Overview of the PTP 700 Series
This section introduces the key features, typical uses, product variants and components of the
PTP 700 series.
Purpose
Cambium PTP 700 Series Bridge products are designed for Ethernet bridging over point-to-
point microwave links in licensed, unlicensed and lightly-licensed frequency bands between
4400 MHz and 5875 MHz. Users must ensure that the PTP 700 Series complies with local
operating regulations.
The PTP 700 Series acts as a transparent bridge between two segments of the operator’s
network. In this sense, it can be treated as a virtual wired connection between two points. The
PTP 700 Series
forwards 802.3 Ethernet frames destined for the other part of the network and
filters frames it does not need to forward. The system is transparent to higher-level protocols
such as VLANs and Spanning Tree.
Key features
The PTP 700 is a high performance wireless bridge for Ethernet traffic with a maximum
throughput of 450 Mbps. It is capable of operating in line-of-sight (LOS), near-LOS and non-
LOS propagation condition. Its maximum LOS range is 200 km. The PTP 700 operates in
licensed, unlicensed and lightly-licensed frequency bands between 4400 MHz and 5875 MHz. It
has a very high spectral efficiency of 10 bps/Hz and supports a channel bandwidth of up to
45 MHz. The PTP 700 Connectorized ODU is designed for use with an external antenna. The
PTP 700 Connectorized+Integrated ODU can be used with an external antenna or with an
integrated 21 dBi flat plate antenna.
The wireless link is TDD based and supports both symmetric and asymmetric TDD
configurations.
From an Ethernet point-of-view, the PTP 700 wireless link is a transparent Layer 2 bridge. It
supports up to three Gigabit Ethernet ports. Two ports support twisted pair Gigabit Ethernet.
One of them is capable of providing power via standard 802.3at PoE to an external device such
as a video surveillance camera or a wireless access point. The third port accepts either a
twisted pair or fibre GE SFP module.
The PTP 700 Series supports an optional TDM adaptor that allows E1 or T1 telecoms circuits to
be bridged over the wireless link.
The PTP 700 Series has extensive quality of service (QoS) classification capability and supports
up to eight levels of queues. Management of the unit may be via the same interface as the
bridged traffic (in-band management) or on a separate port (out-of-band local or remote
management).
PTP 700 supports both synchronous Ethernet and operation as an IEEE 1588-2008 transparent
clock.
