If input errors have not increased, the local hardware (cable, router interface card) is probably in good condition. An increment in B3 errors points to a corrupt SPE or payload portion. Please try the request again. Identify the Error Event Based on the type of port adapter used, Cisco IOS Software commands display T3 error events. http://back2cloud.com/parity-error/parity-check-parity-error-system-halted.php
The meaning of PES abbreviation is "Parity Error Seconds" What is PES abbreviation? This parity byte is known as BIP-8, which is an abbreviation for bit interleaved parity.

UAS Unavailable Seconds (UAS) are calculated by counting the number of seconds that the interface is unavailable. Remove the loopback cable from the interface, and plug the T3 line back into the port. Enter the show interfaces serial command. The reason is that the reported BIP errors vary depending on where the code violation or bit flip actually occurs.
The second bit of the BIP-8 field is used exactly the same way, except that this bit performs a check on the second bits of each octet, and so on. All of the devices used in this document started with a cleared (default) configuration. Set a Hard Cable Loopback on BNC In order to set a hard plug loopback, you need a 75 ohms coaxial cable with male BNC connectors at each end. Check and clean these devices also.
Here is a table that appears in the Cisco 10000 Series ESR Troubleshooting Guide.

B2 Line overhead and synchronous payload envelope (SPE) (including path overhead and payload), before scrambling. There is considerably less chance of an even-numbered error that eludes the B2 parity calculation. Unavailable Secs (UAS): The number of one-second intervals in which the controller was down. If a router passes a hard plug loopback test, the problem lies elsewhere on the T3 line.
To prepare for the BERT on a T1 line, clear the interface counters using the clear counters command. http://www.cisco.com/c/en/us/support/docs/wan/t1-e1-t3-e3/61240-t3erevts-61240.html When Do Particular BIP Errors Occur? Verify the Hard Plug Loopback Based on the type of port adapter used, you must verify the hard loopback throuh extended pings (for PA-T3), or a T1 Bit Error Rate Test However, SF-BER and SD-BER feed into the automatic protection switching (APS) machine, and can lead to a protection switch (if you have configured APS).
The reason is that the BIP value carried in the current frame is the value calculated on the previous frame. navigate here If your network is live, make sure that you understand the potential impact of any command. When you contact the Cisco Technical Assistance Center (TAC): Collect output from the show running-config command. PSES A P-bit Severely Errored Second (PSES) is a second with: 44 or more PCVs, or One or more Out of Frame defects, or A detected incoming AIS.
A router common reports TC alarms when the router declares a path-level or line-level alarm. The DS3 interface is said to be unavailable from the onset of 10 contiguous PSESs, or the onset of the condition leading to a failure. Aug 7 04:32:41 BST: %SONET-4-ALARM: POS4/6: B1 BER exceeds threshold, TC alarm declared Aug 7 04:32:41 BST: %SONET-4-ALARM: POS4/6: B2 BER exceeds threshold, TC alarm declared Aug 7 04:32:41 BST: %SONET-4-ALARM: Check This Out In all cases, test the quality of the cables and connections.
BIP-8 Bytes in SONET Overhead SONET is a protocol that uses an architecture of layers: section, line and path. After the BERT is completed, examine the show controllers T3 command output, and determine whether: The number of bits received corresponds with the number of bits sent on the T1 line Use the show running-config command to check whether the interface has a unique IP address.
ADMs and regenerators do not terminate the path overhead and must not report B3 errors. When prompted for a destination filename, press ENTER. Prerequisites Requirements Cisco recommends that you have knowledge of these topics: SONET (Synchronous Optical NETwork). Swap the cables.
C-bit Errored Secs: Number of seconds with one or more CCV, one or more Out-of-Frame defects, or a detected incoming AIS. CES is not incremented when UASs are counted. Randhawa,Stephen HardyNo preview available - 2010Common terms and phrasesaccess control policies Alarm Indication Signal assumed ATM cells B-ISDN bandwidth bandwidth optimization bit error rate bit rate call admission control call arrival this contact form CES A C-bit Errored Second (CES) is a second with: One or more CCVs, or One or more Out of Frame defects, or A detected incoming AIS.
Differences indicate the occurrence of section-level bit errors. Web. 23 October 2016.
C-bit Coding Violation (CCV): The number of coding violations reported through the C-bits. LCV Line Coding Violation (LCV) is a count of both BiPolar Violation (BPV) error events and Excessive Zeros (EXZ) error events occurring over the accumulation period. Please refer to the end of this passage. Clear the interface counters.

This information should not be considered complete, up to date, and is not intended to be used in place of a visit, consultation, or advice of a legal, medical, or any A BIP error can occur anywhere in the frame. Insert an external loopback cable into the port.
If your network is live, make sure that you understand the potential impact of any command. Prerequisites Requirements There are no specific requirements for this document. CSE All Acronyms. Data in current interval (81 seconds elapsed): 0 Line Code Violations, 0 P-bit Coding Violation 0 C-bit Coding Violation 0 P-bit Err Secs, 0 P-bit Severely Err Secs 0 Severely Err
If the serial interface does not have an IP address, obtain a unique address, and assign it to the interface with a subnet mask of 255.255.255.0. Background Information When the number of BIP errors crosses a threshold that you can configure, the router reports log messages similar to this: Feb 22 08:47:16.793: %LINEPROTO-5-UPDOWN: Line protocol on Interface CSES A C-bit Severely Errored Second (CSES) is a second with: 44 or more CCVs, or One or more Out of Frame defects, or A detected incoming AIS. In other words, parity bytes monitor and detect errors over different parts of a SONET frame.
