Dial Pulse Interdigit Time
You can set the interdigit time between dial pulses when the system pulse–dials a number over a line. The FXT
defaults this time to 200 milliseconds and provides a range of timing values in 100 millisecond intervals
between 100 milliseconds and one second.
Dial Pulse Rate—Make/Break Ratio
You can set the line make/break ratio for rotary dial signaling in a more flexible manner. You can program the
make and break times independently in one millisecond increments to any time from one to 99 milliseconds.
Dialed Number Identification Service (DNIS)
The DNIS feature allows the FXT to read an inband DTMF digit string sent by a common carrier. It uses this
information to identify the telephone number the caller dialed and appropriately route the call. DNIS is a service
that long distance carriers make available for dial 800 and dial 900 number subscribers on lines that use E&M
signaling over a E1 network. Also see the discussion titled Automatic Number Identification (ANI).
ANI/DNIS Enhancements
Installers can program an option to support the DTMF ANI / DNIS with two information digits. When they
enable this feature option, the format of the digit string changes from the SANISDNISS format to a format
that includes a two-digit code that indicates the presence of ANI digits (I ANI DNIS where I equals the
two-digit string). The ANI digit string indicates the calling party’s telephone number. The DNIS digit string
identifies the call destination station.
Also refer to the paragraphs titled Automatic Number Identification (ANI) and Automatic Pause Insertion.
Digit Q and Z Position
At default the system arranges for users to dial the 1 digit to represent both letters Q and Z; however, you can
take programming action to move the Q and Z letters to the 7 and 9 digits respectively. After programming, the
7 digit represents the letters PQRS and the 9 digit represents the letters WXYZ. This programming action places
the letters Q and Z in alphabetical sequence with the other letters in the alphabet. Some users find this
reprogrammed arrangement easier to use than the defaulted arrangement.
Digital Wireless Telephone Support
The FXT supports the operation of the Scout 900MX digital wireless telephone. The Scout 900MX is a
full-featured proprietary multiline telephone consisting of a wireless handset that lets the user roam about and
still make and receive telephone calls.
