suit your needs. For example:
If this system included daisy chained repeaters, coverage dimensions could take on different
shapes.
If more handsets were needed, additional bases and repeaters could be overlaid in the same
locations as the bases and repeaters shown in the example.
For more information about designing a system layout see Chapter 2, Planning.
Topology and Technical Specifications
Each base station requires the assignment of an IP address (DHCP or static).
Each handset requires the assignment of an IP address (static). The IP addresses for handsets must
be in a continuous range (example: 192.168.11.50 – 89).
Each handset uses the same ShoreGear switch IP Phone resources as any other ShoreTel IP Phone.
From a resource prospective, each base can appear to be as many as four IP phones (one for each
handset).

Introduction Call Handoff Limitations and Synchronization
1
ShoreTel IP Phone 930D Planning and Installation Guide 15
An IP930D base supports the same networking features as other ShoreTel IP phones, including
DHCP, VLANs, LLDP, and 802.1x.
In a multi-base (multicell) environment, multicast IP packets are used to communicate among bases.
Therefore, all bases in a single airspace should be on the same IP subnet (this avoids complex
multicast routing configurations).
Call Handoff Limitations and Synchronization
Call handoff is not supported between base stations. Call handoff is supported across repeaters that
are associated with the handset’s registered base station.
Because base-to-base-handoff is not supported, the maximum continuous coverage area of any
installation will be limited to the coverage that can be obtained by using a combination of a base and its
associated repeaters. For this reason, this system is best suited for a single air-space (such as one or
two floors of an office building) and is not appropriate for a campus environment where handsets need
to operate across buildings.
DECT radio synchronization is required between the bases and the associated repeaters that make up
a system. Synchronization between bases and repeaters is done entirely over the air using DECT
spectrum. See Synchronization on page 46 for more information.
Understanding System Management
Managing the IP930D generally requires that you use the same approach and software tools you
would use to manage other ShoreTel IP Phones. Additionally, a web-based interface called
ShoreTel IP930D Manager allows you to:
Verify and modify system configuration
Troubleshoot issues
Reset a base remotely
Enable handset and repeater registration
Check upgrade status for components
See which components are currently in use
See Understanding System Management on page 49 of the Reference Material chapter for more
information about ShoreTel IP930D Manager.

Understanding Networking and Power Requirements
This topic contains information about network and power requirements and recommendations.
Networking Requirements and Recommendations
The following are networking requirements and recommendations:
Assign an IP address (DHCP or static) for each base (required).
Assign an IP address (static) for each handset (required).
Use a switched 10 or 100 Mbps capable network connection to connect to the base
(recommended).
Connect multi-base systems to a common subnet and identify a free multicast address for base-to-
base communications (required).
Power Requirements
The following are system power requirements:
Handset charging stands require a non-switched AC outlet (100-240V 50/60 hz) within two meters
of the charger.
Bases are Class 2 devices and require PoE.
Repeaters require one of these for power:
A non-switched AC outlet (100-240V 50/60hz) within two meters of the repeater.
A PoE wire adapter and Linksys POES5 5-volt PoE splitter for use with a powered Ethernet
connection. (See Using a PoE Wire Adapter and Splitter to Power the Repeater on page 19.)

ShoreTel IP Phone 930D Planning and Installation Guide 19
Using a PoE Wire Adapter and Splitter to Power the Repeater
Using a PoE wire adapter and splitter allows you to install a repeater in a location that does not have a
nearby AC outlet. Use the splitter to provide power only; do not use the Ethernet cable provided by the
splitter. Refer to the illustration below.
Understanding Environmental Requirements
Consider the following environmental guidelines when planning your IP930D installation:
Mount bases and repeaters indoors, in dry and protected areas, and connect these components to
indoor wiring only.
Whenever possible, mount the base near the ceiling, vertically on the wall. Avoid mounting on
metal walls, metal beams, or on concrete structures containing steel reinforcement.
Bases and repeaters must be placed with at least one meter of separation between units. Range
and system capacity might be reduced if components are located less than one meter apart.
IP930D components emit RF radiation that is below all government and industry limits. However, some
devices containing sensitive microphones can be affected by this radiation and should be kept at a
distance from IP930D components.

Planning Understanding Architectural Impacts to Coverage

Understanding Architectural Impacts to Coverage
Construction materials and architectural features at the installation site can greatly impact base and
repeater coverage. In open or outdoor areas, the coverage radius of a base or repeater can be 150
meters or more. Indoors, the distance can drop to as low as 10 meters. In addition, the base mounting
height, nearby metal objects, and interference sources can impact coverage.
Wall Materials
This table shows coverage ranges for some typical wall materials:
Multiple Floors
Many floor and ceiling materials allow coverage to extend to the floors above and below the base or
repeater floor. If that proves not to be the case, find areas where repeaters can link to the base or other
repeaters through stairwells or other openings in the building.
When planning multi-floor installations, it is helpful to think in three dimensions. Here is an example:
Wall Material Coverage Range in Meters
Plaster walls over studs 30-60
Concrete 10-30
Heavily reinforced concrete 0-10
Stone/Brick 30-50
Metal 0-10
None 150-300
