The Cisco Broadband Local Integrated Services Solution uses the Cisco BTS 10200 Softswitch,
Figure 10-2, as a call agent (CA). Call agent hosts used in this version of the solution are Continuous
Computing Based Systems and a Sun A1000 disk array. Each call agent host supports a minimum of 49K
DS0 channels with a throughput of 100 DS0 calls (POTS) per second (setup and tear-down), with an
average hold time of three minutes. It provides at least 99.999 percent availability.
The call agent application is active on only one call agent host platform at a time, and switches to the
standby call agent host platform under failure conditions. The result is that call agent host failure and
switchover events are invisible at the signaling point.
The call agent includes a scalable, open host that provides SS7 interfaces, alarms, and a reliable IP link
between the call agent and media gateways. The following sections provide detailed call agent
specifications for the Continuous Computing-based systems and Sun disk array.
