service provider must configure their network consistent with either the PacketCable, or the Cisco SII, network architecture using compliant network elements. It is the responsibility of the service provider to ensure that their network is CALEA-compliant.

The Cisco SII architecture provides a common architectural solution for intercept of IP communications (voice and data). It uses SNMPv3 as the control protocol and places control of lawful intercept (LI) on a mediation device (third party product) instead of on call control equipment. It also provides a common interface for mediation devices and call control equipment. Depending on your network type, you can use either the Service Independent Interception Provisioning procedure, or the PacketCable Electronic Surveillance Provisioning procedure.

Release 3.5 also supports CALEA call content reporting. Both the call data and call content are supported for call types and scenarios for basic calls and feature calls such as call forwarding, call waiting, etc. Call content allows capturing voice in a replicated RTP stream sent to the LI server by using the control commands (COPS) to the Intercept Access Points.

The Cisco BTS 10200 Call Agent provides the full CALEA functionality, Packet Cable Electronic Surveillance Specification for both call identifying information and call content (voice conversation). There are two methods of call-content used, based on the Network Architecture: Packet Cable Intercept and Service Independent Intercept.

Packet Cable Intercept

To enable the call content delivery in the network as a whole, the Edge/Aggregation Router/CMTS must support COPS, and the trunking gateway must be capable of supporting MGCP extensions for CALEA operation, especially the hairpin wiretap scenario. Additionally, SIP support at the Cisco BTS 10200 must be enhanced to support CALEA call content delivery. This is applicable for call redirection from the intercept subject that spans across multiple Call Agents.

Service Independent Intercept

To enable the call content delivery in the network as a whole, the Edge/Aggregation Router/CMTS and trunking gateway must be capable of supporting SNMP extensions for CALEA operation.

Release 3.5 includes a new auditing enhancement feature—auto recovery of hung CICs. This tool audits unreachable endpoints caused from temporary network disconnectivity or congestion, and recovers the endpoints when they become reachable.

New OAMP Features

The Cisco BTS 10200 Softswitch Release 3.5 includes many new OAMP features. These features include:

•Ensuring that the collection mechanisms employed within the Cisco BTS 10200 guarantee no loss of data between collection intervals.

•Support for disabling CLI and Corba provisioning during software upgrades.

•The Cisco BTS 10200 ensuring that no calls are blocked or denied due to unavailability of billing management resources in either the call agent or EMS.

•Provisioning the allowed and disallowed standard UNIX services on the EMS and Call Agents.

•The Cisco BTS 10200 issuing applicable event reports from the Oracle DMBS engine.

BTS 10200 specifications

Cisco Systems BTS 10200 is a robust platform designed to meet the demands of modern telecommunications. This session border controller (SBC) facilitates the management of voice over IP (VoIP) traffic, enabling secure and efficient communication across diverse networks. The BTS 10200 plays a critical role in integrating voice and data services while ensuring high-quality user experiences and regulatory compliance.

One of the standout features of the BTS 10200 is its ability to support a wide range of protocols, making it highly versatile. It is compatible with both legacy systems and modern IP-based solutions, ensuring seamless interoperability. This adaptability allows service providers to migrate to next-generation networks without disrupting existing services.

The BTS 10200 is built upon a highly scalable architecture, allowing it to handle large volumes of traffic. This scalability is crucial for service providers as they expand their networks to accommodate more users and services. The platform supports hundreds of thousands of simultaneous sessions, which is essential for large-scale deployments such as in mobile and fixed-line networks.

Security is a paramount feature of the BTS 10200. It incorporates multiple layers of security protocols, including encryption and authentication mechanisms, to protect against unauthorized access and potential cyber threats. The platform also features robust filtering and Denial of Service (DoS) protection, ensuring that VoIP services remain stable and reliable even under adverse conditions.

Quality of Service (QoS) management is another critical characteristic of the BTS 10200. It allows for traffic prioritization to ensure that voice signals maintain clarity and reduce latency. Through advanced traffic shaping and management techniques, service providers can enhance the overall user experience even during peak usage periods.

Furthermore, the BTS 10200 supports a wide array of management and monitoring tools, enabling network administrators to gain insights into performance metrics, traffic trends, and system health. This data-driven approach allows for intelligent decision-making and proactive maintenance.

In summary, the Cisco Systems BTS 10200 is a powerful, secure, and scalable solution for managing voice and data services in today's complex telecommunications environment. Its combination of protocol support, robust security measures, QoS capabilities, and management tools positions it as a key asset for service providers looking to enhance their offerings and ensure reliable communications for their users.
