deliver the current time and date to the Customer Premises Equipment
(CPE).
For the CND to occur, the number of the calling subscriber must be
available at the destination exchange. The number must pass before the
number can appear at the MAP display.
The local exchange sends an ESTABLISH message to the AN with the
optional information element called Pulsed Signal: Initial Ring. This
message instructs the AN to send an initial ringing pattern to the terminal of
the called subscriber. When the AN receives this message, the AN applies a
ring burst of 300 ms to the terminal of the called subscriber. The AN sends
an ESTABLISH ACKNOWLEDGE message to the LE.
After the first ring burst is complete, the AN sends a SIGNAL message to
the LE. The message contains an optional information element called
Pulsed Signal: Pulse notification. When the LE receives this message, the
LE starts a timer. The LE uses the CLASS modem resource (CMR) circuit
card in the RSC-M to transfer DTMF call information to the AN. The LE
transfers the DTMF call information on a bearer channel.
The CLASS and custom calling features are:
