Hub installation & commissioning

Setup the Hub Power and RF Connection

)Install a power passing tap at the desired hub location on the cable plant and verify that the

AC power level, the downstream RF signal power level, and the downstream modulation

error rate (MER) meets ARCXtend requirements as listed below:

1. Verify that the input power is between 50 Vac and 110 Vac nominal.

2. Verify that the input downstream RF signal level is between 0 dBmV and +30 dBmV.

3. Verify that the downstream modulation error ratio (MER) going into the hub is within the

budgeted range for this link. In general a minimum MER of approximately 35 dB is

required for 256 QAM operation and 31 dB is required for 64 QAM operation.

Secure the Hub to the Strand

)Using the antenna pattern decals located on the top and side of the hub, align the hub

antenna in the approximate direction of customer site(s). Install as shown in Figure 4-1 per

the steps provided below using a 7/16” combination or socket wrench. It is recommended

that the hub be located on the strand as close as possible to the utility pole to minimize

swaying in windy conditions.

1. Attach the bracket to the messenger strand with the hanger bolts at A and B. Tighten

the hanger bolts lightly. If the existing cable bundle lashed below the messenger strand
