GENERAL DESCRIPTION
The DS26528 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.
APPLICATIONS

Octal T1/E1/J1 Transceiver
FEATURES
§ Eight Complete T1, E1, or J1 Long-Haul/Short-
Haul Transceivers (LIU plus Framer)
§ Independent T1, E1, or J1 Selections for Each
Transceiver
§ Internal Software-Selectable Transmit- and
Receive-Side Termination for 100W T1 Twisted
Pair, 110W J1 Twisted Pair, 120W E1 Twisted
Pair, and 75W E1 Coaxial Applications
§ Crystal-Less Jitter Attenuators can be Selected
for Transmit or Receive Path. The Jitter
Attenuator meets ETSI CTR 12/13, ITU 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.775, ETSI
300233, and T1.231
§ Transmit Synchronizer
§ Flexible Signaling Extraction and Insertion Using
Either the System Interface or Microprocessor
Port
§ Alarm Detection and Insertion
§ T1 Framing Formats of D4, SLC-96, and ESF
§ J1 Support
§ E1 G.704 and CRC-4 Multiframe
§ T1 to E1 Conversion
Features continued in Section 2.
