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 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) • 10 / 100 Mega-bit Speeds • 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
AirUC • Wireless network for all IT username holders
WANs • Internet – ISP is Telus • Shaw – Direct 100Mbps connection • Netera – high speed to worldwide research networks • SuperNet • Intranets • Wireless • Dark fiber
Network Services • Voice Services • Network Operations • Security • Other
Security Systems • Alarm Systems installed city-wide • Full monitoring system in security • Campus 1 Card • Access control • CCTV surveillance • Emergency Alarms
Telecom Systems • Voice Services • Network Operations • Security • Other
Other Systems • Olympic Oval Timing and Scoreboards • Radio Systems • Paging Systems • Help Phones • Cable Management • TelePlus Billing
Challenges • Converging Voice and Data over one infrastructure • Wireless – Local Area and Wide Area • Bandwidth Challenges • Upcoming Technologies • $$$$$
