Standard Format for Jacks

BLDG Omit from jack unless a closet in a different building feeds the jack location. (See Multiple Building Format for Jacks) Use the University designated four character code. Building Lookup
ROOM Room number assigned by Design and Construction. If the jack is in a hallway, use the number of the nearest room. When designated by the Design and Construction floor plan, a room may include the suite, location, or cubical identification, such as A, where A = suite number. (See Standard Room Format and Exception Room Format)
  Note: Ground floor will be used for elevator room.
SEQUENCE A unique number within each room, -1 ,- 2, - 3, etc., designating a specific jack. In areas such as resident halls, the same sequence should be repeated in each room. Sequence numbers will be not be based on the type of service (voice, data, and so on).
  Note: A character will be added at the end of the sequence number if the cable is split, such as A, where A = pairs 1 and 2, B = pairs 3 and 4, and so on.
ROOM TYPE Hallway jacks will be marked with an ‘H’ and ceiling jacks will be marked with a ‘U’ at end of the sequence number. No other room type will be marked.
  Note: If the cable is split and located in a hallway or ceiling, ‘H’ or ‘U’ will precede the split cable code.
SERVICE TYPE Identified by the color of the modular jack or connection device in the jack. (See Jacks-Color Scheme) Written coding will be omitted from the jack. In addition to color coding, service type information will be tracked through the telecommunications software.

Multiple Building Format for Jacks

The only time the jack will include the building code is when multiple buildings are involved in the wire schemes. In those instances the jack / faceplate and patch panel will include the upstream-downstream standardized four character building code. Two labeling strips may be necessary to record the required information on the users jack.
Example: Jack would be labeled: LEVY PCOB 108-2

Standard Room Format

The Design and Construction room number will be used, which should be identified at the room entrance and/or on the floor plan.
Contact Networking and Telecommunications if service is being installed in an area or room that does not have an assigned room number or if the room number does not match the documentation, such as a floor plan. To prevent inaccurate facility records, NEVER create a room number without first consulting with Networking and Telecommunications.

Exception Room Format (wire facilities)

WIRE CLOSETS Wire / facility closets or termination locations that do not have a room name designated by Design and Construction will be named.
T x x z z
Where x x represents the floor ( 0 = basement, 1 = first floor, etc. – including buildings where rooms on the first floor are named with the 100 series numbers.) Where z z represents the physical location based on the closet scheme currently being used by Computer Services Networking group. (N = north, SE = southeast, etc.)
Example: Jack would be labeled: T1SE-2
The Design and Construction room number will be used when wire facilities are located in a shared or multipurpose space.

Abandoned Jacks / Facilities

Abandoned facilities will be tracked in the component-tracking module of the telemanagement software.
