Lesson 1 - ISDN BRI Fundamentals

Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) Fundamentals presents an overview of the functional and operational structure of ISDN BRI service. This lesson briefly defines analog line side service off of a 5ESS Switch and then compares it to ISDN line side service also off of a 5ESS Switch.  The lesson addresses S, R, T and U interface points, 2 B plus D service, Custom ISDN versus National/Standard ISDN, AMI versus 2B1Q, CPE, Network Termination 1 (NT1), Network Termination 2 (NT2), Terminal Adaptor (TA), Circuit Switch Voice (CSV) and Circuit Switch Data (CSD).  This lesson establishes the basic knowledge needed for the following lessons.

Lesson 2 – ISDN BRI 5ESS® Hardware

Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) 5ESS Hardware presents the hardware equipment in the 5ESS Switch used to provide ISDN BRI service. This lesson provides a brief overview of the modules and units within a 5ESS Switch.  It then presents the Integrated Services Line Unit model 1 (ISLU), Integrated Services Line Unit model 2 (ISLU2) and Access Interface Unit (AIU) in detail with emphasis to the ISDN service they provide.  This lesson presents the functional and physical structure of the units, 5ESS Switch display screens, diagnostic information and Input Messages pertinent to maintenance and customer service.  This is followed by defining the functional and physical structure of the Packet Switch Unit model 1 (PSU) and Packet Switch Unit model 2 (PSU2).  The PSU and PSU2 portion of this lesson includes Quarter Time Slot discussions, Integrated Services Circuit Number / Packet Office Equipment (ISCN/POE) number information, Channel Group and Channel Assignment information plus Time Slot Reservation information.  The PSU/PSU2 portion of this lesson addresses where layer 2 (LAPD and Q.921) protocol is processed.  It establishes the physical 5ESS Switch equipment knowledge of how an ISDN BRI operates and provides the “ground work” for the ISDN BRI Translation lesson.  The following equipment Recent Change Views are presented in this lesson.

· RCV 20.16 – Access Interface Unit Pack

· RCV 22.2 – Equipment Unit – Packet Switch Unit

· RCV 22.7 – ISLU Line Card

Lesson 3 – ISDN BRI Translations

Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) 5ESS Translations presents the 5ESS Switch Recent Change Views and translations that provide ISDN BRI service. This lesson begins with a brief overview of the 5ESS Switch Recent Change process.  It then presents the following Recent Change Views and their fields:

· RCV 23.2 - DSL Subscriber Line 

· RCV 23.8 – DSL/BRCS Assignment

· RCV 23.20 – Primary or Secondary Only Key Systems

· RCV 23.21 – ISDN Terminal Type C/D Key Systems

· RCV 23.22 – Call Appearances and Feature Buttons

· RCV 23.30 – ISDN DSL/USER Copy

· RCV 12.5 – Configuration Group Definition

· RCV 22.2 – Equipment Unit – Packet Switch Unit

· RCV 22.12 – ISLU - DPIDB

· RCV 22.14 – Channel Group Channel Assignments

Lesson 4 – ISDN BRI Call Processing and Features

The ISDN BRI Call Processing and Features lesson presents how the 5ESS Switch processes calls, the Recent Change Views used to route the call and Feature interaction.  The lesson includes a Line to Line call, Trunk to Line call and a Line to Trunk call.  The purpose of this lesson is to present the Call Routing Recent Change Views and fields that affect call routing (ISDN and Analog) and how they interact with the ISDN BRI services, features and options.  The Recent Change Views presented in this lesson include:

· RCV 1.6, 1.8, 23.2 and 23.8 – Analog Line and Digital Subscriber Line

· RCV 4.1 – Line Class Code

· RCV 9.1 – Digit Analysis Selector

· RCV 9.2 – Prefix/Feature Digit

· RCV 9.3 – Local Digit

· RCV 9.7 – Remaining Digit

· RCV 10.3 – Carrier Administration (Interconnect Carrier Form – ICF)

· RCV 9.7 – Carrier Destination Mapping

· RCV 10.10 – Screening

· RCV 10.11 – Charge Index Expansion

· RCV 8.2 – Normalized Office Codes

· RCV 4.14 – Hundreds Group Assignment

· RCV 10.2 – Route Index

· RCV 10.25 – Alternate Route Indexes

· RCV 5.1 – Trunk Group

· RCV 5.5 – Trunk Member

· RCV 9.5 – Incoming Trunk Digits

Lesson 5 – ISDN BRI Protocol

The ISDN Basic Rate Interface Protocol lesson begins by generally defining protocol.  This includes presenting the International Standards Organization’s (ISO) Open Systems Interconnect (OSI) seven layer model and explaining where the ISDN BRI protocol fits into the model.  From this point, the lesson identifies ISDN BRI Layer 1 (I.430), Layer 2 (Q.921, LAPD) and Layer 3 (Q.931) protocol along with their equipment terminations within the 5ESS Switch and at the Customer Provided Equipment (CPE).  The lesson presents the function of each level of protocol, how that level of protocol becomes operational and examples of the Protocol messaging.  This includes a detailed explanation of how the “D” Channel becomes operational.  Next, the lesson presents Q.931 call processing messages.  The lesson references Alcatel-Lucent’s National ISDN Basic Rate (235-900-341) and Custom ISDN Basic Rate (235-900-343) documents. 

Lesson 6 – Maintenance Messages

This lesson, Maintenance Messages, presents the 5ESS Switch Input and Output messages used to maintain customer service, correct service problems, verify status and obtain information about a customer’s ISDN BRI line and service.  The lesson also includes an explanation of the different 5ESS BRI protocol error detection schemes.  It also includes a brief overview of how to use Alcatel-Lucent’s Input and Output messages manuals.  This is followed with a presentation of the following Input Messages and analyzing their associated Output Messages. 

· OP:STATUS (Includes Output Messages Manual Appendix “Port Status”)

· OP:LIST

· OP:CPE

· TST:DSL

· EXC:ALE

· VFY:OFC

· OP:CONV

The goal of this lesson is to provide a strategy to identify and correct ISDN BRI service problems.

Lesson 7 – BRI Protocol Monitoring (EXC:PM)

This lesson, BRI Protocol Monitoring (EXC:PM), presents the 5ESS Switch BRI Protocol Monitoring feature.  It provides the EXC:PM input message and defines the various options and parameters of the message.  After the message has been presented, this lesson presents several protocol example session.  The resulting printouts are analyzed using Alcatel-Lucent’s National ISDN Basic Rate (235-900-341) document and their Custom ISDN Basic Rate (235-900-343) document.  This lesson references Alcatel-Lucent’s Dyna Text 5ESS Switch support documentation and relates procedures in the lesson to the documentation.
