  1. Austin Peay State University Telecommunications Overview April 16, 2002 Jim Spriggle Telecommunications Manager

  2. NEC NEAX 2400 PBX • Located in Browning • Five processor groups • >2000 lines on campus • Digital and analog phone lines • All trunks to off-campus locations

  3. Remote Switches • Fort Campbell Bldg. 202-NEC 2000 • Fort Campbell Bldg. 604-NEC 2000 • 106 Public Square-NEC 1000 • Shasteen Bldg.-NEC 2000 • New Commons Bldg.-additional switch proposed

  4. Trunk Types • Copper-traditional trunks to LEC • T-1 • PRI (Primary Rate of Interface) • DTR (Digital Trunk Route)

  5. Copper Trunks • Each trunk is a copper cable pair to the local telephone company • One incoming or outgoing call per trunk • Several types, typically ground-start

  6. Digital Trunks, T-1/PRI • PRI is an enhanced version of T-1 which can pass caller ID Information • Use 2 copper cable pairs for physical connection • Data is digital/multiplexed • Each is the equivalent of 23 copper lines • Can be one-way or both way

  7. Digital Trunks, Part2 • T-1/PRI have 24 channels, one is used as a control channel • DTR trunks use all 24 channels for voice • Parts of T-1s can be split out for video-we have “6 lines” of one T-1 dedicated to video to off-campus sites

  8. Austin Peay only Trunks • T-1 to Ft. Campbell • Data T-1 to Ft. Campbell • Video T-1 to Ft. Campbell • T-1 to Public Square • T-1 to Shasteen • Shasteen has 3 copper trunks to Bell South

  9. Copper Trunks • TG5-14 ground start copper trunks to Bell South • Routinely used for outgoing modem traffic • These are our emergency trunks in case of switch failure • TG2-2 ground start copper trunks from Bell South • Calls to campus for long distance access

  10. Local Trunks • Seven PRI to New South • TGs 10, 12, 14, 28, 32, 34, 44, 54 • 28 and 32 are a single PRI split into 6 lines dedicated to video and 17 lines for voice, therefore two TG designations

  11. Outgoing Local trunks • First Choice is TG 54 • Second Choice is TG 44 • Third Choice is TG 34

  12. Incoming Trunks • First choice is TG 10 • Second choice is TG 12 • Third choice is TG 14 • Incoming long distance is routed through the incoming trunks from New South

  13. Special Purpose • Outgoing modem traffic • First choice is TG 5 (copper to Bell South) • Second choice is TG 28 (PRI shared with video) • Third choice is TG 14 (which is the third choice for incoming calls • This will probably change with residence hall networking completed

  14. Long Distance • 2 DTR groups with Quest • TG4: most outgoing long distance, 24 lines total • 24 hrs weekday example 1236 total calls (103/hr) • TG 36: 1-800 calls, 24 lines total
