Do these products support all major VoIP manufacturers?

Yes. Any IP PBX device is supported as the NVT Phybridge PoLRE LPC is an unmanaged networking switch.

Who has tested the NVT Phybridge PoLRE?

Multiple manufacturers, VARs and vendors have tested the NVT Phybridge PoLRE LPC. Please contact us directly for a list of partners.

How is QoS handled?

Because of the point to point topology of the PhyLink Adapter to the NVT Phybridge PoLRE, customized QoS configuration is not required.

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 two 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 PhyLink 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 PhyLink 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 PoLRE 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 PoLRE 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 phones are supported?

All Class 1 and Class 2 and some Class 3 IEEE 802.3af compliant IP devices are supported.

What IP phones are supported?

All Class 1 and Class 2 and some Class 3 IEEE 802.3af compliant IP devices are supported.

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 two 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 PhyLink, 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 PhyLink 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 PoLRE 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 PoLRE for the IP phone, then it may not power up or will reset during operation. To recover, unplug the RJ45 cable from the PhyLink. If the problem persists re-test the same IP phone at a very short cable length to verify that problem is related to the IP phone drawing more than the maximum rated at the desired line length.

Do these solutions support video phone applications?

The PhyLink supports 10 BASET connection speeds, verify with your video phone VoIP device manuals the recommended minimum data bandwidth required.

Will the PoLRE or IP devices work without power?

The PoLRE is the only component that requires connection to a power source. The PhyLink and IP devices plugged into the PhyLink receive their power from the NVT Phybridge PoLRE. The NVT Phybridge PoLRE is a complete PoE solution; no local power pucks or adapters are required for the PhyLink or for the IP device plugged into the PhyLink.

How does the NVT Phybridge PoLRE LPC work with VLANs?
