Note 1: Ringing cadence applies to the AMC. The ringing cadence is setup
using the ringing and silence signals. Following the answer, to reach the talking

Note 2: To clear a call, a disconnect clear signal is sent for 480 ms followed by
a clear forward. The line is not reused until an idle code is received from the AMC.

DC5 to BTUP and BTUP to DC5 signaling

This section illustrates the signaling procedures used during DC5 to BTUP,
and BTUP to DC5 calls. The BTUP trunk indicated is not connected between
the originating and terminating offices. The incoming and outgoing protocols,
DC5A or DC5ADD, are not the same.
The following figures refer to the DC5 signals by name. Refer to the figure
"DC5 and DC5ADD", incoming signals in this section for the DC5 incoming
signal codes. Refer to the figure "DC5 and DC5ADD", outgoing signals in this
section for the DC5 outgoing codes. Descriptions of the call processing events
follow each figure.
Timers for all DC5 and BTUP connection signal diagrams are designated by
the symbol T(n). To differentiate between the BTUP T1 timer and the DC5 T1
timer, the BTUP timer appears as T1'. Refer to the section on timers in this
section for more information.
