Single/Dual/Triple/Quad DS3/E3/STS-1 LIUs

The DS3151 (single), DS3152 (dual), DS3153 (triple), and DS3154 (quad) line interface units (LIUs) perform the functions necessary for interfacing at the physical layer to DS3, E3, or STS-1 lines. Each LIU has independent receive and transmit paths and a built-in jitter attenuator.

Applications

* Access Concentrators * ATM and Frame Relay Equipment * Digital Cross-Connects * DSLAMs * PBXs * Routers/Switches * SONET/SDH and PDH Multiplexers * Test Equipment

* Single, Dual, Triple, or Quad Integrated Transmitter, Receiver, and Jitter Attenuators for DS3, E3, and STS-1
