    5. Troubleshooting Latching Loopback (9623, 9626) A latching loopback is a network-initiated DSU Loopback. Once a DSU Loopback is started, the iMarc unit remains in loopback until it receives the loopback-release sequence from the network. The latching loopback code is a control sequence (as opposed to a bipolar violation sequence);...

    5. Troubleshooting Monitor 511 (9623, 9626) For Monitor 511, a 511 test pattern being sent over the network or DTE port interface can be monitored. To view the test results, see the Network or Port-n Physical Tests screen. Main Menu→Test→[Network Physical Tests/Data Port Physical Tests]→ Monitor 511 The current number of bit errors is shown under the Result column when the iMarc unit is in sync.

    5. Troubleshooting Physical Tests (9720, 9783, 9788 CSU/DSUs) iMarc DSL CSU/DSUs support a single physical test for the data port, the DTE Loopback. This test does not appear for the routers. DTE Loopback (9720, 9783, 9788 CSU/DSUs) The local DTE external Loopback (DTLB) loops the received signal on the DTE interface back to the DTE without affecting the operation of the remaining ports.

    5. Troubleshooting IP Ping Test An IP Ping test can be run to test connectivity between the iMarc unit and any iMarc unit, router, or NMS to which it has a route. Times when you might want to run an IP Ping test are: „...
  • Page 193 If the address or subnet does not appear in the routing table, the ping will be sent to the Default IP Destination, if defined. (See Configuring Node IP Information in the iMarc SLV Configuration Reference.) Port-n, Net1-FR1 – The ping is sent out the specified destination regardless of the internal route configuration.
  • Page 194 When a COS definition is selected, the TOS byte value is read-only. If you select a COS definition that has multiple COS IDs, the lowest value is used as the TOS byte. See Configuring Class of Service Definitions in the iMarc SLV Configuration Reference. 0000–1111 – The value of the TOS byte.
