com GENERAL DESCRIPTION The DS26518 is a single-chip 8-port framer and line interface unit (LIU) combination for T1, E1, and J1 applications.
Each port is independently configurable, supporting both long-haul and short-haul lines.
The 8-port SCT is software compatible with the DS26519 and nearly software compatible with the DS26528 and its derivatives.
FEATURES Eight Complete T1, E1, or J1 Long-Haul/ Short-Haul Transceivers (LIU Plus Framer) Independent T1, E1, or J1 Selections for Each Transceiver Fully Internal Impedance Match, No External Resistor Software-Selectable Transmit- and ReceiveSide Termination for 100Ω T1 Twisted Pair, 110Ω J1 Twisted Pair, 120Ω E1 Twisted Pair, and 75Ω E1 Coaxial Applications Hitless Protection Switching Crystal-Less Jitter Attenuators Can Be Selected for Transmit or Receive Path; Jitter Attenuator Meets ETS CTR 12/13, ITU-T G.
