OLUTION ARCHITECTURE

The mobile phone has access to functions and features comparable to

an internal extension, such as callback and conference. Internal parties

who call the mobile extension maintain full functions on such features as

callback and camp on from operator. Additional phones can serve as

alternate answering locations using a specific dialing procedure.

To map and route calls between the PLMN subscription and the exten-

sion in the PBX, it is recommended to have an agreement with a local

mobile phone operator. No extended software or functions is needed on

the mobile phone itself.

If an agreement with a local mobile phone operator is not available, the

recommended configuration is to use the Aastra Mobile Client (AMC). If

not using AMC, a user may call a predefined number in the PBX from

any mobile phone and receive a dial tone. The user can either manually

dial, using a phone book or calling card service after validation, or enter

a valid PIN code.

5.4.6 SIP DECT (OMM) System

Aastra SIP DECT is the first-hand offer for cordless users in MX-ONE.

The radio infrastructure integrates with MX-ONE via IP/SIP and the cord-

less users/handsets are registered in the MX-ONE as SIP extensions.

The extensions/handsets are managed through MX-ONE Manager

Provisioning. SIP DECT uses “synchronization-over-the-air” to distribute

synchronization signals throughout the base stations (RFP’s) in the

synchronization area. Software update of the base stations (RFP’s) is

done over the air. MX-NE provides full integration for the Aastra 600c/d

cordless handsets, basic support is also available for the Aastra 142d

cordless handset.

The Open Mobility Manager (OMM) supports features such as; update

of handsets over the air, messages to/from handset(s), basic alarms

from handset, man-down support (terminal de-pendent), terminal loca-

tion services and message acknowledgement handling. Additionally, the

OMM system can be integrated with external applications such as

different alarm systems, Messaging applications, networks and e-mail

using standards based protocols, such as XML or POP. As the DECT

handsets register as SIP extensions, the necessary SIP user licenses

need to be present in the system.
