XRT86VL34  
QUAD T1/E1/J1 FRAMER/LIU COMBO - T1 REGISTER DESCRIPTION  
APRIL 2011  
REV.V1.2.1  
payload content of Receive LAPD Message frames  
from the incoming T1/E1/J1 data stream and write the  
contents into the Receive HDLC buffers. Each framer  
also contains a Transmit and Overhead Data Input  
port, which permits Data Link Terminal Equipment  
direct access to the outbound T1/E1/J1 frames.  
Likewise, a Receive Overhead output data port  
permits Data Link Terminal Equipment direct access  
to the Data Link bits of the inbound T1/E1/J1 frames.  
GENERAL DESCRIPTION  
The XRT86VL34 is a four-channel 1.544 Mbit/s or  
2.048 Mbit/s DS1/E1/J1 framer and LIU integrated  
3
solution featuring  
R
technology (Relayless,  
The physical  
Reconfigurable, Redundancy).  
interface is optimized with internal impedance, and  
with the patented pad structure, the XRT86VL34  
provides protection from power failures and hot  
swapping.  
The XRT86VL34 fully meets all of the latest T1/E1/J1  
specifications:  
ANSI T1/E1.107-1988, ANSI T1/  
The XRT86VL34 contains an integrated DS1/E1/J1  
framer and LIU which provide DS1/E1/J1 framing and  
error accumulation in accordance with ANSI/ITU_T  
specifications. Each framer has its own framing  
synchronizer and transmit-receive slip buffers. The  
slip buffers can be independently enabled or disabled  
as required and can be configured to frame to the  
common DS1/E1/J1 signal formats.  
E1.403-1995, ANSI T1/E1.231-1993, ANSI T1/  
E1.408-1990, AT&T TR 62411 (12-90) TR54016, and  
ITU G-703, G.704, G706 and G.733, AT&T Pub.  
43801, and ETS 300 011, 300 233, JT G.703, JT  
G.704, JT G706, I.431. Extensive test and diagnostic  
functions include Loop-backs, Boundary scan,  
Pseudo Random bit sequence (PRBS) test pattern  
generation, Performance Monitor, Bit Error Rate  
(BER) meter, forced error insertion, and LAPD  
unchannelized data payload processing according to  
ITU-T standard Q.921.  
Each Framer block contains its own Transmit and  
Receive T1/E1/J1 Framing function. There are 3  
Transmit HDLC controllers per channel which  
encapsulate contents of the Transmit HDLC buffers  
into LAPD Message frames. There are 3 Receive  
HDLC controllers per channel which extract the
