This unit

The Fluke 635A QuickBERT-T1 is a portable, battery-powered handheld test set engineered for T1 line verification, diagnostics, and performance validation. Field technicians and network engineers use this instrument to characterize T1 circuits, measure key performance parameters, and isolate transmission faults. The device performs Bit Error Rate Testing (BERT), fractional T1 BERT (Nx56 and Nx64), and HDSL loop code transmission with automatic synchronization to framing type, line coding, and BERT patterns.

Technical Specifications

Bit Error Rate Testing (BERT) on full and fractional T1 circuits (Nx56 and Nx64)

HDSL loop code transmission

Transmits eleven standard BERT patterns plus 64-bit user-defined pattern

"Through" mode for retransmitting incoming patterns
