PIIS start upExpectations on Branch Online
EnvironmentUser Awareness

• Presentation By Peerless Computer Center
• 12th November, 2002

2
Foremost Commitment

• Please do not experiment with the
• system or devices
• IN Online mode this might spoil your
• work and also others connected with
• You
• Ensure correct input to expect a correct output
• Data correction after End Of Day session is not
  permitted by PIIS as this data gets replicated in
  the Central Server

What are my Systems Resources ?

• Branch Server (high end PCs)
• runs on LINUX operating system loaded with
  J2SE software
• Branch Nodes (PCs) runs on LINUX J2SE software,
  connected to the Server over LAN
• Routers Modems for Wide Area connectivity over
  ISDN or Leased Line
• VSAT outdoor indoor units for satellite
  connectivity
• Oracle 9i Database
• PIIS Application Software

How should I care my resources?
DOs AND DON'Ts

• Switch off monitor when not in use
• Share your password with anybody
• use unauthenticated floppies which may contain
  virus

• Before switching on your computer check whether
  all the devices are connected
• Keep Server, Nodes, Router, VSAT Indoor Unit etc
  in A/C Dust free room
• Install VSAT outdoor unit on rooftop

DOs AND DON'Ts

• Before switching off the computer, do a complete
  shutdown
• Ensure printer is connected and paper fed before
  taking printouts

• Taking printouts of graphics and designs and
  waste ink
• Download / install software without authorisation
  from administrator

How should I care my resources?
Continued
DOs AND DON'Ts

• Branch Administrators do Startup and Shutdown
  procedures daily
• Ensure correctness of data at entry level
• Do End-of-day Processing
• Ensure UPS support to protect abrupt power
  failure

• Branch Administrators
• do not change passwords
• Branch Administrators Allow End-of-day
  Processing without clearing backlog
• Let out passwords
• Run the System even if UPS is down

How should I care my resources?
Continued
DOs AND DON'Ts

• Delink WAN after successful SOD EOD
• Keep an eye on Maintenance of the devices
  engage Company approved agencies

• Keep the link up even when connectivity is not
  required pay a huge telephone bill
• Assume Machines will work fine every hour
  service by any one will do

9
How I am connected with Data Center ?

• Your Branch is connected to the Data Center by
  ISDN/ Leased Line/ VSAT
• Service Center(SC) is connected to the parent
  Branch by ISDN through out the customer service
• Generally the Branch will connect Data Center
  twice a day
• At the Start Of Day (SOD)- to check downloads
• At the End Of Day (EOD) to upload data
• Delink after SOD relink for EOD

10
How should I register my service call ?

• For all H/W S/W services register your call
  with RCC by fax, telephone or mail (future)
• RCCs will issue a docket no. for every call
• For all Network services, register your call with
  N/W nearest help desk
• You may escalate the call to PCC after a
  reasonable wait
• RCCs may escalate the call to PCC if it is beyond
  their capacity
• All RCCs will submit a call status report every
  Monday to PCC. Report format will be supplied by
  PCC
• PCC RCCs will ensure that no call is open
  beyond three days

11
How do I get training to operate PIIS ?

• On hand operation training will be given by
• PCC/ RCC team before PIIS implementation at
  your Branch
• Network equipment handling training will be
  provided by the Network Service provider
• User Manuals will be provided to every Branch
• Self learning assisted by peer
• Play role model in training your own team
• Suggestions on User Manual are welcome

AWARNESS ABOUT NETWORK
13
Why What is a Network ?

• Introduction
• Network Fundamentals
• Local Area Network (LAN)
• Wide Area Network (WAN)
• Operating Networks

14
What is a Network

• A Network is the framework that enables two
  or more computers to communicate with each other
  and/or other devices.

15
Why do we need a Network ?

• Share Processing Power
• Share Information

16
Network Components

• Hardware Components
• Transmission Facilities Physical media (Cable,
  Radio etc.)
• Access Devices Network Interface Card (NIC)
• Forwarders Such as Hub, Bridge, Switch, Router
  etc.

17
LOCAL AREA NETWORK
18
LAN-Attached Devices

• Servers Multi-user computers
• File Servers
• Print Servers
• Application Servers
• Database Servers
• Clients Any computer that accesses resources
  stored on servers, via the LAN
• Printers

19
Transmission Media

• Tangible transmission media
• Coaxial cable
• Twisted pair wire
• Shielded Twisted Pair (STP)
• Unshielded Twisted Pair (UTP Cat-3 and Cat-5)
• Fiber-optic cable
• Multimode
• Single mode

20
Networking Hardware

• Network Interface Cards (NIC)
• Repeaters
• Hubs
• Bridges
• Routers
• Switches
• Gateways

21
Wide Area Networks

• WANs enable LANs at various geographic distance
  to be networked together.
• The WANs technology base includes the following
• Transmission Facilities
• Communication Hardware.
• Inter-network Addressing
• Routing Protocols

22
Transmission Facilities

• Leased Lines
• Circuit-Switched Facilities
• Integrated Service Digital Network (ISDN)
• Switched 56 (Dial-on demand 56 Kbps)
• Leased Line Modems
• Routers

23
Leased Lines

• A Leased Line is a permanent telephone connection
  between two points set up by a telecommunications
  common carrier.
• Leased Lines are used by businesses to connect
  geographically distant offices.
• Unlike normal dial-up connections, a leased line
  is always active and can assure a given level of
  quality.

24
ISDN (Integrated Services Digital Network)

• It is an international communications standard
  for sending voice, video, and data over digital
  telephone lines. There are two types of ISDN
  available BRI and PRI.
• BRI (Basic-Rate Interface) consists of two
  B-channels that can carry voice or data at rate
  of 64 Kbps, and one D-channel, which carries
  call-control information. BRI is designed for
  individuals and small businesses.
• PRI (Primary-Rate Interface) consists of 23
  B-channels (30 in Europe) and one D-channel. PRI
  service is generally transmitted through a T-1
  line (or an E1 line in Europe).

25

What is a Modem ? The device used to connect
the computer to a tele line is called ModemThe
device MODulates DEModulates signals from
Analog to Digital vise versa
26
Satellite Communication Device

• VSAT
• ( Very Small Aperture Tube )
• We have selected ku broad band
• 1.2 meter diameter antenna
• SKY Blaster model
• VSAT has two units
• 1. Out door unit consisting of Antenna
• positioned south east open facing
• 2. Indoor unit bundled with modem
• Hub Center to control VSAT Network
