Rhino CB24-FXS - 24 Lines FXS Channel Bank with Data


The Rhino CB24 FXS Channel Bank acts as a T1 multiplexer (mux) that converts 24 digital channels to 24 analog FXS lines. This permits the usage of the old proven analog wiring inside your building to connect analog telephones as extensions in conjunction with Asterisk digital technology. A Channel Bank can be connected to the PBX system by using a single port on a digital PCI telephony card, thus enabling the connection of a large number of lines to the system.


Thanks to the “Auto Config” feature of the Rhino Equipment Channel Bank you can save much time on the installation. Actually, you don’t even need to learn programming or how to use specific software. Our Channel Bank knows how to install itself. All you need to do is plug it in, and “Auto Config” does the rest. And that’s not all: the Rhino CB24 FXS Channel Bank supports data as well, and is configurable channel by channel.


Our Channel Banks use the latest digital technology and are fully embedded. This makes the risk of a component getting damaged minimum and assures the good functionality of the product. Our warranty stands as a proof of that. We offer the best one on the market: 5-year, limited warranty.

We offer as “standard” what others can’t offer at all

Yes, that’s right. Besides having the unique “Auto Config” feature, our Channel Banks support most of the common start protocols (Immediate, Wink, Loop, Ground, DID) as well as D4 or ESF and AMI or B8ZS. This means that the Rhino CB24 FXS Channel Bank can be installed in almost all situations, including dynamic data channels. And now, the new Channel Banks support Neon Bulb Message Waiting Indicators, which makes them perfect for upgrading hotel lines with Asterisk technology.

We also offer for free a fractional V.35 data port on each system, a port that can be used for the IP router connection.

And perhaps the most important of all: as all of our products, our Channel Banks come with free lifetime support, so that whatever problem you may experience with the device, our support team will handle it in no-time.
