Solutions for Fixnet Providers

Aarenet’s systems pervade all requirements and offer excellent tools for system operations.

Europe still counts for more than 25 million ISDN subscribers. Business customers with multiple device connections or with PBX’s depend on the functionalities of the ISDN connections. A rapid substitution of all ISDN connections in the customer base is not realistic.

Aarenet’s VoIP systems conform to all requirements of voice communication by Fixnet Service Providers. The availability of the full ISDN functionality and SIP trunks is a must for business customer as well as the possibility to use cloud based virtual PBX functionality. For residential customer functions as call-filters to protect customers from unwanted calls or fraud protection mechanisms are needed.

The system comes with own smartphone clients and a very powerful UCC ‘’Unified Communication and Collaboration’’ solution. Support of Web RTC and Click to Call is also supported. A very powerful API allows interconnection to different customer systems. Automated adaptive spamfilters can block unwanted nuisance calls from call centers.

Rollout and Operation

The automated provisioning of customers devices such as CPE’s, IP-Phones or others is key to enable a fast and smooth rollout of VoIP- services. During operations, automatic generation of changes of configurations and the seamless download to customer devices is mandatory. In Aarenet’s VoIP-systems the configuration sets for the various CPE’s is generated directly and downloaded in the devices automatically. The provisioning of the customer devices may happen before shipment or by download after installation and bringing into service.


In instances of malfunctions of devices at the customers premises the customer services representatives of a Telecom Service Provider are often blind sighted and are unable to access system and service related information. Contrary to legacy ISDN-installations where the NT’s (Network Termination Units) are part of the network and being operated and serviced by the provider, many VoIP solutions do not allow to remote access the devices at the customer’s site. This handicaps or inhibits the localisation and analysis of incidents by the provider’s customer service.

Aarenet’s VoIP Systems offer the provider’s customer service departments the capability to access the CPEs (Customer Premise Equipment) from the systems administration unit and query operational information. Whether an ISDN connection is active or a device is connected may be checked. The end-to-end monitoring of the system permits the remote location of failures at the customer premises.
