E1 / T1 Voice Echo Cancellers - Highlights

  • The echo-cancellers are "user configurable" for 64ms. bi-directional, or 128ms. uni-directional echo cancellation. The user selection is made through a user configurable software interface command.

  • User Selectable Tail-End Side (tail-end side is the one which must face the two-wire part of the network from where the echo "originates"). The originating side is "opposite" to the one at which an echo is heard.

  • Option for user to select data or voice channels for selective echo cancellation. This feature allows the user to use selected time-slots for data transmission to enable data / CCS signaling transmission (data mode), while keeping the echo cancellation "ON" on the remaining time-slots (voice mode), on which echo is required to be cancelled.

  • Supported E1 signaling formats: 30B+D PRI ISDN signaling, R2 CAS Signaling, SS7 signaling (on any user selected time-slot). All signaling options are USER SELECTABLE.

  • Supported T1 signaling formats: 23B+D PRI ISDN, C7 Common Channel Signaling (on any user selected time-slot), D4 Robbed-Bit and SLC-96 signaling. All signaling options are USER SELECTABLE. TCP/IP remote access for remote configuration and control.

  • Redundant Power Supply (Optional - to be ordered additionally) E1 / T1 circuit by-pass in event of power supply failure.
  • E1 / T1 circuit by-pass in event of echo canceller card removal from chassis.
  • Analog data / fax (2100 Hz) tone disable detection. Allows fax and analog modem data transmission through automatic echo-cancellation enable / disable function.
  • Meets ITU-T G.164, G.165 and G.168 recommendations.
