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.
