ADN
Additional Directory Number (ADN)
An ADN is an additional line on a phone. For an additional fee, An ADN can be added to any phone that has an available programmable button. Because this is a software-only line, there is no additional telephone equipment to purchase. By default, the ADN light will flash and the phone will ring when the ADN line is called; however, the user can program other ring options (see “Ring Options”).

Analog
An analog line is a generic circuit using analog waveform representation (as opposed to any number of proprietary digital signalling formats, including the Ericsson System in use at UMass) that supports standard analog telephones, answering machines, fax machines, modems, and telephone company analog lines.

Ethernet 10Mbps
Networked buildings on-campus have dedicated Ethernet jacks that make it possible for users to link their personal computers to the network. These connections are managed by OIT Network Services.

Ethernet 100Mbps
Networked buildings on-campus have dedicated Ethernet jacks that make it possible for users to link their personal computers to the network. These connections are managed by OIT Network Services. NOTE: Contact Customer Service to see if 100Mbps ethernet connections are available in your building.

Hunt Group
A Hunt Group involves setting up a departmental telephone number as a Hunt Group Pilot, which then distributs calls to group members sequentially or evenly. Additional fees apply.

Jack Number
Phone jacks are usually located on the wall at about 18" from the floor, but may also be found at counter-height or floor level. The standard jack has a faceplate with four ports and is labeled with a number such as "1-1-11". The top left port is wired for a phone or analog line and would be designated as "1-1-11A". The top right port is also wired for a phone or analog line and would be designated as "1-1-11B". The bottom right port is colored blue or orange. It is wired for data such as a private lan or ethernet connection and would be designated as "1-1-11D". The bottom left port on the faceplate is sometimes a blank. It can be wired for a phone, analog or data line and would be designated as "1-1-11C".

MDN
Multiple Directory Number (MDN) An MDN is a line that flashes and/or rings at multiple locations when it is called. For an additional fee, Any ODN or ADN may be programmed as an MDN on another phone that has an available programmable button. Because this is a software-only feature, there is no additional telephone equipment to purchase. By default, the MDN light will flash, but not ring when the line is called; however, the user can program other ring options (see "Ring Options").

ODN
Own Directory Number (ODN) The ODN is the primary number for the phone (the number printed under the handset).

One-Time Charges
One-Time Charges are billed for the one-time installation or activation of services and may include labor, instruments, and materials.

P.I. Signature
Principal Investigator (P.I.) Signature
The Principal Investigator is the person who has signature power on a Project or Grant Account.

Primary User
The Primary User name will appear on the main departmental listing of the monthly Telecom bill, and is essential for the police to help identify Emergency 911 callers. Any number of subsidiary user names can be listed under the Primary User name where individuals share a phone. In some cases where it is impossible to identify a person as the Primary User, a generic name such as a Department Office or Building and Room Number can be used.

Private LAN
Local Area Network (LAN)
Some departments or buildings might have their own private LANs connecting shared printers or servers with workstations. These connections are managed by the individual departments.

Recurring Monthly Charges
Recurring Monthly Charges are billed for the use of phone services as it accrues over time.

Special Circuit
Special Circuits are those circuits not directly associated with or originating from within the telecomunications or LAN/WAN systems, which include the telephone extensions and Ethernet network connections respectively. Special Circuits generally require separate transport via copper wire or fiber optic cable outside of these systems. Some typical examples of Special Circutis are: radio, alarm (for fire, burglary, intrusion, etc.) and point-to-point datacom circuits (UCard, Card Access, T-1, video, etc.)

Suspend or Unsuspend Phone Service
If you have a phone that will not be used for several months or more, you can store it away in a safe place and have the service for that phone suspended for an indeterminate amount of time. The cost to suspend service is $15.00. There is an additional $15.00 charge to unsuspend when you decide to put that phone back in use. Depending upon the monthly charge for the phone, it may be more economical to suspend it for a period of time rather than to deinstall and then install another phone later on. Due to the limited availability of Analog lines, Ethernet and Private LAN connections, these services cannot be suspended.

TAU
The TAU-2620 (Terminal Adapton Unit) is a digital device that works in conjunction with the UMass Telecommunications System (similar to a modem) to support data transmission, both on campus as well as off campus (through utilization of a modem pool). The actual installation of the TAU to the University Telecommunication System will be done by a telecommunication technician. However, the connection of the TAU to the computer is the responsibility of the user.

Hardware requirements include a Serial Interface Cable with a "male" 25-pin connector for the TAU. A DOS computer requires a 9-or 25-pin "female" connector to its serial port, and a MACIntosh computer requires an 8-pin mini-din "male" connector to connect to the MAC's serial port. A site licence for the appropriate software can be purchased from OIT Personal Computing Support Services. Information can be obtained from the OIT Help Desk at 545-9400.
