Chapter 1 Solution Overview
Solution Components
Call Control Components
The Cisco BLISS for Cable solution relies on interoperability with partner systems for various functions
that are not directly supported. The partner systems include multimedia terminal adapters (MTAs),
announcment systems, interactive voice response systems, voice mail systems, billing mediation systems
and electronic surveillance systems.
Cisco BTS 10200 Softswitch
The Cisco BTS10200 provides the call processing intelligence of the network, handling call control for
the establishment and tear-down of telephony calls, the service logic required to deliver services, the
linkages to signaling networks, familiarity with dialing plans, and appropriate hooks to operational
support systems. Release 3.5 of the BTS10200 softswitch is to be used in the solution (three cable
packages in 3.5 release).
The Cisco BTS 10200 consists of four logical components (Figure 1-5) in a distributed architecture:
• Call Agent—The call agent (CA) component serves as a call management system and media
gateway controller. It handles the establishment, processing, and tear-down of telephony calls.
• Feature Servers—The feature servers (FS) provide POTS, Centrex, Tandem, and Advanced
Intelligent Network (AIN) services to the calls controlled by the CAs and also provides processing
for service features such as call forwarding, call waiting, local number portability, and so forth. The
FS processes are independent from the CA process.
• Element Management System—The element management system (EMS) controls the entire Cisco
BTS 10200, and acts as a mediation device between an NMS and one or more CAs. It is also the
interface for the provisioning, administration, and reporting features of the Cisco BTS 10200.
• Bulk Data Management System—The bulk data management system (BDMS) coordinates the
collection of billing data from the CA, and the forwarding of billing records to the billing server.
The EMS and BDMS are colocated on one host machine and the CA and FS are colocated on another
host machine. Interworking of CA and FS with media gateways (MGW) provides PSTN-parity voice
service and a reliable migration platform for next-generation services.
