XRT86VL34
QUAD T1/E1/J1 FRAMER/LIU COMBO - T1 REGISTER DESCRIPTION
APRIL 2011
REV. V1.2.1
GENERAL DESCRIPTION
The XRT86VL34 is a four-channel 1.544 Mbit/s or
2.048 Mbit/s DS1/E1/J1 framer and LIU integrated
solution
featuring
R3
technology
(Relayless,
Reconfigurable,
Redundancy).
The
physical
interface is optimized with internal impedance, and
with the patented pad structure, the XRT86VL34
provides protection from power failures and hot
swapping.
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.
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
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.
The XRT86VL34 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,
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.
