This lesson, Overview of the Trunking Network, presents 5ESS Switch and the telecommunications Trunking Network. The lesson provides a basic overview of the 5ESS Switch Modules, Peripheral Unit and Peripheral Unit call processing functions. Next, this lesson presents an overview of telecommunications Trunking concepts, such as: trunk connections, transport facilities, signaling, trunk classes, trunk types, and others. This lesson establishes the basic knowledge needed for the following lessons. This lesson includes references to Alcatel-Lucent’s Dyna Text 5ESS Switch support documentation.
The Transport Facilities in a 5ESS Switch lesson presents the Analog and Digital Transport Facilities available and the peripheral units they terminate on in a 5ESS Switch. The lesson begins by defining transport facilities within the telecommunications industry. This is followed by identifying how these transport facilities terminate in the 5ESS Switch. In order to understand Digital Facilities, the students need a short analog/digital conversion presentation which is presented next. This leads into Line Coding, Framing, Data Rate and Signaling along with where these items are optioned in the 5ESS Switch. The lesson completes by presenting 5ESS Performance Monitoring and 5ESS Switch Transport Facility fault analyzation procedures. The lesson includes references to Alcatel-Lucent’s Dyna Text 5ESS Switch support documentation and relates procedures in the lesson to this documentation.
This lesson presents System Signaling 7 (SS7) and its features. The lesson begins with an overview of common trunk signaling methods currently in use. This is followed by presenting the SS7 operational platform structure and linkage configurations. Next the lesson presents 5ESS Switch trunk related SS7 Input and Output messages. These Input and Output messages are essential for verifying and testing the provisioning of SS7 trunks in a 5ESS Switch. The SS7 Service Control Point (SCP) is presented along with INWATS and Local Number Portability (LNP) query procedures. The last part of this lesson presents 5ESS SS7 Protocol Monitoring. The advantage students gain from the material presented in this lesson is the ability to use 5ESS SS7 Input and Output messages during circuit provisioning and maintenance. The lesson references to Alcatel-Lucent’s Dyna Text 5ESS Switch support documentation and relates procedures in the lesson to this documentation.
This lesson, Provisioning Trunks in a 5ESS Switch, presents the 5ESS Recent Change Views used to establish Trunk Services. This lesson addresses the fields and their functions on the following 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 lesson also provides Trunk Class (RCV 5.1) descriptions and how these trunk types are translated. This lesson also presents a Line to Trunk and a Trunk to Line call flow based on Recent Change Views. The lesson includes references to Alcatel-Lucent’s Dyna Text 5ESS Switch support documentation and relates procedures in the lesson to the documentation.
This lesson presents Trunk Testing procedures, concepts and result analysis. This lesson presents Trunk maintenance procedures with the emphasis placed on the actual testing of trunks. These tests consist of Transmission (Levels – Loss, Noise, Noise With Tone and Gain Slope), Signaling (In-Band and Out-Of-Band), Supervision, Data Rate (BERT, Loop Back, etc.), Digit Pulsing (In Service Monitoring), Talk and Monitor functions, Automatic 102 and 105 Tests, and Manual On Hook and Off Hook tests. The lesson initially presents 5ESS Switch input and output messages associated with: the status of trunks, trunk lists, trunk tests, and how to change the operational state of a trunk. The lesson addresses the Circuit Administration State (CADN) and state changes as presented in the Output Messages Manual (235-600-750) Appendix. From this point, the lesson presents different trunk tests from the Trunk Line Work Station (TLWS) poke commands and 5ESS Input Messages. Along with Trunk Testing, this lesson presents a procedure to detect looped facilities. This lesson includes references to Alcatel-Lucent’s Dyna Text 5ESS Switch support documentation and relates procedures in the lesson to the documentation.
Turning Trunks Up For Service presents Procedures, Tests and 5ESS Status Printout requests that should be performed and requested prior to placing trunks in an In Service state and before routing Call Traffic over them. These procedures can consist of common procedures used and accepted within the telecommunications industry and/or customized with your own company’s established procedures. These common procedures consist of: Trunk Status and State verifications; Manual and Automatic Transmission Tests; In-Band and Out-Of-Band Signaling Test Procedures; System Signaling 7 (SS7) Trunk Lists, Verifications and Queries; and Call Through Tests. This lesson includes references to Alcatel-Lucent’s Dyna Text 5ESS Switch support documentation and relates procedures in the lesson to the documentation.
This lesson presents Pro-Active 5ESS Trunk Maintenance. This includes the analysis of Trunk failure messages such as Machine Detected Interoffice Irregularities (MDII) messages, System Signaling 7 (SS7) messages, Trunk Error Analysis (TERA) reports, Plant 24 Reports and Transport Facility Performance Monitoring error reports. Each topic includes recommendations of “What To Do Next.” Alcatel-Lucent’s 5ESS documentation is used and referenced throughout this lesson.
