single line sets and Panasonic with special feature keys. Speaker phone
service is available with these sets. A message waiting lamp is provided
for most sets.
2.4 Battery backup with over 1 hour reserve is provided for the SL1 PBX.
2.5 The call accounting system is manufactured by INFORTEXT Model OS 200.
A small battery backup is porvided for this system.
2.6 A maintenence contract for the PBX and associated equipment has been
negotiated with the General Telephone Company.

Cabling System
3.1 Manholes and Conduit
3.1.1 A central manhole serves Hayes and Middlefork Halls.
3.1.2 Conduits are utilized between Whitewater hall and the central manhole.
Conduits connect the manhole to Hayes and Middlefork Halls.
3.1.3 Interliners are used for fiber and coaxial cables.
3.2 Cable Racks
3.2.1 Cable racks are utilized in all buildings. These are usually provided
for each floor of the building.
3.2.2 Copper, coaxial and fiber cables utilize the cable racks.
3.3 Interbuilding and Riser Cables
3.3.1 All interbuilding copper cables hub at the Main Distribution Frame(MDF)
located with the telephone switch in Whitewater Hall.
3.3.2 Copper riser cables are provided from the building equipment room
to the individual floor equipment rooms in all three buildings.
3.3.3 Interbuilding and riser copper cables are used basically for telephone
service.
3.4 Fiber Optic Cabling
3.4.1 The fiber optic hub for this campus is located in Hayes Hall with
the computer services equipment.
3.4.2 The fiber cabling utilizes a star topology from the hub with individual
cables serving each bulding on the campus. Each fiber cable consists of
8 multimode and 4 single mode fibers.
3.4.3 Fiber riser cables consisting of 8 multimode and 4 single mode fibers
are installed between the building equipment rooms and the individual floor
equipment rooms.
3.5 Coaxial Cable
3.5.1 Interbuilding coaxial cables have the hub in the boiler room located
in the basement of Whitewater Hall. Utilizing a star topology two 500 type
coaxial trunk cables connect each building with the hub.
3.5.2 Riser and horizontal intrabuilding coaxial cabling is as follows:
3.5.3 Hayes Hall
3.5.3.1 Cabling between the building distributing frame and the floor distributing
frame is the hub.
3.5.3.2 Horizontal cabling is run from the floor distributing frames to
the user's "F" connector.
3.5.4 Whitewater and Middlefork Halls
3.5.4.1 Coaxial cables are probided from the building distributing frame
through the risers to the horizontal racks. On the horizontal racks, they
are "T" tapped to the user's "F" connectors.
3.5.4.2 Splitting amplifiers are provided at the distributing frame locations.
3.6 Station Cabling
There are several station cabling applications used on the Richmond campus:
3.6.1 Whitewater Hall
3.6.1.1 Uses Category 5 cabling, terminations and jacks. Two 4 pair unshielded
cables serve the voice and data RJ45 jacks utilizing 110 type terminating
blocks in the equipment rooms.
3.6.1.2 Also there are a number of stations served by 8 - pair IU standard
category 5, 8 pair IU standard cabling consisting of 6 unshielded and 2
shielded pairs. These cables are terminated on RJ45 jacks and 66 type terminating
blocks at the equipment rooms.
3.6.2 Middlefork Hall
3.6.2.1 Two configurations are also used in Middlefork Hall. One method
utilizes category 5, 8 pair IU standard cabling consisting of 6 unshielded
and 2 shielded pairs. The cables are terminated on RJ45 jacks and 110 blocks
in the equipment rooms.
3.6.2.2 The other method uses two 4 pair unshielded cables terminated on
RJ45 jacks and 110 blocks in the equipment rooms.
3.6.2.3 In both cases the wiring, jacks, and terminations are category 5.
However, the cabling was terminated on the RJ45 jacks per an outdated IU
standard and testing indicates the following:
Pairs 1 and 2 meet category 5 testing standards.
Pairs 3 and 4 meet category 3 testing standards. If these pairs are needed
for category 5 assignments (in the future), the pairs should be reterminated
on the jacks in agreement with 568A jack terminations.
3.6.3 Hayes Hall
3.6.3.1 This building uses a composite copper and fiber cable from the floor
equipment room to the desktop.
3.6.3.2 The fiber sheath contains 2 multimode and 1 singlemode fiber.
3.6.3.3 The sheath for copper contains the IU 8 pair Category 3 cabling.
Four unshielded pairs serve the voice RJ45 jack and the data RJ45 has two
unshielded and two shielded pairs terminated.
3.6.4 Connersville Classroom
This area uses two 4-pair unshielded cables terminated on RJ45 jacks and
110 blocks at the network interface.
3.6.5 Area 9 Agency for the Aged
This office area uses two 4-pair unshielded cables terminated on RJ45 jacks
and 110 blocks at the network interface.
3.6.6 Future Cabling
3.6.6.1 The IU East campus has selected the 4-pair, UTP, Category 5 cabling
for both the voice and data jack wiring. All changes and additions to the
station wiring shall utilize this standard.
3.6.6.2 RJ45 Category 5 jacks are utilized using Option A covered in Attachment
I.
