Dialogic 4-Channel E1 Fax Board
Dialogic Brooktrout TR1034+P4H-E1-1N-R
4-Channel E1 Fax Board
A hardware fax board built for the transition era — full TDM fax over E1/PRI on one side, T.38 fax-over-IP on the other, on a single Universal PCI card.
Why this board still matters
Plenty of fax servers still run on E1/PRI trunks, and the Brooktrout TR1034 is the card that has quietly handled that traffic for two decades. It’s a genuinely dual-purpose board: on the TDM side it terminates a fractional E1 circuit and speaks V.34 and T.30 straight to legacy PBXs and carrier lines. On the IP side, the same board speaks T.38 fax-over-IP and interoperates with SIP and H.323 gateways, so it can sit on either a traditional trunk or a VoIP network without a forklift upgrade.
That flexibility is exactly why it shows up so often in regulated environments — document management and business-process-automation platforms built around Sarbanes-Oxley, HIPAA, or Basel II compliance still lean on fax as an auditable, legally recognized delivery method, and the TR1034 gives IT teams a way to keep that channel alive while everything around it migrates to IP.
What’s actually on the card
4-channel fractional E1
Terminates an E1/PRI circuit at 4 channels, with the Technology Expansion Capability (TEC) upgrade path available if you later need to light up more channels on the same physical card family.
V.34, T.38, T.30
Full V.34 support for fast, reliable TDM fax connections, T.30 for standard fax session control, and T.38 for real-time fax relay across an IP network.
Tested against major IP-PBX vendors
Dialogic has run interoperability testing against IP-PBX and gateway platforms from Cisco, Avaya, and Alcatel-Lucent, so drop-in deployment into existing VoIP infrastructure is a known quantity, not a lab experiment.
Universal PCI, H.100 bus
Fits Universal PCI slots and connects to the H.100 bus for multi-board fax server builds, with RoHS-compliant construction and low power draw for dense chassis deployments.

The E1 channel-density family
The +P4H-E1-1N-R is the 4-channel entry point into a wider TR1034 E1 lineup. If your fax volume outgrows it, the same card family scales up channel-by-channel rather than forcing a different board architecture.
Channel counts per SKU in the Universal PCI E1 series — higher-density SKUs may require Product Manager approval to order.
