2 Making Handset Ready

In this chapter we briefly describe how to prepare the handset for use, install, insert and charge new
batteries.

Package - Contents/Damage Inspection

Before Package Is Opened:

Examine the shipping package for evidence of physical damage or mishandling prior to opening. If
there is a proof mishandling prior to opening, you must report it to the relevant support center of the
regional representative or operator.

Contents of Package:

Make sure all relevant components are available in the package before proceeding to the next step.
In principle, every shipped base unit package/box contains the following items:

2 x mounting screws and 2 x Anchors
1 x Handset hook
1 x A/C Adaptor
1 x Battery
1 x charger
1 x Handset Unit, 1 x Battery cover

Version 0.4 Page | 7

Damage Inspection:

The following are the recommended procedure for you to use for inspection:

1. Examine all relevant components for damage.

2. Make a “defective on arrival - DOA” report or RMA to the operator. Do not move the shipping
carton until it has been examined by the operator. The operator/regional representative will
initiate the necessary procedure to process this RMA. They will guide the network
administrator on how to return the damaged package if necessary.

3. If no damage is found then unwrap all the components and dispose of empty
package/carton(s) in accordance with country specific environmental regulations.

Before Using the Phone

Here are the pre-cautions users should read before using the Handset:

Installing the Battery

1. Never dispose of the battery in fires, otherwise it will explode.

2. Never replace the batteries in potentially explosive environments, for e.g. close to
inflammable liquids/ gases.

3. ONLY use approved batteries and chargers from the vendor or operator.

4. Do not disassemble, customize or short circuit the battery

Using the Charger

Each handset is charged through the use of a handset charger. The charger is a compact desktop unit
designed to charge and automatically maintains the correct battery charge levels and voltage. The
charger Handset is powered by AC supply from 110-240VAC that supplies 5.5VDC at 600mA. When
charging the battery for the first time, it is necessary to leave the handset in the charger for at least 10
hours before the battery is fully charged and the handset ready for use.

Handset in the Charger

For correct charging, ensure that the room temperature is between 0°C and 25°C/32°F and 77°F. Do
not place the handset in direct sunlight. The battery has a built-in heat sensor which will stop charging
if the battery temperature is too high.

If the handset is turned off when placed in charger, the handset turns on and shows (shortly) the
charging message “The battery is charging”. After a while the display backlight first dims and then turns
off (if not demo mode is enabled). There will be a response for e.g. incoming calls. If the handset is
turned on when placed in charger, the display shows (shortly) the charging message “The battery is
charging”. After a while the display backlight first dims and then turns off.

Version 0.4 Page | 8

Open Back Cover

1. Press down the back cover and slide it towards the bottom of the handset.

2. Remove Back Cover from Handset

Handset Serial Number

The serial number (IPEI/IPUI number) of each handset is found either on a label, which is placed
behind the battery, or on the packaging label. First, lift off handset back cover and lift the battery and
read the serial number.

The serial number is usually needed to enable service to the handset. It must be programmed into the
system database via the SME VoIP Configuration interface.

Replace Battery

Remove Back Cover from Handset. Remove the old battery and replace with a new one.

Version 0.4 Page | 25

Site Survey Mode

To enable Site Survey Mode, do the following step:

STEP 1 On the Service Menu (or Debug mode) scroll down to the Site survey mode > Enable

the Site survey mode to switch from Off to On.

This sets the handset in a state to list all visible bases around it and/or chained to the same base
station(s). Handsets in site survey mode can display up to 5 other handsets with the strongest signal
strength.

In Site Survey Mode the handset MMI shows the RFP (including slave RFP) to which the handset is
locked to and the corresponding signal strength (RSSI).

Valid Inputs: On or Off

Line1: RPN 28 20 03
Line2: -dBm 56 84 78
Line3: FE PP: 1 FP: 4

Parameter/Line Description

RPN

The line contains the list of base stations identified by the handset as RPNs of
the bases in respect to the signal strength values below. Up to 5 RPNs can be
displayed.

-dBm (Signal

Strength)

This indicates the actual signal strength information (RSSI) to the base station
the current handset is locked to and additional RFPs visible. RSSI unit is -dBm.
The RSSI value increases the closer the base is to the handset.
If the base could not be detected, the RSSI value will decrease and after a while
the entry will be deleted, if e.g. the dummy-bearer position has changed or the
RFP is unreachable.

FE PP:XX FP:XX

Indicates the number of sync/CRC errors (Frame-Errors) within the last update
cycle.
This information is only valid for the actual link to the relevant base station.
The PP value is the number of detected Sync/CRC error(s) within the last 100
receiving frames (per sec.). The FP value is the number of received bit
information within the last 100 receiving frames (per sec.). This information is
interpreted as Sync and CRC errors on the base station receiving side.

Version 0.4 Page | 26

SW Version Base station: Current firmware installed on the current Base station the Handset is

location registered to.

Handset: firmware presently installed in the handset.

