T1/E1 and T3/E3 Clear and Show Commands
XSR CLI Reference Guide 2-79
FEAC code received Displays the last 4 FEAC codes or commands that were received. Applicable
for C ‐ bit parity framing only, per ANSI T1.105 ‐ 1995. This field are intended for
T3 line debugging by carrier personal.
Values (the last four codes are just displayed, subsequent codes will overwrite
current ones) listed are as follows:
• DS3 Eqpt. Failure (SA)
• DS3 LOS
• DS3 Out ‐ of ‐ Frame
• DS3 AIS Received
• DS3 IDLE Received
• DS3 Eqpt. Failure (NSA)
• Common Eqpt. Failure (NSA)
• Multiple DS1 LOS
• DS1 Eqpt. Failure (SA)
• Single DS1 LOS
• DS1 Eqpt. Failure (NSA)
• No code is being received
Command values are as follows:
• Loopback Activate
• Loopback Deactivate
• DS3 Line
• DS1 Line 1 to 28 (displayed but not acted upon)
• DS1 Line All (displayed but not acted upon)
Framing is Framing type on the controller:
• C ‐ BIT Parity
• M13
• G.751
• Bypass
Line Code is Line coding format on the controller: B3ZS
Clock Source is Clock source on the controller: Internal or Line .
Line Code Violations (Valid for C ‐
bit, M13, g751 & bypass)
A count of both Bipolar Violations (BPVs) and Excessive Zeros (EXZs)
occurring over the accumulation period. An EXZ increments the LCV by one
regardless of the zero string’s length.
P ‐ bit Coding Violation (Valid for
C ‐ bit & M13)
For all DS3 applications, a PCV error event is a P ‐ bit parity error event. A P ‐ bit
parity error event is the occurrence of a received P ‐ bit code on the DS3 M ‐
frame that is not identical to the corresponding locally calculated code.
C ‐ bit Coding Violation (Valid for
C ‐ bit)
For C ‐ bit parity applications, the CCV is the sum of coding violations reported
via the C ‐ bits. For C ‐ bit parity, it is the sum of CP ‐ bit parity errors occurring
during the accumulation interval.
P ‐ bit Err Secs (Valid for C ‐ bit &
M13)
PES is a second with one or more PCVs, one or more Out ‐ of ‐ Frame defects, or
a detected incoming AIS. This gauge is not incremented when unavailable
seconds are counted.
