Data Connect Enterprise T1 Channel Bank FXS/FXO with Data

Providing reliable, flexible, and leading-edge solutions for a demanding industry.

Managing your telecommunication needs has never been easier than with DCE products. Data Connect Enterprise provides a flexible and reliable product line that can satisfy any T1 need. Our products will beat your expectations!

Unique DCE features like real-time T1 status on our four line by 40 character (4×40) LCD display, or our automatic, hands-off “Auto T1” configuration tool utilizing artificial intelligence software, and the crystal clear audio quality proves that DCE products are in a class of their own.

Knowing that the DCE product comes ready to perform means that you can spend more time developing important customer relationships.

Data Connect Enterprise offers you a complete line of low cost T1 channel banks including FXS, FXO, or mixed mode FXS/FXO analog interfaces. As a bonus, every system comes with our standard fractional V.35 data port. Add the DCE modular, universal internal power supply system to the list, and DCE crushes the competition. There just isn't a more flexible, feature rich channel bank available anywhere in the world (at any price) that compares to DCE.

DCE products are tough. In the rare case of trouble, our technical support staff is ready to give you the support you need, when you need it. Our 5-year limited warranty means that you can be confident that DCE will always work hard and work well in your T1 application.

FXS, FXO, and Modular

  • FXS – The DCE FXS analog interface provides standard battery and ringing voltages to each of up to 24 loop or ground start analog channels.

Each channel provides:

  • Digital DSP
  • Line current limit from 18ma to 45mA
  • Tx and Rx gain control of -5db to +6db
  • Power down control from 1 to 3 secs.
  • Ring cadence control


  • The DCE FXO analog interface requires a standard POTs analog telephone line up to 24 inputs

Each channel provides:

  • Digital DSP
  • Tx and Rx gain control of -15db to +12db
  • Ring cadence monitoring timer

FXS/FXO Modules

  • The DCE modular channel bank model allows for installation of either a 4-channel FXS or FXO analog daughter card. If the four slots are to be used as data, there is no need to install an analog card.


  •  All DCE channel banks feature a single CSU that is software controlled, software programmable and will self configure to the proper mode right out of the box.

Analog Interfaces

  • The DCE channel bank provides either FXS or FXO analog interfaces, both with digital technology that utilizes a dedicated Digital Signal Processor (DSP) for monitoring real-time line characteristics.

Power Input

  •  All DCE channel banks come in 110VAC,/220VAC with -48V DC input. The only difference between the 110V model and the 220V model is the included power supply cord. All DCE CB24 models are identical.
