Course Description:
This Hands-On course, Trunk Testing Provisioning and Maintenance, begins with an overview of the 5ESS Switch and the telecommunications Trunking Network.
This overview includes 5ESS Switch Modules, Unit functions and Trunking concepts. Next, the course identifies the Transport Facilities that Terminate in a 5ESS Switch, including Line Coding, Framing and Data Rates. The System Signaling 7 (SS7), Out-Of-Band signaling is presented next and includes SS7 structure, Point Codes, Operation, Output Messages, Testing and Protocol.
The 5ESS Trunk Provisioning presents Recent Change Views (RCV) RCV 5.1, RCV 5.3, RCV 5.5, RCV 10.2, RCV 20.4, RCV 20.24 and RCV 20.31. The Trunk Testing consists of both Automatic and Manual Trunk Testing procedures along with Trunk Testing concepts and result analysis. The tests presented consist of Transmission, Signaling (In-Band and Out-Of-Band), Supervision, Data Rate, Digit Pulsing, Talk and Monitor functions and Manual On Hook and Off Hook tests.
This includes Trunk Line Work Station (TLWS) poke commands and 5ESS Input Messages. The course also presents procedures on Turning Trunks Up For Service including the tests that should be performed and the 5ESS Status printouts that should be requested.
The last lesson covers 5ESS Trunk Maintenance which includes Trunk failure messages such as Machine Detected Interoffice Irregularities (MDII) and System Signaling 7 (SS7) messages. This course includes procedures, tables, charts, and information on the resolution of Trunk Service issues, with recommendations of What To Do Next. 5ESS documentation is used and referenced throughout this course.
The objective of Trunk Testing Provisioning and Maintenance is to train provisioning and maintenance personnel to build translate, turn-up and maintain Trunk circuits in a 5ESS Switch.
