A carrier class SS7 Revenue Assurance and Telecom Billing platform for real-time network monitoring, enabling carriers to increase their revenues and improve quality by immediately identifying revenue shortfalls and servicing operational issues.

The Switchblade’s E1 monitor probe extracts SS7 packets from the network, which are converted into Call Detail Records (CDRs) and stored in an enterprise database. The CDRs are accessible to a client workstation with a web browser.

  • SS7 Revenue Assurance web application for CDR analysis.
  • Red Hat Enterprise Linux for 24/7 operation.
  • ITU SS7 ISUP International and National signaling standards supported.
  • SS7 Monitor probes with 8, 16, 32, 48 or 64 E1 pairs capacity.
  • Real-time display of calls-in-progress.
  • User friendly interface for Traffic Monitoring, Statistics, Billing and Channel Usage.

E1 Monitor Probe

The E1 Monitor Probe connects to E1 links via a high-impedance interface to ensure a fully non-intrusive monitoring capability with 8, 16, 32, 48 or 64 E1 pairs capacity and upto 256 SS7 Signalling links. The raw SS7 data packets are streamed to the Switchblade server for processing.

The E1 Probe Monitor is provided standalone as a 1U unit. The E1 links are connected to the E1 Probe via a high-impedance patch panel (1U), which supports 16 E1 pairs (RJ-45s). Each E1 Probe supports upto 4 patch panels.

We have options to allow STM-1 fiber optical networks to be groomed and monitored by the E1 Monitor Probe.

Switchblade Server

The Switchblade Server typically is a rack mounted dual quad-core CPU Server with a 2 to 10 TByte RAID Hard Disk, with 16 to 64 GByte ECC memory running on Red Hat Enterprise Linux.

The Switchblade Server hosts an Enterprise database, which stores the CDRs and operates the SS7 Revenue Assurance web application. This application is used for accessing the CDR database and for the real-time display of calls-in-progress.

A comprehensive set of search queries can be executed from the web-server via the client workstation, the queries extract and display call statistics including accumulated minutes.

For instance:

  • Group Calls by A or B Number.
  • Group Calls by Carrier.
  • Group Calls by Calling Party Category.
  • Group Calls by Release Code.

The investigation of revenue loss varies from call-back services through to fraudulent operation. The Switchblade offers the Carrier detection facilities for a wide range of fraud and access to CDRs to identify the parties involved. The Revenue Assurance Manager can applying action trees to identify the patterns used for these fraudulent calls and by responding appropriately can restore the revenue streams.

The CDR data provided is detailed and includes the time of call, the duration and status, i.e. Answered, A Number, B Number and additional information including Calling Party Category (CPC), Post Dialing Delay (PDD), Release Code (RC), etc.

The accumulation of SS7 CDRs on the signaling link, especially by cellular operators offering international roaming (GSM), provides a basis for charging partner Carriers.
