4 Solution components description
4.1 8378 DECT IP-xBS hardware
There is an indoor version with integrated antennas.
There is an indoor version with external antennas connectors. The external antennas are
not provided with the product (external antennas for 8378 DECT IP-xBS are the same as
external antennas for TDM Base stations IBS, see the ALE catalog to have the list of
available external antennas).
There is an outdoor version with external antennas. The external antennas are provided
with the product but can be changed thanks to connectors.
4.2 ALE compatible Call Servers
The IP-xBS solution is integrated with OXO CONNECT EVOLUTION CS and OXO
CONNECT CS and their embedded DHCP and TFTP servers. By default, the embedded
DHCP and TFTP servers are well configured to serve the xBS.
4.3 DECT handsets
ALE AGAP DECT handsets (8232, 8242, 8262, 8262 Ex) and ALE GAP DECT handsets
(8212) are supported.
Third party GAP DECT handsets can be used but Business Partner is responsible about
technical aspects.

5 Wizard OXO
The wizard hereunder will help to understand which IP-xBS features you should use on the
foreseen deployment.
For an easy deployment only few concepts like PARI CREATION, DYNAMIC IP
CONFIGURATION, xBS AUTO-DISCOVERY, AUTOMATIC AIR SYNCHRONIZATION are
used and most of them are automatic.
Conditions for easy deployment:
✓Less than 80 xBS
✓Continuous buildings with no interruption of air synchronization (no branch offices)
✓No mix with TDM BS
✓Dynamic IP parameters (CS and xBS are placed in the same DHCP domain)
If any of the above is not fulfilled, it becomes a complex deployment.
For a more complex deployment additional concepts like SYNC CLUSTER, SITE could be
used.
Before using the wizard hereunder, you must have an idea of the number of base stations
needed in the deployment. It can be estimated based on the buildings dimensions, the
number of users and the needed traffic thanks to the rules given in the doc[2]
Note: It is recommended to first work on a paper plan and do a site survey in areas where
air synchronization could be difficult to achieve. Even with only a few 8378 DECT IP-xBS it
is recommended to do a site survey.

5.1 IP-xBS PARI creation
Before configuring the Call Server, a PARI (<= 80 xBS) must be obtained on the ALE Business
Portal.
PARI numbers are managed on site through the eBuy "DECT installations management (PARI
codes)" page, follow the link[8]: https://ebuy.businesspartner.alcatel-
lucent.com/codepari/menu_paricode.aspx (restricted access).
PARI is given in octal (TDM DECT) and in hexadecimal (IP-DECT) format.
These PARI will represent the identity of the DECT system for a group of up to 80 xBS.
OXO OMC PARI configuration:
There is only one PARI in the system shared between IP-xBS and TDM IBS base stations
⇒OMC →Dect →DECT / PWT ARI / GAP →ARI

5.2 xBS auto-discovery
The xBS connected on the IP network are automatically discovered by the call server (given
they are in the same broadcast domain as the CS) either for an initial deployment or for an
addition of new xBS to existing deployment. Only a very reduced configuration is needed on
call server. This automatic discovery needs to be first enabled on CS side and is limited in
duration.
OXO auto-discovery activation must be done here:
⇒OMC →Subscribers / Base stations List →Auto Provision
After clicking « Activate Temporarily » in menu Auto Provision, the system is ready to accept new IP
equipment.

5.2.1 Manual xBS deployment
xBS can also be manually provisioned in the Call Server before being connected to the
network. After configuring SITE, PARI, the base station’s MAC address must be configured
manually:
On OXO:
•Create an IP terminal:
⇒OMC →Subscribers / Base stations List →Add →IP-xBS (Base Station)
•Enter MAC address in the subscriber details
•Optionally choose the site and the cluster to which the base station will be
attached

5.3 Automatic air synchronization
The DECT base stations transmissions need to be time aligned in order that a DECT
handset can perform roaming and handover between the bases. To achieve time alignment
of xBS, the synchronization by air is used. The xBS can synchronize by air to other xBS
provided that they are close enough to each other (see doc[2])
The air synchronization tree calculation is automatic.
An automatic air synchronization tree can be composed of a maximum of 80 bases
belonging to the same PARI and the same SITE. The tree supports a maximum of 24 levels
(hops).
There is one internal synchronization tree per SITE per PARI.
The tree root is called SYNC MASTER, the algorithm calculates which xBS is the best to
become the SYNC MASTER at a given instant. When the radio environment changes, the
position of the SYNC MASTER and the shape of the tree may change automatically. The
calculation of the tree is made continuously and the tree changes if we add base stations, or
if a better tree is calculated as a function of the RSSI levels than as a function of the number
of hops. The change of the tree has no impact on the on-going audio communications.

