The type of port adapter determines whether you must verify the hard loopback by means of extended pings, for the PA-E3 port adapter, or an E1 Bit Error Rate Test (BERT), for the PA-MC-E3 port adapter.
This is only for the PA-MC-E3 port adapter.

You also need to configure the clock source internal command on the E3 serial interface/controller and on all E1 controllers. Use this coaxial cable in order to connect the transmit (Tx) port on the port adapter to its receive (Rx) port. In order to set a hard plug loopback, you need a 75 ohms coaxial cable with a male bayonet Neill-Concelman (BNC) connector at each end. Set a Hard Cable Loopback on a BNC Connector If a router passes a hard plug loopback test, the problem lies elsewhere on the E3 line. Hard plug loopback tests determine if the router hardware has any faults. Try to identify the alarm on the local end, and complete the steps suggested in E3 Alarm Troubleshooting. Severely Err Framing Secs and Unavailable Secs IncreaseĮnsure that the local interface port configuration corresponds with the far-end equipment configuration. Refer to Hard Plug Loopback Tests for E3 Lines for more information. Insert an external loopback cable into the port. Look for breaks or other physical abnormalities in the cable.

Line Code Violations and Line Code Error Secs IncreaseĬomplete these steps in order to resolve these errors:Įnsure that the equipment on the remote end of the 75 ohms coaxial cable sends an E3 signal with the HDB3 line code.Ĭheck the integrity of the 75 ohms coaxial cable.

This section describes the various error events that occur on the E3 lines and provides information on how to fix them. Line Errored Secs –– This reports the number of one second intervals in which a Line Code Violation occurs. Unavailable Secs –– This reports the number of one second intervals in which the controller fails. Severely Err Framing Secs –– This reports the number of one second intervals in which either a Remote Alarm Indication is received or a Loss Of Frame condition occurs.
P-bit and C-bit Coding Violations and all derived Err Secs–– These are always zero, because these errors are only defined for T3. Line Code Violations –– This reports the number of received Bipolar Violations (BPV) that are in the HDB3 line code. These are the definitions for the E3 error events, regardless of which port adapter you use: dodi# show controllers e3 4/0ĭata in current interval (81 seconds elapsed):Ġ P-bit Err Secs, 0 P-bit Severely Err SecsĠ Severely Err Framing Secs, 0 Unavailable SecsĠ Line Errored Secs, 0 C-bit Errored Secs, 0 C-bit Severely Errored Error Event Definitions Use the show controllers e3 command in order to view the E3 error events on a PA-MC-E3 port adapter. dodi# show controllers serial 5/0ĭata in current interval (798 seconds elapsed):Ġ Line Code Violations, 0 P-bit Coding ViolationĠ Sev Err Framing Secs, 0 Unavailable SecsĠ Line Errored Secs, 0 C-bit Errored Secs, 0 C-bit Sev Err Secs The PA-MC-E3 Port Adapter Use the show controllers serial command in order to view the E3 error events on a PA-E3 port adapter.

The type of port adapter that you use determines which of the various Cisco IOS® software commands display the E3 error events. Refer to Cisco Technical Tips Conventions for more information on document conventions. If your network is live, make sure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration. The information in this document was created from the devices in a specific lab environment. This document is not restricted to specific software and hardware versions. There are no specific requirements for this document. A section is also provided on Hard Plug Loopback Tests. This document describes the different E3 error events and outlines how to identify and troubleshoot them.
