the external termination mode.
Table 11 summarizes the transmit terminations.
REDUNDANCY APPLICATIONS
Telecommunication system design requires signal integrity and reliability. When a T1/E1 primary line card has
a failure, it must be swapped with a backup line card while maintaining connectivity to a backplane without
losing data. System designers can achieve this by implementing common redundancy schemes with the
XRT83SL38 Line Interface Unit (LIU). The XRT83SL38 offers features that are tailored to redundancy
applications while reducing the number of components and providing system designers with solid reference
designs. These features allow system designers to implement redundancy applications that ensure reliability.
The Internal Impedance mode eliminates the need for external relays when using the 1:1 and 1+1 redundancy
schemes.
