Description

The VCL-CB E1 Channel Bank is used in applications to deliver voice over an end-to-end E1 (radio / fiber / HDSL) links. Features include completeline protection against difficult field condition. The E1 channel bank 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.

The VCL-CB- E1 Channel bank offers all types of analog interfaces including FXO, FXS and 2W/4W E&M interfaces, that may be required to deliver voice over an end-to-end E1 (radio / fiber / HDSL) links.

E1 channel bank provides answer supervision feature when the called party answers, upon receiving an actual battery reversal of the PSTN analog line. Both, the line connect and disconnect functions are provided using the actual battery reversal function of the PSTN analog line (e.g. much like your coin pay-phones).

Available with FXO, FXS and E&M interfaces.
