XRT86VL30
SINGLE T1/E1/J1 FRAMER/LIU COMBO - T1 REGISTER DESCRIPTION
2009
REV. 1.0.1
GENERAL DESCRIPTION
The XRT86VL30 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,
Reconfigurable,
Redundancy).
The
physical
interface is optimized with internal impedance, and
with the patented pad structure, the XRT86VL30
provides protection from power failures and hot
swapping.
The XRT86VL30 contains an integrated DS1/E1/J1
framer and LIU which provides DS1/E1/J1 framing
and error accumulation in accordance with ANSI/
ITU_T specifications. The 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.
The Framer block contains its own 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 access to the Data Link
bits of the inbound T1/E1/J1 frames.
The XRT86VL30 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.
