Introduction
This AT&T Small Business System is expandable to a 16-extension telephone 
system. The 1080 telephone is compatible with 1070 and 1040 telephones. 
For details, see the Installation Guide. This system is not compatible with any 
other AT&T 4-line small business telephones, except for the 1070 and 1040 
telephones. 
The 1080 telephone is hearing-aid compatible and can be connected to 
four incoming telephone lines. This telephone features a speakerphone for 
handsfree use and a headset jack compatible with most two-band 2.5mm 
headsets (sold separately). There are two additional ports, known as AUX jacks 
or data ports, available for connecting the telephone to another device such 
as a fax machine or modem.
The 1080 enables paging, intercom, and call transfers between system 
telephones and is capable of connecting three parties in the same conference 
call.
This telephone also features a 32-number one- and two-touch memory for 
faster dialing and has a directory that can store up to 200 additional numbers 
with names. 
This telephone has a caller ID feature that supports caller ID with call waiting 
service. (Caller ID services are subscriber services available from many local 
telephone companies for a fee.)
Your 1080 telephone also features a built-in digital answering system that can 
store approximately 60 minutes of messages, memos and conversations or 
a total of up to 99 messages. You can access the answering system from a 
remote non-system touch-tone telephone or from another system telephone.
This 1080 telephone is equipped to function as an Auto Attendant in a multi-
telephone system. An Auto Attendant telephone can pick up and redirect 
incoming calls to other extensions in your telephone system. You can assign 
more than one Auto Attendant for your telephone system. For details, see the 
Auto attendant operation section (pages 59-63).
The 1080 telephone is compatible with Centrex service. Centrex is a special 
subscriber service that might be available from your local telephone company 
for a fee. If you subscribe to Centrex service, refer to the Centrex operation 
section (page 88).
