SunnyStar Co., Ltd

SunnyStar Co., Ltd TE410 4 Port 3.3V PCI ISDN BRI VPMOCT128 Echo Cancellation telephone accessory

SKU CH-67T0-V9R8Q

Four-port 3.3 V PCI ISDN BRI card with a 128-channel hardware echo-cancellation module for Asterisk telephony servers

  • Four-port ISDN BRI interface for multi-line telephony
  • Hardware VPMOCT128 module provides 128-channel echo cancellation
  • 3 V PCI slot compatibility for modern motherboards
  • Up to 10× I/O speed improvement lowers CPU load
  • Supports E1, T1 and J1 signalling on each port

4-port ISDN BRI PCI card

The TE410 3.3V PCI card provides four ISDN BRI ports and includes a VPMOCT128 hardware echo cancellation module. It is designed for telephony servers running Asterisk or similar IP-PBX software that require low-latency voice processing across multiple digital lines. The card targets system integrators building custom VoIP gateways or legacy PBX migration projects.

3.3 V PCI slot required with 64-bit bus support

The card operates only in a 3.3 V PCI slot, which is typically found on newer motherboards and in 64-bit PCI bus architectures. It supports E1, T1 and J1 signalling selectable per card or per port, enabling translation between different line standards. I/O speed improvements of up to 10 times reduce CPU load and allow higher card density per server.

Install into a compatible 3.3 V PCI slot

Installation requires a motherboard with a 3.3 V PCI slot; 5 V-only slots will not work and may damage the card. The VPMOCT128 module must be seated firmly on the main board before insertion. Common issues include missing kernel modules, incorrect interrupt assignment and signalling mismatches between E1, T1 and J1 modes on individual ports.

Questions about this item

Which card configuration should I pick for my Asterisk server?

The TE410 with the VPMOCT128 module provides four ports and 128 channels of hardware echo cancellation in one bracket.

What does the ten-times I/O improvement mean for my server?

It lowers CPU load so you can fit more cards in the same chassis without overloading the processor.

Will this card work in a 64-bit 3.3 V PCI slot?

Yes, it requires a 3.3 V PCI slot, which is standard on newer motherboards and 64-bit PCI bus architectures.
