Course Description:
This detailed and extensive course provides the skills and practical understanding to perform maintenance and troubleshooting of the Nokia (formerly Siemens) EWSD switching system, and its various remotes options including the DCO ONE-Up feature. It discusses the use of maintenance terminals such as the OMT, EAI, and SYPD, including the use of the Smart Commander, and BCT Boot, BMML, and Alarm Console programs, and also looks at system output messages like Maintenance Message Numbers (MMN) and Fault Location Numbers (FLN). Several Electronic Document Delivery System (EDDS) books are reviewed, including the Trouble Locating Manual (TLM), Trouble Analysis Procedures (TAP), and Detailed Level Procedures (DLP). Key Books such as 0200, 0825, and 1088 are covered in detail, using several examples.
Previous types of troubles are reviewed and used as exercises, including line and trunk maintenance, Line Trunk Groups (LTG), Digital Line Unit (DLU), and DIUDLUS modules. All digital exchange Switching Network (SN) options are discussed, including the DE3, DE4, DE51, DE52 and DE54. The IOP processor architecture is also included, with a discussion of how MB, SCDP, BAP, CAP, and other CP113 components fit together. Various versions of the CP113 are compared to the actual configurations used in the local switch. Clocking, the CCNC and SS7 are also discussed, so students understanding how A links connect to STPs.
GR-303 RDT remotes (Release 25) and the DCO ONE-UP (LLS RLS re-home) options, and IPH packet module can be included, depending upon the local network topology.
Our non-intrusive exercises equip the student to conduct day-to-day maintenance activities, perform troubleshooting procedures, including cabling and parts of the backplane, and much more. The course is flexible, allowing the most important content for a particular group of students to be emphasized.
