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
![Page 9: U OF C Information Technologies Network Services Group Voice Services Network Operations Security Services](https://reader033.vdocuments.net/reader033/viewer/2022051618/56649d405503460f94a1afce/html5/thumbnails/9.jpg)
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
![Page 10: U OF C Information Technologies Network Services Group Voice Services Network Operations Security Services](https://reader033.vdocuments.net/reader033/viewer/2022051618/56649d405503460f94a1afce/html5/thumbnails/10.jpg)
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)
![Page 11: U OF C Information Technologies Network Services Group Voice Services Network Operations Security Services](https://reader033.vdocuments.net/reader033/viewer/2022051618/56649d405503460f94a1afce/html5/thumbnails/11.jpg)
Cabling
• 80% of home runs are Cat 3
• Require Cat 5 or greater for current technologies – gigabits/sec
![Page 12: U OF C Information Technologies Network Services Group Voice Services Network Operations Security Services](https://reader033.vdocuments.net/reader033/viewer/2022051618/56649d405503460f94a1afce/html5/thumbnails/12.jpg)
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
