2.3 Features

This compact, rugged ISDN S/T interface line test set provides many essential diagnostic functions. It’s easy to use, too, requiring very little knowledge about complex ISDN protocols. The Test Set:

Verifies physical layer (Layer 1) parameters.

Checks for D Channel Access.

Is lightweight and hand-held.

Derives power from a 9-volt battery.

Includes easy-to-use, Pass/Fail LEDs that give instantaneous test results.

Can monitor a D Channel.

Samples every frame on the line (one every 250 microseconds).

Supports various modes of operation for fault isolation.

Can be used in either passive bus or point-to-point configurations.

Verifies DC Continuity.

Features Power Indication lamps that indicate battery presence and polarity.

Generates a 4-KHz test tone.

Includes a speaker that allows audio monitoring of line activity.
