8-Port T1/E1/J1 Transceiver
Latest Generation of SCTs with the Industry's Highest Port Count
|
Status
Active: In Production.
Description
The DS26518 is an 8-port framer and line interface unit (LIU) combination for T1, E1, J1 applications. Each port is independently configurable, supporting both long-haul and short-haul lines. The DS26518 Single-Chip Transceiver (SCT) is software and pinout compatible with the 4-port DS26514. It is nearly software compatible with the DS26528 and its derivatives.