5.4 SYNC MASTER
Definition:
A SYNC MASTER is the 8378 DECT IP-xBS root of the internal synchronization tree.
Characteristics:
The SYNC MASTER is the one being the root of the synchronization tree. It is selected automatically
by the air synchronization algorithm.

5.5 SITE
Definition: A SITE is a group of 8378 DECT IP-xBS located in the same geographical
location where it is possible to do handover.
Purpose: It allows to distinguish for example a Head Quarter from Branch Offices using a
different SITE Number Id.
Characteristics:
Roaming is possible between SITEs (HQ SITE 1 and BO SITE 2 for ex.), handover is not
possible.
The SITE mandatory component is the 8378 DECT IP-xBS which has the role of DATA
SYNC PRIMARY. It is automatically selected by the CS.
When handover is not requested (for example between head quarter and branch office)
then 8378 DECT IP-xBS infrastructure are separated on different SITEs to minimize the IP
network traffic between the 8378 DECT IP-xBS.
The number of possible SITEs is 20.
By default, all xBS are in the same SITE. The SITEs are defined by the system
administrator who may also change the assignment of an xBS to a SITE.
There is one internal synchronization tree per SITE per PARI. This tree can be composed
by several islands spread in several SYNC CLUSTERs.
Trees are not shared between SITEs. Trees are not shared between PARIs
Example 1: PARI is shared between two SITEs (HQ and BO)
On OMC you can change the SITE number associated to an xBS in the detailed settings of
this xBS.
PARI 1
SITE 1
SITE 2
PARI 1
Head Quarter
(ex. With < 80 bases)
Branch Office 1

5.6 DATA SYNC PRIMARY
Definition:
The DATA SYNC PRIMARY is an 8378 DECT IP-xBS in charge of synchronizing the data
between all the 8378 DECT IP-xBS of a SITE (including the time synchronization tree). Its
role is to centralize all data and to copy them to all 8378 DECT IP-xBS attached to it.
Purpose: Handover is only possible between data synchronized xBS thanks to the DATA
SYNC PRIMARY.
Characteristics:
There is a single DATA SYNC PRIMARY per PARI inside a SITE.
The DATA SYNC PRIMARYs are automatically assigned by the Call Server.
The Automatic Redundancy of DATA SYNC PRIMARY is managed by the Call Server. In
case of failure of the DATA SYNC PRIMARY, the Call Server selects a new one and notifies the
other xBS of the SITE.

5.7 SYNC CLUSTER
Definition: A SYNC CLUSTER is a set of 8378 DECT IP-xBS which are synchronized (time
aligned) together at the DECT radio interface.
Purpose: A chain of SYNC CLUSTERs allows to constrain the way the xBS are
synchronized together. The use of SYNC CLUSTERs is reserved to problematic and
exceptional situations. It is recommended to request help to ALE technical support before
using them.
See doc[1] and doc[2] for more details.
5.8 Internal Synchronization
Definition:
A set of 8378 DECT IP-xBS inside the same SITE which are synchronized (time aligned)
together are known as using INTERNAL SYNCHRONIZATION.

5.9 RELAY xBS
Definition:
The RELAY xBS is the 8378 DECT IP-xBS where the IP audio communication (using the
RTP protocol) is established with the distant phone and where the signalization is
established. It relays the audio communication and the signalization to the xBS where the
handset is moving.
Characteristics:
The RELAY xBS does not necessarily handle the radio link with the handset.
A single 8378 DECT IP-xBS can handle up to 11 relays.
5.10 RELAY xBS load sharing
Definition:
The IP-xBS solution is using RELAY xBS load sharing by choosing a low loaded xBS inside the same
SITE to establish the media and the signalization. This will avoid any RTP resources saturation in an
8378 DECT IP-xBS where the communication traffic is high.
Characteristics:
The RELAY xBS is the base station where the DECT DLC layer is running for a given handset
whatever the handset location.
