| e BD21140 and BD21141 are compact, feature packed T1 handheld test sets that can be used for in-service or out-of-service testing. Designed to evaluate the integrity, configuration, and performance of a T1 facility, these units locate complete failures in a transmission line or a piece of equipment. They are ideal for verifying network performance, isolating faulty DTE or DCE and determining faulty transmission channels. Complete end-to-end testing may be performed at any point in the span by utilizing industry standard loop codes. Finally, these units may be used at the DSX-1 cross connect jack panel, bridged onto the span or serve as a substitute for transmission equipment for real world testing. |
