For IT Providers: 

NAM Information

The NAM (Network Access Module) is the term CR uses to describe the place where you plug in your telephone or FAX machine to get a dial tone. Most NAMs are rectangular and an ivory color. The five-digit number written on the NAM is called the NAM number and must be included on all service requests in the space marked NAM. If a NAM is not available, you should include a floorplan/drawing of the building and room where you would like a new NAM installed. If you also need a Data NAM installed at this location, your ATR must complete the online New Data NAM Form and submit your order. Please provide a NAM number which appears nearest the port you will use to plug in your telephone or FAX machine. A wall NAM is a flat silver plate on the wall with only one port. If you are ordering a wall telephone you must use a wall NAM.

NCOS - Network Class of Service

The Network Class of Service (NCOS) determines the dialing-out access of each telephone and FAX line. The five levels of service are numbered, and the geographical regions covered by each of the NCOS levels are listed on the front of the form. NCOS 52 (Worldwide day/NCOS 2 night) allows you to protect lines from unauthorized calls after normal university business hours by allowing worldwide dialing-out access during the business day and restricting calls to Davis, Dixon and Woodland (NCOS 2 area) when the office is closed.
