Product Details
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.
Applications
- Channel Banks
- Channel Service Units (CSUs)
- Data Service Units (DSUs)
- Muxes
- Routers
- Switches
- T1/E1 Test Equipment
