Agenda

  • Overview of Network Services

    • Voice Services

    • Data Services

  • Current Challenges

  • Future Challenges

  • Tour of Physical Facilities


Presenters

  • Harold Esche, P.Eng, MBA

    • CIO, University of Calgary

  • Tom Seto, BSc, BComm

    • Associate Director, Information Technologies


Convergence

  • Prior to April, 2004, Telecommunications was a department of Campus Infrastructure

  • On April of this year, Telecom was merged with Information Technologies’ Network Services Group

  • While Network Services was responsible for networks on campus, they subcontracted the actual installations to Telecomm


Current Organization Chart


Current Infrastructure

  • Two parallel infrastructure

    • Cabling

    • Equipment

  • Both are costly to install and maintain

    • Moves, Adds, Changes (MAC)


Network Services

  • Voice Services

  • Network Operations

  • Security

  • Other


Telephone Systems

  • Nortel SL 100 Software Rel. MSL 14

  • 9550 installed telephone services

  • 672 bi-directional PRI trunks

  • 20 % future spare capacity

  • ~108,000 calls per day


Telephone Systems

  • 40,000 kilometers of copper cable

  • 57 main distribution Telecom rooms

  • 320 intermediate distribution rooms

  • 25,000 pairs leave the main switch room


Voice Systems

  • Cabling

    • Cables are pulled from the Admin Bldg to each other building on campus

    • These cables are 400 to 800 pairs

    • They end in main distribution rooms (MDT)

    • There are intermediate distribution rooms throughout the building (IDT) from which cable is installed for each user location (home runs)


Cabling

  • 80% of home runs are Cat 3

  • Require Cat 5 or greater for current technologies – gigabits/sec


Installing a Telephone Service

  • A pair of cables in the home run is selected

  • A connection is made in the IDT from the home run cable to a pair in the riser cable which goes down to the MDT

  • A connection is made in the MDT from the riser pair to a pair in the cable going back to the telephone switch in the Admin Bldg

  • In the Admin Bldg, a connection is made from that pair to a line card in the phone switch


Voicemail Systems

  • Avaya Aria 350

  • Software Rel. 3.1

  • 5500 installed personal mailboxes

  • 55 special application mailboxes

  • ~300,000 calls to system per month

  • Accepted as a “Messaging System”


Telecom Systems

  • Voice Services

  • Network Operations

  • Security

  • Other


Networking Systems

  • Over 10,000 Active Network Connections to support Research, Administration and Teaching

  • Central Network Management (SNMP)

  • Gigabit backbone links

  • AirUC – wireless network


Networking Systems

  • Fiber optics backbone

  • 816 kilometers of fiber

  • 32 Fiber nodes on campus

  • Remote direct connections to Mount Royal College and University of Alberta

  • Secure / Non Secure Networks

  • Internet Access
