3.3V, 16-Channel, E1/T1/J1 Short and Long-Haul Line Interface Unit

GENERAL DESCRIPTION The DS26334 is a 16-channel short/long-haul line interface unit (LIU) that supports E1/T1/J1 from a single 3.3V power supply. A single bill of material can support E1/T1/J1 that requires no external termination. Redundancy is supported through nonintrusive monitoring, optimal
