These units are compact, handheld, fully-featured T1 test sets designed to thoroughly verify the performance parameter of a T1 facility. Design Highlights The QuickBERT-T1 and QuickCHECK-T1 are designed to allow users to easily analyze and correct the common problems arising in T1 networks. Experienced and inexperienced users alike can determine the integrity, configuration parameters, and general performance of a T1 circuit when using these units. Features include the following. · Is handheld and battery powered · Transmits all standard T1 bit error rate test (BERT) patterns and loop codes (QuickBERT-T1 only) · Transmits HDSL loop codes (QuickBERT-T1 only) · Has the ability to insert logic, BPV, and frame bit errors (QuickBERT-T1 only) · Performs BERT and Fractional T1 BERT (Nx56 and Nx64) · Captures and displays DTMF digits · Measures DS1 frequency, level, and clock slips · Displays standard T1 alarms · Displays major T1 performance parameters · Displays AMI or B8ZS line coding · Measures DS0 level and frequency · Monitors voice using internal speaker (or headset) · Displays DS0 data and signaling bits · Automatically synchronizes to and displays the T1 framing type, line coding, and BERT pattern
