Installing the GPS receiver for PTP-SYNC
If the chosen TDD synchronization method requires a GPS timing reference source
(see TDD synchronization configuration options on
page 2-12), then a GPS receiver
must be installed. Motorola recommends that the Trimble GPS receiver should be
used. This section describes the installation procedure for the Trimble GPS receiver.
CAUTION
Prior to power-up of equipment, ensure that all cables are connected to the
correct interfaces of the PTP-SYNC unit and the GPS receiver module.
Failure to do so may result in damage to the equipment.
Recommended kit
Trimble GPS receiver
One Trimble GPS receiver is required.
Cables and connectors
The drop cable connecting the GPS receiver to the LPU must be of the supported
Superior Essex cable type. The drop cable must have a Trimble 12-pin connector at the
GPS end, and an RJ45 connector and gland at the LPU end. For more information,
refer to Outdoor connections on
page 1-15.
LPU
One LPU kit (Figure 2-10) is required.
