2 For Voice termination on PSTN lines that "Support", or "Do Not Support" "Battery Reversal / Polarity Reversal" (Answer Supervision). Used in applications to deliver voice over an end- to- end E1 (radio / fiber / HDSL) links. Voice Activity Detection (VAD) to provide spoof Answer Supervision To provide Disconnect Supervision to disconnect hung PSTN lines. Provides complete line protection against difficult field conditions. INTRODUCTION Confidential Slide 2 VCL-CB-INT a). VCL-CB-INT E1 Channel Bank is an intelligent E1 Channel Bank that provides the metering function using Voice Activity Detection (VAD) to provide voice activated "answer supervision" and "disconnect supervision". Suited for Long Distance traffic VoIP termination. VCL-CB-BR b). VCL-CB-BR E1 channel bank provides answer supervision when the called party answers, upon receiving an actual battery reversal of the PSTN analog line. Used in conventional applications to deliver voice over an end-to-end E1 (radio / fiber / HDSL) links. Available with FXO, FXS and E&M interfaces. The E1 Channel Bank solution is available in two versions: VCL-CB, Intelligent E1 Channel Bank Copyright, Valiant Communications Limited

3 FEATURES For Voice termination on PSTN lines that "Support", or "Do Not Support" "Battery Reversal / Polarity Reversal" (Answer Supervision). Uses sophisticated DSP algorithms to provide Voice Activity Detection (VAD) to provide "Answer Supervision" to initiate metering and "Disconnect Supervision" feature to "Disconnect hung / stuck PSTN lines". Ruggedized equipment design. Provide complete protection against the line card failures occurring from induced voltages from AC power lines and lightening strikes and other difficult field conditions. VF (Voice Frequency) specifications are in accordance with G.712, ITU-T recommendations to provide clear voice. Suited for long distance call / traffic termination operators, corporate and ISP customers, who wish to connect their fully digital networks to the PSTN, through the available analog dial-up PTT lines. Available with an E1, 2Mbps interface or a fractional E1 interface (to even start service with less than 10 lines). BENEFITS Also used in conventional applications to deliver voice over an end-to-end E1 (radio / fiber / HDSL) links. Available with FXO, FXS and 2W/4W E&M customer interfaces. Compliance to all the relevant ITU-T recommendations. Modular, 3U high, compact construction provides easy maintenance. Plug & Play - easy to install equipment. Extensive set of alarms Available with easy to use Windows based Graphical User Interface. Synchronization to different user selectable clock sources. Remote Access through TCP/IP (for remote configuration and monitoring - available as an optional extra).
