ETECTION
When 
E
NABLED
, the receiver detects the CRC-4 checksum bits in the outgoing E1 data stream and checks 
the received signal for errors.

IGNALING
Configures the framing format for the E1 link. The TRACER transports E1 data across the link (as long as 
the E1 signal is properly timed). Configure the framing format (using the 
S
IGNALING
 menu) to enable the 
TRACER to monitor incoming framing error events and indicate problems with the attached metallic 
service. The TRACER supports 
M
ULTIFRAMED
 (also known as CAS), 
U
NFRAMED
 (all data stream with no 
framing sequence bits), and 
F
RAMED
 (also known as CCS). The default value is 
M
ULTIFRAMED
.

ODE
Sets the line coding for the E1 link. The TRACER supports high-density bipolar 3 substitution (
HDB3
) and 
alternate mark inversion (
AMI
) 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.

Activates a loopback at the local TRACER E1 framer towards the remote end of the wireless link (see 
Figure 14). Use the local 
L
INK
 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.
