Revision 1.1  
SXT6251  
21 E1 SDH Mapper  
General Description  
Features  
The SXT6251 21E1 Mapper performs asynchronous map-  
ping and demapping of 21 E1 PDH signals into SDH. The  
PDH side interfaces with E1 LIUs and framers via NRZ  
Clock & Data, while the SDH side uses a standard Telecom  
bus interface. Further processing by the companion  
SXT6051 Overhead Terminator chip creates the final  
STM-0 or STM-1 signal. One mapper provides complete  
processing of 21 E1s in STM-0, while three mappers can  
process 63 E1s in STM-1.  
• Maps and Demaps 21 E1 signals between PDH and  
SDH networks via VC-12 asynchronous mapping.  
• Multiplexes the 21 VC-12 signals into seven inter-  
leaved TUG-2 structures for STM-0 or a TUG-3  
structure for STM-1 applications.  
• Configurable as a flexible Add/Drop Multiplexer for  
up to 21 E1 tributaries, with each E1 I/O port assign-  
able to any TU time slot within an AU-3 or TUG-3.  
• Performs VC-12 path overhead processing for all 21  
VC-12s, including V5, J2 Path Trace, and K4  
Enhanced RDI.  
The SXT6251 is compliant with the latest releases of ITU-  
T G.703 and G.707. It provides all the alarm and control  
features to easily implement the multiplexer specified in  
ITU-T G.783.  
• Records TU pointer alarms (TU-AIS, TU-LOP), BIP-  
2 and REI error counts, TIM and PLM alarms, and all  
other V5 POH alarms for all 21 tributaries.  
• NRZ Data and Clock interface for E1 tributary access.  
Applications  
• Microprocessor/SEMF interface to set Signal Label,  
J2 Path Trace, access alarms and counters  
• 21 or 63 E1 Terminal or ADM SDH Multiplexer  
• Digital Cross Connect System  
• Low power CMOS technology with 3.3V core and 5V  
I/O, available in PQFP-208 package.  
• Digital Loop Carrier Systems (NGDLC)  
• Microwave Radio Systems  
• IEEE 1149.1 (JTAG) support.
