CLICK HERE TO VIEW MODEL DETAILS AND SPECIFICATIONS-pdf

Features

Feature description includes 10T1 and 20T1 for comparison, please see the pdf file for more detailed descriptions

• Complete in-service or out-of-service testing
• End-to-end T1 span testing with the most common industry standard loop codes
• Model 20T1 performs BERT on one of 17 standard stress patterns and two user-definable 32-bit patterns
• Determines T1 framing and BERT patterns
• Model 20T1 transmits standard, HDSL and Smart Repeater T1 loop codes
• Intuitive, user-friendly interface
• Portable for outside plant applications

The Megger ฎ InterroGatr 10T1 and 20T1 are compact, feature packed T1 test sets that can be used for in-ser-viceor out-of-service testing. Com-plete end-to-end testing may be performed at any point in the span by utilizing industry standard Loop Codes. The units may be used at the DSX-1 cross connect jack panel, bridged onto the span or can be a sub-stitute for transmission equipment for real world testing.

InterroGatr 20T1

In addition to its lightweight, battery-operated design, features of the InterroGatr 20T1 include:

• Transmits standard, HDSL and Smart Repeater T1 loop codes.
• Operating Modes include Originate, Fractional T1, Half duplex Drop & In-sert,Test Loopback, Local Loopback,Tone Insert, BTP (Bridge Tap Testing), MPT (Multi-pattern Testing), and LoopDelay Measurement.
• Performs BERT on one of 17 stan-dard stress patterns and two user de-finable 32-bit patterns.
• Store and recall up to four pro-grams.
• Measures DS1 level and frequency in volts and dB.
• Detects timing problems, such as clock slips.
