D-Link DVX-8050 – XStack USB Channel Bank Gateway for DVX-9000 PBX Systems with Modular Telephony Ports & Redundancy Support

• The D-Link DVX-8050 is an XStack USB Channel Bank Gateway designed especially for D-Link DVX-9000 PBX systems.

• It extends the functionality of Asterisk-based IP-PBX systems by adding modular telephony interfaces through a USB 2.0 connection.

• The DVX-8050 connects directly to the Asterisk IP-PBX server via USB 2.0, eliminating the need for an intermediate PCI card.

• Its modular internal design supports different combinations of FXS, FXO, BRI ISDN, E1/T1, and I/O ports according to system requirements.

• Multiple DVX-8050 units can be connected to a single DVX server using different USB 2.0 ports or a USB 2.0 hub.

• The unit supports optional high availability and full PBX redundancy for DVX-9000 series Enterprise PBX systems, with automatic failover to a backup server when activated by software license.
