Priority definitions

Priority can be deduced using a combination of Urgency and Impact. For reference, the definitions of these terms are as follows:

Impact:a measure of the business criticality of an Incident, often equal to the extent to which an incident leads to degradation of agreed service levels. Impact is often measured by the number of people or systems affected.

Urgency:the necessary speed of solving an incident of a certain impact. A high-impact incident does not, by default, have to be solved immediately.

Priority:is expected effort. This is denoted by a number value, and is determined through assessing a combination of impact and urgency.

The matrix below describes the framework for determining priority.

Urgency	High	1	1	2
	Medium	2	2	3
	Low	2	3	3

Details

NOTE: This is a deprecated service.

Dialup network allows you to connect to the University network with a dialup modem over a phone line.

We provide a toll-free 800 number to access the Columbia campus network from any remote U.S. location. Using a modem and a regular telephone line, you can connect to Columbia at bandwidth speeds of up to 56 Kbps.

Dial-up access is available to all Columbia faculty, students and staff through the CUIT Modem Pool. This is a free service, but you are responsible for any phone charges incurred when your computer calls our modem pool.

If you will be traveling and need to dialup from outside New York City, CUIT offers a national 1-800 dial-up service which will charge your account a set amount per minute.

Standard Service Features

The CUIT Dial-Up Modem Pool offers Columbia University affiliates the opportunity to connect to the campus network from a remote location using a modem and a phone line. The modem pool offers both terminal emulation service and Serial Line Internet Protocol (SLIP)/Point to Point Protocol (PPP) access. SLIP/PPP support allows users to run Web browsers such as Netscape or Internet Explorer.

Access to the modem pool is provided via several phone numbers. When calling the modem pool, please follow the connection guides provided below.

Standard Costs:

You don't have to worry about differing carriers or long-distance charges. (Please note that some hotels do charge a nominal fee for placing any data calls.)

There are no one-time or monthly charges for using this service. Although the call is made to a toll-free Columbia online service from anywhere in the US, there is a usage charge of 8.5 cents per minute billed to your Personal Security Code (PSC) account. Note: If you already have a PSC account, please request to have your 800 number access service activated.
