Hardware overview
The main hardware components of the PTP 670 are as follows:
• Outdoor unit (ODU): The ODU is a self-contained transceiver unit that houses both radio
and networking electronics. The PTP 670 ODU is supplied in two configurations:
o
A PTP 670 Integrated ODU attached to a 23 dBi flat plate antenna
o
A PTP 670 Connectorized ODU intended to work with separately mounted external
antennas.
•
The ODU is supplied in the following frequency variants:
o
4.8 to 5.9 GHz
o
4.9 to 6.05 GHz
•
The ODU is supplied in the following regional variants:
o
FCC, intended for deployment in the USA
o
European Union (EU), intended for deployment in countries of the European Union or
other countries following ETSI regulations
o
IC, intended for deployment in Canada under the rules of ISEDC.
o
Mexico, intended for use in Mexico
o
RoW, intended for deployment in countries other than USA, Canada and EU countries.
•
Power supply unit (PSU): PTP 670 provides three options for PSUs:
o
The AC Power Injector 56V is suitable for powering a single ODU without an auxiliary
device. The AC Power Injector 56V is not approved for use with the 4.8 GHz to 5.9 GHz
frequency variants of PTP 670.
o
The AC+DC Power Injector 56V is required when powering a single PTP 670 ODU from
a DC supply, when powering an auxiliary device, when using PTP-SYNC, or when the
PSU is needed to operate at extreme temperatures.
o
The Cluster Management Module (CMM5) is a modular system consisting of power
injectors, power supplies, a controller and a GPS receiver. Each Power and Sync
Injector can power up to four ODUs. CMM5 also distributes a synchronization signal
from a Universal GPS (UGPS) receiver to the ODUs.
•
Antennas and antenna cabling: Connectorized ODUs require external antennas connected
using RF cable.
•
PTP SYNC unit (optional): The PTP SYNC unit can be used with the AC+DC Enhanced
Power Injector 56V to provide TDD synchronization at a TDD Master ODU. PTP-SYNC must
be used with the AC+DC Enhanced Power Injector 56V.
•
GPS receivers: PTP 670 supports two different GPS receivers for network-wide TDD
synchronization. The Trimble Acutime™GG GPS receiver is used with PTP-SYNC. The
Universal GPS (UGPS) receiver is used with CMM5.
•
Network Indoor Unit (NIDU) (optional): The NIDU allows up to eight TDM channels (E1 or
T1) to be bridged over a PTP 670 link.
•
Ethernet cabling: All configurations require a copper Ethernet Cat5e connection from the
ODU (PSU port) to the PSU. Advanced configurations may also require one or both of the
following:
o
A copper or optical Ethernet connection from the ODU (SFP port) to network
terminating equipment or another device.
