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)

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”
