RedSelector® – Switching
RedSelector performs intelligent call switching. Using the DNX®/INX™ hardware, the RedSelector supports a wide range of signalling protocols including SS7, ISDN, CAS and H.323. The desktop application for configuring and administrating circuit and routing options in RedSelector is RedSelector Manager.
The configuration of RedSelector is performed through a series of routing tables. These tables allow each call to be routed either to an alternative trunk, or to a service application. For each call, the destination number and/or the originating number can be examined as criteria for routing the call. Originating address (CLI/ANI) information is typically used for facilities such as call barring. Most routing decisions are based on the destination number (DID/DDI) dialled. Time-based routing may also be implemented based on specific times of the day, particular days of the week, or special days such as holidays.
Alternatively each call will route to a default trunk.
Unless a destination number is configured to map to a different destination number, the outbound call destination number field will inherit the destination address received on the inbound call. The received originating address will also be forwarded and used in the originating address field for the outbound call.
RedSelector provides a range of routing applications such as number translation services, least cost routing, freephone routing and rules-based routing.
In addition, protocol conversion may also be performed. Over 100 protocols are supported such as SS7 variants, Q.931, R1 and R2 CAS, D3/D4 AMI, DPNSS and Q-Sig, and also H.323 (voice) and T.38 (fax) Internet telephony protocols. Bridging between circuit switched and packet switched networks is also supported.
