Slide 1
VCL-CB, Intelligent E1 Channel Bank
INTRODUCTION
• 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.
The E1 Channel Bank solution is available in two versions:
• 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.
