PertSol iNterceptor – Lawful interception System

iNterceptor: One Stop LI Solution

PertSol iNterceptor is a unified Lawful Interception System for network operators and service providers which is fully compliant to the international standards and has a proven track record. It is a complete solution which is capable of handling both circuit switch and packet switch traffic from both legacy as well as latest telecom technologies including PSTN, 2G, 3G, 4G, LTE, NGN, IMS etc.

The core purpose of iNterceptor is to intercept the traffic and convert intercepted traffic into a format suitable for delivery to the National Authorities or Law Enforcement Agencies, over a secure network. It can also retain the intercepted traffic for future use by the LEAs.compliant to the international standards and has a proven track record. It is a complete solution which is capable of handling both circuit switch and packet switch traffic from both legacy as well as latest telecom technologies including PSTN, 2G, 3G, 4G, LTE, NGN, IMS etc.

iNterceptor along with PertSol iNteliProbe forms one of the most comprehensive interception solution available in the market. PertSol iNteliProbe supports capturing 100% traffic, decoding the traffic from layer 2 to layer 7 and then either transmittal of interception of data and decoded data to the LEAs or its storage for future use. The probes actively support capture and reconstruction of all non-encrypted IP, voice traffic this includes reconstruction and capture of VoIP calls, TDM calls and IP traffic reconstruction. 

iNterceptor solution is designed to change and adapts as per latest network upgradation and technologies. It protects investments through its modular setup, accommodating network expansion as well as network changes. It can also integrate with existing Lawful Interception solution incorporating it in a centrally managed unified solution.

iNterceptor: Benefits

High Performance Mediation

iNterceptor is capable of handling network with very high throughput requirements. It can handle multiple 100 Gbps links and is capable of selecting required traffic from these links. PertSol iNteliProbe have been tested and implemented for traffic up to 40 Gbps per probe.
The integrity check mechanism periodically checks the network elements and if required correct the erroneous states. It will query the network element for the placed intercepts and add missing intercepts, remove invalid intercepts, etc. This mechanism is used to detect and correct both network flaws as well as tampering with the interception solution. In case of correction of an erroneous state, this will be notified to the operator.

Integrity Check Mechanism

Extensive Interface Adapters

iNterceptor has a vast range of Input/Output adapters which makes it compatible with all the available access technologies and network equipment of all the major equipment providers. If required, customer-specific Input or Output adapters can be developed.
iNterceptor allows configuration of multiple Input and Output Adapters to be combined in one system and support any situation like inter-working between different technologies or scaling upto include latest technology. Due to iNterceptor’s modularity, telecom operators can leverage their investment for a longer duration and scale up their network with more flexibility.

Modular Architecture

Support Hybrid Network

Due to its design philosophy, iNterceptor can support hybrid networks with equipment from different vendors on same server. When networks grow or change, iNterceptor can easily be extended to cater for the growth in traffic volumes or new types of network elements.
Unified solution for all interception requirements of a service provider which is compliant to international standards like 3GPP, ETSI, ATSI, ANSI, CALEA and others. It also complies with local LI regulations of many countries across the world.

Compliance

Proven Field Record

PertSol’s LI is a proven and mature solution that continues to benefit from functional enhancement and feature evolution. It has been deployed in varied networks, enabling TSPs / Law Enforcement Agencies to benefit.
