com GENERAL DESCRIPTION The DS26522 is a dual-channel framer and line interface unit (LIU) combination for T1, E1, and J1 applications.
Each channel is independently configurable, supporting both long-haul and short-haul lines.
FEATURES Complete T1, E1, or J1 Long-Haul/Short-Haul Transceiver (LIU plus Framer) Internal Software-Selectable Transmit- and Receive-Side Termination for 100Ω T1 Twisted Pair, 110Ω J1 Twisted Pair, 120Ω E1 Twisted Pair, and 75Ω E1 Coaxial Applications Crystal-Less Jitter Attenuator can be Selected for Transmit or Receive Path; Jitter Attenuator Meets ETS CTR 12/13, ITU-T G.
736, G.
742, G.
823, and AT&T Pub 62411 External Master Clock can be Multiple of 2.
048MHz or 1.
544MHz for T1/J1 or E1 Operation; This Clock is Internally Adapted for T1 or E1 Usage in the Host Mode Receive-Signal Level Indication from -2.
5dB to -36dB in T1 Mode and -2.
5dB to -44dB in E1 Mode in Approximate 2.
5dB Increments Transmit Open- and Short-Circuit Detection LIU LOS in Accordance with G.
