Sets the line coding for the E1 link. The TRACER 64x0 supports high-density bipolar 3 substitution 
(

) and alternate mark inversion (

) line coding. HDB3 coding does not allow more than three 

consecutive zeros in a transmitted bit stream and is the standard coding method on public networks. 

Controls the loop status of the E1 link. Activates/deactivates loopback conditions for testing purposes.

Defines the E1 link as normal data transport mode; there are no active loopbacks.

Activates a loopback at the local TRACER 64x0 E1 framer towards the remote end of the wireless link 
(see Figure 15). Use the local 

 loopback to loop the data transmitted from the remote end of the link 

back across the radio link to the remote end of the link. This loopback tests the integrity of the radio link 
and all the associated digital and RF hardware.

Activates a loopback at the remote TRACER 64x0 E1 framer towards the local end of the wireless link 
(see Figure 16). Use the remote 

 loopback to loop the data transmitted from the local end of the link 

across the radio link to the local end of the link. This loopback tests the integrity of the radio link and all 
the associated digital and RF hardware.

Activates a loopback at the local TRACER 64x0 E1 framer towards the locally connected E1 equipment 
(see Figure 17). Use the local 

 loopback to test data path integrity from the local TRACER 64x0 unit to 

the connected E1 equipment.
