ImageStream WAN Monitoring Tapper

E3 Tap

Passive E3 Tap

DS3 and E3 Taps

ImageStream offers both DS3 and E3 data circuit taps for passive monitoring applications. As passive monitoring devices, the DS3 and E3 taps do not interrupt the data circuit when the monitor card is disconnected from the tap.

The DS3 and E3 taps each provide four 75 ohm coaxial BNC connectors that are used to connect the line and pass through the full duplex data traffic. The tap also provides a DB15 interface for connecting the tap cable to the monitoring card.

The DS3 and E3 taps present a high-impedance interface to each of the two data circuit signals. The tap acts as a repeater that retransmits each input signal back out through the tap's output connection. The tap can drive this output signal across coaxial cabling over distances of up to 450 feet (137 meters).

The tap cable carries data signals from the tap's DB15 connector to the monitor card, and it carries power from the monitor card to the tap. The length of the tap cable must be 15 feet (4.5 meters) or less.
