MBX IP Description / Operations & Programming Guide
Keypad Facility
The ISDN Keypad Facility Information Element (IE) may enable the User to activate certain
ISDN services (ex., Off-Net Forward). To access this facility, the Station must be enabled and
have a Flex button programmed for {KEYPAD FACILITY}. When activated, the digits dialed by
a User are sent in the Keypad Facility IE instead of the Called Party Number IE.
CONDITIONS
- This feature can be activated or deactivated only after a CO Line (ISDN) is seized.
- Once activated, the system will continue to send dialed digits as Keypad Facility IE
messages regardless of ISDN messages; in the connected mode, DTMF tones are
not sent to the connected party, only the keypad message is sent.
- This feature may not be available in the specific ISDN or may be a subscription
service.
- The System can handle only a single Call Reference; services that require handling of
two simultaneous Call References, cannot be supported.
