REV. P1.0.1
GENERAL DESCRIPTION
The XRT86L30 is a single channel 1.544 Mbit/s or
2.048 Mbit/s DS1/E1/J1 framer and LIU integrated
solution featuring R3 technology (Relayless, Recon-
figurable, Redundancy). The physical interface is op-
timized with internal impedance, and with the patent-
ed pad structure, the XRT86L30 provides protection
from power failures and hot swapping.
The XRT86L30 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. The framer has a 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.
The Framer block contains a Transmit and Receive
T1/E1/J1 Framing function. There are 3 Transmit
HDLC controllers which encapsulate contents of the
Transmit HDLC buffers into LAPD Message frames.
There are 3 Receive HDLC controllers which extract
the payload content of Receive LAPD Message
frames from the incoming T1/E1/J1 data stream and
write the contents into the Receive HDLC buffers.
The 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 ac-
cess to the Data Link bits of the inbound T1/E1/J1
frames.
The XRT86L30 fully meets all of the latest T1/E1/J1
specifications: ANSI T1/E1.107-1988, ANSI T1/
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, Pseu-
do Random bit sequence (PRBS) test pattern gener-
ation, Performance Monitor, Bit Error Rate (BER)
meter, forced error insertion, and LAPD unchannel-
ized data payload processing according to ITU-T
standard Q.921.
