PTP SOLUTIONS GUIDE 39
1. Doesn’t my Link Guard All Risk Extended Warranty cover lightning damage to my pTp radios?
Yes, the Link Guard All Risk Extended Warranty does cover the cost of replacement for a damaged PTP
300, 400, 500 or 600 radio in the event of a lightning strike. However, because the PTP-LPU can prevent
the damage from occurring, you can eliminate the cost of taking down the damaged unit and installing the
replacement unit, plus the downtime between the time the radio was damaged and when the replacement
unit is installed. In addition, the attractive price point of the PTP-LPU means a fast return on investment,
especially when you factor in higher service availability.
. Why does each pTp 400 or pTp 600 Series radio require two Lightning protection Units?
Each PTP 400 and PTP 600 radio requires one PTP-LPU installed near the radio on the wall, tower or mast,
and one PTP-LPU installed at the cable entry point of the building in which the network resides. The PTP-LPU’s
two protection methods – line-to-line and line-to-ground – can stop a surge in power within 5 nanoseconds,
ensuring maximum protection against damage. Each PTP-LPU End Kit (PTP 400/600) includes two LPUs,
the required installation hardware and cables (excluding the drop cable and connection to the user’s network).
Two PTP-LPU End Kits are required for each link.
3. Why does each pTp 300 or pTp 500 Series radio require only one Lightning protection Unit?
Each PTP 300 and PTP 500 radio has lightning protection capability built into the radio, so there is no need
to install an external lightning protection unit on the tower or wall adjacent to the radio. You need only one
external lightning protection unit (PTP-LPU) per radio, installed at the cable entry point of the building in
which the network resides. Each PTP-LPU End Kit (PTP 300/500) provides one LPU, the required installation
hardware and cables (excluding the drop cable and connection to the user’s network). Together the lightning
protection built into the PTP 300 or PTP 500 radio and the external PTP-LPU offer excellent lightning
protection, although 100% protection is neither implied nor possible.
4. If I already have a Transtector Surge Arrestor, the ALpU-ORT, should I replace it?
If you already have Transtector ALPU-ORT units installed with your links and the units are working
satisfactorily, you can continue to use the Transtector surge arrestors. However, as you add PTP 300, 400,
500 and 600 links to your network, you should deploy those new units with PTP-LPUs. In addition, the
PTP-LPU has an improved design which provides excellent grounding, ruggedness and ease of use with a
projected 10-year lifespan. If your Transtector units have been in place for a significant length of time, you
may want to replace the Transtector surge arrestors with the newer PTP-LPUs to benefit from the units’
advantages. PTP-LPUs can be added to existing deployments with relative ease.
5. Do the pTp 100 and 00 radios share the same technology as the pTp 300, 400, 500 and 600?
Because PTP 100 and 200 Series radios are based on Canopy® technology, they do not share the same
technology that is found in the PTP 300, 400, 500 and 600 Series radios.
6. Can I use the pTp-LpU with pTp 100 or pTp 00 radios?
PTP 100 and PTP 200 Series radios use Canopy’s surge suppressors. The PTP-LPU is designed for use with
the PTP 300, 400, 500 and 600 Series radios.
7. Can I use a pTp 300, 400, 500 or 600 Series powered Indoor Unit (pIDU plus) to power a pTp 00
Series radio?
PTP 200 radios utilize Canopy’s power supply units exclusively. You cannot use the PTP 300, 400, 500 or
600 PIDU Plus devices with PTP 200 Series radios.
