Four-port PCI voice board

The Sangoma A104D is a four-port PCI voice board that provides T1 and E1 carrier connectivity for telephony systems. It fits into a standard PCI slot and presents four RJ-45 network interfaces for line termination. The board is supplied with mounting clips and cables for a 2U installation. It targets integrators building carrier-grade voice platforms.

Sustained carrier load

The board uses a high-performance PCI interface designed for continuous operation in critical telecommunications infrastructure. It handles simultaneous T1 and E1 traffic across all four ports without relying on burst-only throughput. The architecture is built for the constant frame timing and signalling demands of carrier networks. Long-term reliability is a design focus for deployment in production environments.

PCI bus constraints

The PCI host interface limits total bandwidth to the bus specification, which constrains aggregate throughput when all four ports run at full line rate. Each port operates at the native T1 or E1 rate, so the combined load must fit within the available PCI bandwidth. System integrators must verify that the host platform provides sufficient bus capacity for the intended channel count. No other interface or protocol is supported by this board.

Questions about this item

How much power and heat does the A104D produce when running all day?

The A104D is a passive PCI voice board with no on-board fan; power draw and thermal output are minimal and handled by the host system.

What must my server already have to install this A104D?

An available PCI slot and four RJ-45 cables for the T1/E1 network connections.

Will the A104D work alongside older Sangoma cards I keep in the same chassis?

Yes, each A104D occupies one PCI slot and presents four independent RJ-45 ports, so it coexists with other PCI telephony cards without resource conflicts.
