CLEER 24-Port Coax Managed Switch
What are these solutions?
The NVT Phybridge CLEER is a Layer 2+ Ethernet data switch that provides a complete parallel voice network over existing telephone cabling. The solution allows for a non-disruptive, quick and easy way to deploy IP telephony and Unified Communications (UC) applications. The NVT Phybridge CLEER comes in a 24 port model. It is necessary to have one EClink Adapter for every active port on the NVT Phybridge CLEER.
Where can I buy the NVT Phybridge CLEER solution?
NVT Phybridge solutions are available through our Distribution Partners. Our list of distributors is constantly growing, please contact us directly for a list of distributors.
What is the competition?
NVT Phybridge is the only company to competitively offer robust solutions that leverage existing infrastructure to provide POE and Ethernet to an endpoint at distance of 2000 feet or greater.
How does the NVT Phybridge CLEER work with VLANs?
VLANs are not required when deploying the CLEER. The CLEER and EClink Adapters act essentially like a “physical” VLAN, this is done by isolating the IP voice traffic to the parallel voice network provided by the CLEER system. The CLEER has a default configuration of VLAN 1 with all untagged configuration. This will pass all untagged VLAN traffic or remove the tag from VLAN 1 for data to and from the CLEER and EClink Adapter. If you need to configure your IP phones to work with any fixed VLANs (because you may already be using VLANs on your corporate data network), then you will need to configure the CLEER to handle this VLAN traffic.

Who has tested the NVT Phybridge CLEER?
Multiple manufacturers, VARs and vendors have tested the NVT Phybridge CLEER. Please contact us directly for a list of partners.
Do these products support all major VoIP manufacturers?
Yes. Any IP PBX device is supported as the NVT Phybridge CLEER is configured as a layer 2+ switch.
Does the NVT Phybridge CLEER support fiber interfaces?
The CLEER will work with both Multi Mode Fiber (MMF) and Single Mode Fiber (SMF), the limitation is in the GBIC module (rate).
How is QoS handled?
Because of the point to point topology of the EClink Adapter to the NVT Phybridge CLEER, customized QoS configuration is not normally required. In most instances network configuration is not required but if required QOS can be setup on the switch, please see technical training and manuals for information.
What is the maximum PoE Class IP device/phone that can be supported?
Based on the IEEE 802.3af standard, operational testing is required to determine if the Class 3 IP device you have will work in your unique network topology (the longer the wire length, the less power is available to the IP device.) First, please verify the manufacturer’s IP device power consumption specification, if it is less than 10.6 W then you may be able to use a standard EClink Adapter, you will need to test your IP device in the final network topology to ensure the line power draw and IP device power draw does not exceed the 10.6 W. A quick test is to plug the IP device into the EClink Adapter and put the IP device into maximum power consumption. For an IP phone this is usually the ringing state (maximize the ring volume), if the phone does not restart or shut down then your IP device and line load is drawing less power than the 10.6 W maximum. The EClink limits the current drawn on the RJ45 PoE port. If the power draw of the IP phone (device) and line length exceeds the power that can be provided by the CLEER for the IP phone, then it may not power up or will reset during operation. If the problem persists re-test the same IP phone at a shorter cable length to verify that problem is related to the IP phone drawing more than the maximum rated at the desired line length.
What IP devices are supported?
All Class 1 and Class 2 and some Class 3 IEEE 802.3af compliant IP devices are supported.
