Configuration Guide

source and uses a single 10/100 BaseT Half/Full duplex connection to interface into the CMM or

appropriate network connection.

The AP Cluster has eight usable ports that may be configured to contain five main components:

• Cluster Management Module (CMM)

– GPS Receiver

– Hardened Ethernet Switch

• AP Modules (A cluster can support up to six APs)

• Surge Suppressor (A single cluster requires one surge suppressor

to protect the network connection to the CMM when the BH Module

is not used with the CMM.)

• BH Modules (Up to two modules are typically used)

• Power Source (the AP Cluster is powered by the CMM which requires

a 110 or 220 VAC or 24 VDC power source)

Subscriber Module (SM)

The SM is the subscriber termination unit or the Customer Premise Equipment (CPE). It consists

of a single module that operates with an integrated 60-degree antenna. Each SM can

communicate to a single AP Module at any given time. SM synchronization and control is

accomplished via the received AP signal. SMs are typically located outdoor and Line of Sight

(LOS) from the APs. Once the SM is initialized, it scans the Radio Frequency (RF) channels and

automatically registers with the appropriate AP. Each SM requires a Category 5 cable for its

Ethernet connection to the premise IP equipment with DC power supplied to the SM through that

same cable. The SM uses a 110 VAC power supply (ACPS110-01 or -02) or the 90V-230V

switching power supply (ACPSSW-01) and associated RJ45 connector to power the SM. The

Universal Mounting Bracket (SMMB1) is available for mounting the SM to the customer site.

One SMMB1 is required for each SM. It is recommended to use a Canopy Ethernet Surge

Protector (300SS) mounted at the Ethernet entry point on the outside wall of the premise.

Backhaul (BH) Module

The BH Module is a Point-To-Point radio that carries traffic to and from AP Clusters. A set of

Point-to-Point BH Modules can also be used as a low latency Ethernet bridge between any two

networks or between a network and a single remote computer. In the event no convenient fiber

or cable connection is available for IP connectivity to an AP Cluster, a set of BH Modules can be

used. Each BH Module (5700BHRF) communicates to another BH Module using a highly

directional antenna. The BH Module operates with a raw data bit rate of 10 Mbps with an

approximate throughput of 7+ Mbps and has a maximum range of approximately 35 miles. The

BH uplink/downlink bandwidth ratio for a single BH link is configurable by the operator (i.e. 75

percent downlink and 25 percent uplink or 50 percent uplink and 50 percent downlink – set at

timing master). When two BH pairs are configured back-to-back in a daisy chain configuration,

they each need to be configured for symmetrical load with 50 percent allocated for uplink and

downlink. Each BH Module receives its 24VDC power from a 110-power supply (ACPS110-01
