Telecommunications Design 17
- System Design: Backbone Distribution System
A backbone distribution system is the part of the premises distribution system that provides connection between
telecommunications spaces. Typically connecting between floors and other campus buildings.
A. Backbone Fiber Optic Cabling Type and Quantity:
- A new clinic or offsite facility may require ITS fiber optic infrastructure. Coordinate your site plan
and conduit entrances with both the University of Iowa ITS department as well as HCIS.

B. Backbone Copper Cabling Type and Quantity:
- All telecommunications rooms built out within the campus shall require a backbone voice copper
backbone cable. Provide a minimum 50-pair Category 3 cable from a coordinated location to the
new telecommunications room. Cable shall terminate on the wall to a Category 6-rated 110 block
- Forty-eight (48) Category 6 cables shall route from a dedicated 48-port patch panel mounted on a
relay rack to a wall location in the telecommunications room adjacent to the multi-pair voice riser
cabling. The Category 6 cables shall terminate to a Category 6-rated 110 block. Each pair shall be
terminated. This will become an administration point and final cross-connect field from horizontal
cables to the voice riser cabling.
- System Design: Horizontal Cabling Systems
This is the portion of the cabling system that extends from the work area outlet to the horizontal cross-connect
(telecommunications rooms) in the appropriate space. This includes: category 6 cabling, telecommunications
outlets/connectors, mechanical terminations and patch cords. It may also include multiuser telecommunications
outlet assemblies. Refer to the appendix for product specific information.
A. Category Cable Type and Quantity
- Depending on the location, end-user, and systems scheduled, a minimum of Category 6 shall be
required. See the table below for each system and the type of cabling to be utilized:
Performance Grade of Cable System Served # of cables
Category 6 Typical Work Area Outlet Min. 2
Category 6A Wireless Access Points Min. 2
Category 6A Shielded Telemetry Varies
Category 6A Shielded HDBase-T/Audio Visual Application Varies
