Clarent Gateway Technical Specifications

General Description

Internet telephony gateway for connecting telephone voice and fax calls over the Internet or a TCP/IP intranet. The Clarent Carrier Gateway interacts with billing, call routing and network administration in the Clarent Command Center™ software package.

Product Highlights

Voice Quality: Clarent uses a unique combination of DSP and host-based voice processing for toll-quality voice transmission. Clarent Carrier Gateways use industry-standard G.165 echo cancellation.
Universal Ports: All ports on Clarent Carrier Gateways can handle voice, real-time fax, and data traffic transparently giving service providers maximum flexibility. H.323 Standard-Based Product: Clarent Carrier Gateways support G.711, G.723.1, and G.729a codecs as well as Q.931 signaling.

Scalability: 8-port to 120-port gateways can be “mixed and matched” and stacked to achieve the desired density in a given point of presence. Clarent Carrier Gateways support SS7/C7, PRI-ISDN, T1, E1, Analog, and PBX connections.

Flexibility: Service Editor, an IVR toolbox, allows comprehensive customization of the voice interface.

Availability: Optional PSTN fall back if the IP network is unavailable.

Manageable: Standards-based network management support via SNMP, MIB-II, and LanManager. Clarent products have been designed to easily integrate into telecommunications management network (TMN) environments.

Remote Management

Clarent Gateways can be managed using telnet, SNMP, or Clarent GatewayView.
Clarent Gateways support SNMP V1 with a comprehensive management information base (MIB). Service providers can set parameters, poll devices for performance statistics and status information, and receive alarms when faults occur.

The Clarent GatewayView, a client application, lets network administrators view and control gateways remotely from another Windows™ NT computer. Port statistics can be viewed and ports can be managed remotely.

Each Clarent Gateway keeps log files for diagnostics. These log files can be streamed to a customer-defined IP address for centralized diagnostics analysis and troubleshooting.
