Introduction to the CS8500-t
Thank you for purchasing the CS8500-t. This product was designed for environments that have hearing-
impaired and non hearing-impaired users sharing the same phone line that want to save money by
avoiding multiple dedicated telephone line charges. The CS8500-t allows a TTY/TDD, fax, telephone and
answering machine to share one single telephone line.
The CS8500-t quickly directs incoming telephone calls to one of three appropriate destinations, typically a
TTY/TDD, facsimile machine or fax/modem, as well as a telephone and answering machine, or any other
telephone device that responds to a standard ring signal.

Basic Operation
The CS8500-t is flexible and easy to use. When a call is received by the CS8500-t, the call is answered
with a voice announcement for voice callers instructing them to hold while the call is being transferred.
After the CS 8500-t answers a call, it will give a voice announcement to the caller, “Please hold through
the tones, your call is being transferred.”
Next, the CS 8500-t will send the calling TTY a message that reads “ TYPE GA TO CONNECT.”
If the CS 8500-t does not detect a TTY tone from a calling TTY, the call will be transferred to the TAD
and PHONE ports on the CS 8500-t.
If the caller types GA after the TTY message, the CS 8500-t will send the message “PLEASE WAIT” to
the calling TTY and then transfers the call to the TTY port on the CS 8500-t.
The ring count to the TTY port is set to 25 rings.
Fax calls are detected by the CNG tone (CalliNG) and sent to the FAX port automatically. Non-CNG fax
calls are sent to ANS. MACHINE and Phone ports.
