Low-Pass Filter Specifications

Filter Shelf

Low-Pass filters are used with the BitStorm 1900 in EtherLoop applica-

tions where voice service is required. The low-pass filter cards separate

out-of-voiceband signals from the voiceband traffic between the Bit-

Storm modems and the external voice facility equipment. The Low-

Pass Filter Shelf contains one filter card for each modem card.

The filter shelf connects to the distribution frame, designed to minimize

signal interference and facilitate broadband connectivity by isolating

Digital Service Units (DSUs) from the Private Branch Exchange

(PBX). Refer to Figure 1-19 on page 46 for Filter Shelf Specifications.

Filter 66-Block

The Filter 66-Block provides the same function as the filter shelf, how-

ever, it is a space saving and economical alternative to the filter shelf

for large enterprise installations. Refer to Figure 1-19 on page 46 for

Filter 66-Block Specifications.
