Cisco BTS 10200 Softswitch Release Notes for Release 3.5 V02
OL-3965-01
New and Changed Information
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: PacketCable Intercept
and Service Independent Intercept.

Packet Cable Intercept

Toenable 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

Toenable 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.
Auto Recovery of Hung CICs
Release 3.5 includes a newauditing enhancement feature—auto recovery of hung CICs. This tool audits
unreachable endpoints caused from temporary network disconnectivity or congestion, and recoversthe
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.
