(PTP 600) and 500-04-00 (PTP 500). TDD synchronization (and thus PTP-SYNC) is not supported with PTP 300. CAUTION Do not install the PTP-SYNC unit in a domestic (home) environment as it is a Class ‘A’ product. In a domestic (home) environment, it may cause radio frequency (RF) interference in other appliances.
Grounding PTP-SYNC In order to meet the safety requirements for deployment in Australia and New Zealand (AS/NZS 60950-1), the PTP-SYNC unit, if deployed, must be grounded to a Protective Ground in accordance with Local Electrical Regulations. Powering down before servicing Always power down and unplug the equipment before servicing.
Motorola part number WB3665. The kit contains: 1 x PTP-SYNC unit; 1 x M4 pan screw; 2 x M4 washers; 2 x M3 (6mm) torx drive screws; 1 x lug for unit ground (cable not supplied); 1 x Cat5e cable (length 1 meter).
Unit (LPU) kit CAUTION Always use Cat5e cable that is gel-filled and shielded with copper-plated steel. Alternative types of drop cable are not supported by Motorola. Superior Essex BBDGe can be bought from Motorola with part numbers listed above. NOTE The connector, crimp tool and die set listed above are specific to Superior Essex BBDGe cable.

PTP-SYNC Installation Guide Grounding and lightning protection If a GPS receiver is the selected timing reference source, then the installation must be protected as described in this section. WARNING Electro-magnetic discharge (lightning) damage is not covered under warranty. The recommendations in this document, when followed correctly, give the user the best protection from the harmful effects of EMD.
Basic requirements The following basic protection requirements must be implemented: • The equipment (GPS receiver for PTP-SYNC) must be in ‘Zone B’. • A lightning protection unit (LPU) must be installed within 600 mm (24 in) of the point at which the drop cable enters the building or equipment room.
• Approved bonding techniques must be used for the connection of dissimilar metals. GPS receiver location requirements The GPS receiver for PTP-SYNC must be mounted at a location that meets both the general protection requirements and the following requirements: •...
PTP-SYNC Installation Guide 3. Grounding and lightning protection Mounting the GPS receiver on the equipment building If mounting the GPS receiver for PTP-SYNC on the equipment building, select a position on the wall that meets the following requirements: • It must be below the roof height of the equipment building or below the height of any roof-mounted equipment (such as air conditioning plant).
PTP-SYNC Installation Guide 3. Grounding and lightning protection Mounting the GPS receiver on a metal tower or mast For mast or tower installations, the following additional requirements must be met: • The equipment must not be mounted any higher than is necessary to receive an adequate signal from four GPS satellites.
PTP-SYNC Installation Guide 3. Grounding and lightning protection Maximum cable lengths The maximum permitted length of the GPS drop cable (GPS receiver to PTP-SYNC) is 100 m (330 ft). The maximum permitted lengths of the main ODU to network drop cable are:...
Use the single link configuration where a site contains only one TDD master ODU. Each link requires one PTP-SYNC unit connected to the master ODU and one compatible GPS receiver. The GPS receiver and LPU can be replaced by an alternative compatible 1 Hz timing reference.
TDD master ODUs. Each link requires one PTP-SYNC unit. Each site requires one compatible GPS receiver. Collocated PTP-SYNC units are connected together in a daisy-chain. Between two and ten PTP- SYNCs may be chained in this way.
Install the PTP-SYNC unit in the equipment building, either in a rack or on a wall: • Rack mounting: If the PTP-SYNC is to be in a rack, fix it to the rack mount using the M3 screws from the rack mount installation kit : •...
PTP-SYNC Installation Guide 5. Installing PTP-SYNC Connecting up PTP-SYNC To connect the PTP-SYNC to the PIDU, ODU, GPS receiver (if fitted), and LPU (if fitted), proceed as follows: Disconnect the power supply from the PIDU. If using GPS, connect the cable from the GPS unit to the GPS/SYNC IN port.
System using a GPS receiver module - Ensure that there is a cable connection between the PTP-SYNC ‘GPS/SYNC IN’ interface and the LPU, also that there is a cable connection between the LPU and the GPS receiver module. Check that the GPS receiver module has an uninterrupted view of the sky.

The ‘ODU’ LED does not illuminate within 90 seconds of power- This probably indicates that there is no communication between PTP-SYNC and ODU. Ensure that the PTP-SYNC ‘ODU OUT’ interface is connected to the ODU (and LPUs if installed) via the drop cable.
