XRT86VL38
OCTAL T1/E1/J1 FRAMER/LIU COMBO - T1 REGISTER DESCRIPTION
JANUARY 2007
REV. V1.2.0
GENERAL DESCRIPTION
The XRT86VL38 is an eight-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 XRT86VL38 provides
protection from power failures and hot swapping.
The XRT86VL38 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 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 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
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 E1/J1 frames.
The XRT86VL38 fully meets all of the latest E1/J1
specifications:
ANSI E1.107-1988, ANSI E1.403-
1995, ANSI E1.231-1993, ANSI 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.
