GENERAL DESCRIPTION  
FEATURES  
ꢀ
Complete T1, E1, or J1 Long-Haul/Short-Haul  
Transceiver (LIU plus Framer)  
The DS26521 is a single-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.  
ꢀ
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  
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  
Routers  
Channel Service Units (CSUs)  
Data Service Units (DSUs)  
Muxes  
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  
Switches  
Channel Banks  
T1/E1 Test Equipment
