CS 406/407 Project Goals

Provide complete life cycle experience for students

Provide a useful tool to aid in the development process

Tellabs Operations Inc.. 7

Intro to the Tellabs Development Environment

Software is compiled in the Solaris environment

Target hardware processors are all Motorola 68000 / PPC based

Software is uploaded from the SUN to the TITAN via an external SCSI link

The Zen of Requirements

Requirements are driven by a product not vice versa

Requirements change at the most inconvenient times

There are few wrong answers but some are more right than others

TITAN 532L Primer

Major SystemsAdministrative Complex (AC)Network Switch Complex (NSC)Port Switch Complex (PSC)

Port Modules (DS3 or DS1 equivalents)NPCs (DS0 equivalent)

Tellabs Operations Inc.. 10

Standard Data Format (SDF)

SDF is the heart of 532L 1 SDF contains 860 timeslots DS0 data mapped to SDF 532L supports 256 SDFs SDF travels through switching network SDF converted back to DS0

Tellabs Operations Inc.. 11

Administrative Complex

532L has 2 ACsOne active, one inactiveIf active fails, inactive reboots to become active

User interface Non-volatile data storage LAN Hub Network Timing

Tellabs Operations Inc.. 12

Network Switch Complex

532L has 2 NSCsIf one copy fails, the other instantly takes over

Route data from point A to point B Network timing distribution Five stage switching network

Tellabs Operations Inc.. 13

Port Switch Complex

Roughly 16 PSCs supported by 532LUp to 256 SDFs

There are three types of PSCs

Tellabs Operations Inc.. 14

LD100 PSC Type

Low Density PSC 16 SDFs Up to 256 DS1

Modules 8 DS3 Modules Any combination

Tellabs Operations Inc.. 15

Port Module

Cross Connect (TCON) 532L TCONs at DS1 and DS0 level 1 DS1 or 1-24 DS0s connected at a time Data travels from

Port module on PSC xCross connected through NSCEnds up at port module on PSC y

Standard cross connects are two way Conference cross connects are one way

What is the CCG?

Tool to create CMD files to run on 532L An API to allow to easily add new features

and to help keep it up to date. A GUI front end to help users create the

CMD files.

Tellabs Operations Inc.. 23

CCG: What it will do

Generate a CMD file to run on the 532LThe CMD is list of TCON and other

configuration commands.A typical CMD file may have anywhere from

100 to 20,000 commands.

Tellabs Operations Inc.. 24

CCG: Why it is needed

Configuring 532L is very slow. Complete configuration takes 6-10 hours Existing tools

Hard to findDon’t workOut of date

Tellabs Operations Inc.. 25

Who will the CCG benefit?

The CCG will benefit 532L development, testing groups and customer support groups.

Tellabs Operations Inc.. 26

How CCG Works

CCG creates a CMD fileSimilar to shell scriptList of commandsNo iteration or branching statementsNo error checking

532L executes each command in CMD file

Tellabs Operations Inc.. 27

Cross Connect Algorithms

Algorithms required for efficient use of developer time

Algorithms take range of port modules and NPCs and apply algorithmoffset = 512for (cur_npc = 1; cur_npc <=448; cur_npc++)

tcon::fromdc cur_npc to cur_npc+offset

Tellabs Operations Inc.. 28

Configuration File

CCG will define: Which PSCs are in 532L Which port modules and NPCs in 532L Port module and NPC configuration Algorithms to use

Tellabs Operations Inc.. 29

CCG Output

First CCG reads configuration file Determines entire range of port modules

and NPCs Applies algorithm to range of port modules Prints out resulting series of 532L

commands as a CMD file
