8-CHANNEL T1/E1/J1 FRAMER/LIU COMBO - T1 REGISTER DESCRIPTION

2011 REV. 1.0.3

GENERAL DESCRIPTION

The XRT86VX38 is an eight-channel 1.544 Mbit/s or

2.048 Mbit/s DS1/E1/J1 framer and Long-haul/Short-

hual LIU integrated solution featuring R3technology

(Relayless, Reconfigurable, Redundancy) and BITS

Timing element. The physical interface is optimized

with internal impedance, and with the patented pad

structure, the XRT86VX38 provides protection from

power failures and hot swapping.

The XRT86VX38 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 XRT86VX38 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.