Nomenclature: Version Date Stamp (for e.g.: 00.21 01-07-2010 00:00).
HW Version Current hardware module used in base station and handset.
DECT Band Operating frequency of system. DECT band includes US, EU, LTAM, SA, N/A options.
IP Address IP address of base station.
MAC Address HW address of base station.
System Name Name describing the SME network. Usually a string of 16 bytes.
Battery Level Current handset battery energy position (in %).
IPEI: HW address of the handset - see description below.

IPEI

The IPEI (International Portable Equipment Identity) is a unique identification of portable part
(handset) and DECT Repeater. The IPEI is formatted and displayed in HEX, OCT, and OCT
nomenclatures.

Demo mode

The demo mode enables constantly backlighting, so be aware of that when this mode is enabled,
backlight saving is disabled and therefore battery consumption will increase.

Wideband

When Wideband mode is enabled (On) the handset supports G722 codec, but to ensure Wideband
audio remember to enable the codec in the base station as well. When Wideband is disabled (Off)
Narrowband codec is used, the option Prefer is not supported at the moment.

Test Tone on OK key

When this feature is enabled (On) a 1 kHz test tone can be put into the audio streaming, e.g. when a
call has been established press the centre key of the handset (where this feature is enabled) and the
test tone is streamed through to the counterpart handset.

Handover

The Handover feature is for Interquartz internal test only (ensure that all settings are set to Off).

Press “Retrieve” option to re-connect the call placed on hold.

Call Transfer (Blind)

While “Connected”, press the Hold option, to put the call session on hold.
Enter the transfer destination number.
Next, Press the “Transfer” option to transfer call session from Originator to the Target
Transfer. The Facilitator handset performs transfer procedure and returns to Idle mode (On
hook mode)

7 Flow Graphs – Call Transfer

Some Definitions – Call Transfer

There are three actors in a given transfer event, each playing one of the following roles:

Transferee: the party being transferred to, the Transfer Target.
Transferor: the party initiating the transfer.
Transfer Target: the new party being introduced into a call with the Transferee.

The following roles are used to describe transfer requirements and scenarios:

1. Originator - wishes to place a call to the Recipient. This actor is the source of the first

INVITE in a session, to a Facilitator or a Screener.

2. Facilitator - receives a call or out-of-band request from the Originator, establishes a call to the

Recipient through the Screener, and connects the Originator to the Recipient.

3. Screener - receives a call ultimately intended for the Recipient and transfers the calling party to

the Recipient if appropriate.

4. Recipient - the party the Originator is ultimately connected to.

Call Transfer - Requirements

Any party in a call session is able to transfer any other party in that session at any point in that session.
The Transferor and the Transferee are not removed from a session as part of a transfer transaction.
This requirement is needed so for e.g. ring-back on transfer failure will not be lost.
The Transferor is aware of whether or not the transfer was successful.

Types of Call Transfer

There are three different methods to transferring calls depending on the SIP Server the customer may
be using (most SIP server call transfer method is based on the Refer method). They are as follows and
will be explained in more detail below:



Basic or Unattended Transfer - Basic Transfer consists of the Transferor providing the Transfer
Target's contact to the Transferee. The Transferee attempts to establish a session using that
contact and reports the results of that attempt to the Transferor. The signalling relationship
between the Transferor and Transferee is not terminated, so the call is recoverable if the Transfer
Target cannot be reached. Note that the Transfer Target's contact information has been exposed
to the Transferee. The provided contact can be used to make new calls in the future.



Basic or Unattended Transfer with Consultation - Transfer with Consultation Hold is the same as
the Basic Transfer above but involves a session between the Transferor and the Transfer Target
before the transfer actually takes place. This is implemented with SIP Hold and Transfer feature.



Attended Transfer - The Transferor places the Transferee on hold, establishes a call with the
Transfer Target to alert them to the impending transfer, places the Target on hold, then proceeds
with transfer.

8 Flow Graphs – Conference Calls

The intent of this document is to describe how to establish conference call sessions between one or
multiple parties from a typical handset MMI. Secondly, explain the conference call scenarios in a SME
network – using call flow diagrams.

Call Conferencing Operation

In call conference process architecture, a user agent (UA), known as a participant, establishes a SIP
dialog with another UA, known as a focus. The focus is the central point of control, authentication,
and authorization. This section defines the operation of a focus and participant UAs. Note that only
the signalling (SIP) needs to be centralized; the media can be centrally mixed, distributed, or even
multicast.

Types of Conference Calls

There are three main types of conference calls approach explored from the perspective of different
user agent (UA) types (usually known as participant). We briefly describe two of them.

Conference unaware participant:
The simplest user agent is able to dial in to a conference and to be invited to a conference. Any
conferencing information is optionally conveyed to/from it using non-SIP means. Such a user
agent does not usually host a conference.

Conference aware participant
A conference-aware user agent supports SIP conferencing call control SUCH as a conference
participant. A conference-aware UA should be able to process SIP redirections.
A conference-aware UA usually renders to the user any information about the conference
obtained from the SIP conference package/feature.
