Intelligent E1 Channel Bank
Technical Specifications
 

Product Description

Orion Telecom Networks Inc. offers Intelligent E1 Channel Bank, VCL-CB with Voice Activity Detection (VAD) to provide voice activated "answer supervision" and "disconnect supervision" to connect VoIP (Voice over IP), Voice over Frame

E1, Intelligent Channel Bank

 
Relay and Voice over ATM networks to analog PSTN (POTS) lines that do not provide any type of answer supervision / battery reversal functions. The interface to the analog PSTN (POTS*) lines have been ruggedized to provide complete protection against line card failures which occur from induced voltages from AC power lines and lightening strikes and difficult field conditions.
