B200P

The B200P is a PCI 2.2 compliant ISDN interface card manufactured by Openvox Communication Co., Ltd in Shenzhen, China. It provides dual BRI S/T interfaces for connecting ISDN basic rate lines to PC-based telephony systems, with an onboard multi NT power feeding circuit that eliminates the need for external power supplies to terminal equipment. The card occupies a single PCI slot and is designed for integration into Asterisk, FreePBX, and other open-source PBX platforms.

The B200P uses standard PCI 2.2 architecture for broad motherboard compatibility and features two independently configurable BRI ports, each supporting up to two concurrent voice or data channels. The onboard power feeding circuit delivers the standard -48V phantom power required for NT mode operation, allowing direct connection to ISDN phones and terminals. Typical BRI S/T interfaces operate at 192 kbit/s total bandwidth (144 kbit/s payload plus 48 kbit/s overhead), with the S/T reference point specifying a four-wire interface with separate transmit and receive pairs.

This card suits telecom integrators, call centre operators, and enterprises building custom PBX solutions on open-source platforms. Buyers should confirm with Openvox Communication Co., Ltd whether the unit ships with the low-profile bracket included, as this affects rackmount and compact chassis installations. The supplier is based in Shenzhen's Futian District, a major electronics manufacturing hub, though buyers will need to verify current MOQ, lead times, and whether CE or FCC documentation is available for their market.

Openvox Communication Co., Ltd is located in Futian District, Shenzhen, Guangdong Province, China, with its registered address at 518000. The company is classified as an imported-tier supplier on the platform, with a harbor trust tier. Its response rate is currently 0.00 percent and average response time is zero hours, which indicates the supplier has not engaged with buyer enquiries through the platform's messaging system. Buyers should factor this into their outreach strategy and consider alternative contact channels.

The supplier's profile does not disclose founding year, employee count, annual revenue, factory size, or specific client references. No certifications, test reports, or quality management systems are listed in the available data. The B200P is positioned as a PCI telephony card for open-source PBX integration, with dual BRI S/T interfaces as its core feature. Buyers should request company registration documents, product compliance certificates (CE, FCC, RoHS), and sample availability directly from Openvox Communication Co., Ltd before committing to volume orders.
