Page 4 Alternative DC supply If the PTP 250 is to be powered from a DC supply (either as the primary power source or as a backup to the AC supply), the DC supply must be input to the ODU via a PIDU (not a PoE power supply).
Page 5 Safety and Regulatory Drop cable tester The drop cable tester must NEVER be used at the ODU end connected to power from the PoE power supply. It must only be used at the bottom of the mast with a multimeter. This is because the PoE power supply voltage exceeds the limit allowed in some countries for safe handling in wet conditions and therefore may create a safety hazard.

Page 47: Wireless Operation
This section describes how PTP 250 wireless links are operated, including modulation modes, power control and security. Wireless Transmissions The PTP 250 uses Time Division Duplexing (TDD) transmission, which means that a single frequency channel is used for both Transmit and Receive. This is handled automatically by the radio.

Page 49: Radar Avoidance
PTP 250 User Guide Wireless operation Radar avoidance In regions where protection of radars is part of the local regulations, the PTP 250 must detect interference from radar-like systems and avoid co-channel operation with these systems. To meet this requirement, the PTP 250 implements the following features: ETSI regulations The regulations have radar detection requirements for both master and slave devices.
Page 50: Security
Security The PTP 250 supports 48-bit proprietary encryption for data transmitted over the wireless link. Country of operation Some aspects of wireless operation are controlled, enforced or restricted according to country of operation.

Page 53: Ethernet Bridging
Customer network Transparent Ethernet service The PTP 250 provides an Ethernet service between the Ethernet port at a local ODU and the Ethernet port at an associated remote ODU. The Ethernet service is based on conventional layer two transparent bridging, and is equivalent to the Ethernet Private Line (EPL) service defined by the Metro Ethernet Forum (MEF).

Ethernet port at the local ODU, and (assuming that the wireless link is established) the Ethernet port at the remote ODU. Wireless link down alert PTP 250 offers a configurable email alert which can be set to send the user an email message in the event of the wireless link going down. Back-to-back links PTP 250 will not operate correctly if a direct cabled connection is made between two PoE power supply units.
Page 55: Protocol Model
PTP 250 User Guide Ethernet bridging Protocol model Ethernet bridging behavior at each end of the wireless link is equivalent to a two-port, managed, transparent MAC bridge where the two ports are: Ethernet Port Wireless Port Frames are transmitted at the Wireless port over a proprietary point-to-point circuit- mode link layer between ends of the link.

The ‘reset to factory defaults’ feature provides a means to recover from serious configuration errors, such as lost or forgotten passwords. Use the reset plug (supplied in each PTP 250 ‘Link Complete’ or ‘End Complete’ kit) to reset the unit to factory default configuration, including reset of the country that was selected at first login.
Page 59: Chapter 2 Planning Considerations
............This chapter provides information to help the user to plan a PTP 250 link.
Page 60: Spectrum Planning
For example, at 5.8 GHz in the UK and some other European countries, the RTTT band 5795 MHz to 5815 MHz is barred. With the appropriate configuration for a country in this region, the PTP 250 will not operate on channels within this band.
Page 61: Frequency Selection
Spectrum planning Frequency selection The PTP 250 fully conforms to regional regulatory requirements for radar avoidance. In regions that mandate DFS, the unit first ensures that there is no radar activity on a given channel for a period of 60 seconds before radiating on that channel. Once a channel has been selected for operation, the unit will continually monitor for radar activity on the operating channel.

Page 67: Path Loss Considerations
PTP 250 User Guide Link planning Path loss considerations Path loss is the amount of attenuation the radio signal undergoes between the two ends of the link. Calculating path loss The path loss is the sum of the attenuation of the path if there were no obstacles in the way (Free Space Path Loss), the attenuation caused by obstacles (Excess Path Loss) and a margin to allow for possible fading of the radio signal (Fade Margin).
Page 68: When To Install Connectorized Units
Chapter 2 Planning considerations When to install connectorized units The majority of radio links can be successfully deployed with the integrated PTP 250. However the integrated units may not be sufficient in some areas, for example: Where the path is heavily obscured by dense woodland on an NLOS link.
Page 69: Grounding And Lightning Protection
The actual degree of protection required depends on local conditions and applicable local regulations. Motorola recommends that PTP 250 installation is contracted to a professional installer. WARNING Electro-magnetic discharge (lightning) damage is not covered under warranty.
