# Reference Model Class: TEL.PERSON
As ISO 21090, a constraint of TEL so that it must refer to a method of communication with a person. This data type flavor supports the logical representation of the PDS PERSON_TELECOM class which is used to contain data for a single telecom address, i.e. phone number or e-mail address. Attributes use and validTime may be used to represent equivalent attributes within the PERSON_TELECOM class. ## Specializes ## TEL ## Attributes
Name | Data type | Occurs | Description
--- | --- | --- | ---
value | Uri | 1..1 | As specified by ISO 21090, a Uniform Resource Identifier (URI) specified according to IETF RFC 2396 and constrained to a URL specified according to IETF RFCs 1738 and 2806. The URI specifies the protocol and the contact point defined by that protocol for the resource.
use | TelecommunicationAddressUse | 0..* | As ISO 21090, one or more codes advising a system or user which telecommunication address in a set of like addresses to select for a given telecommunication need. A telecommunication address may have a number of specified uses, e.g. home and work telephone number.
useablePeriod | QSET_TS | 0..1 | As ISO 21090, the periods of time during which the telecommunication address can be used. For a telephone number, this may indicate the time of day during which the party can be reached on that number. For a web address, it may specify a time range in which the web content is promised to be available under the given address. Note that this attribute does not specify the overall period of validity of the telecommunication address. A valid telephone number, for example, might still only be useable during certain periods, e.g. week days between 09:00AM and 5:00PM.
