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

4-0

EQC[4:0]

R/W

00000

Equalizer Control [4:0]:

 

These bits are used to control the transmit pulse shaping, transmit 
line build-out (LBO) and receive sensitivity level. 

The Transmit Pulse Shape can be controlled by adjusting the Trans-
mit Line Build-Out Settings for different cable length in T1 mode. 
Transmit pulse shape can also be controlled by using the Arbitrary 
mode, where users can specify the amplitude of the pulse shape by 
using the 8 Arbitrary Pulse Segments provided in the LIU registers 
(0xNF08-0xNF0F), where n is the channel number.

The XRT86VX38 device supports both long haul and short haul 
applications which can also be selected using the EQC[4:0] bits.   

Table 162

.presents the corresponding Transmit Line Build Out and 

Receive Sensitivity settings using different combinations of these 
five EQC[4:0] bits.
