3. Presenters Harold Esche, P.Eng, MBA –CIO, University of Calgary Tom Seto, BSc, BComm –Associate Director, Information Technologies

4. 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

5. Current Organization Chart Manager Network Operations Router Team Security Services Voice Services

6. Current Infrastructure Two parallel infrastructure –Cabling –Equipment Both are costly to install and maintain –Moves, Adds, Changes (MAC)

7. Network Services Voice Services Network Operations Security Other

8. 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

9. 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

10. 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)

11. Cabling 80% of home runs are Cat 3 Require Cat 5 or greater for current technologies – gigabits/sec

12. 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

13. 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”
