Operation
Each NTCK16AX and NTCK16BX generic Central Office trunk card supports the following:
• Loop start operation
• Battery reversal detection
• Busy tone detection and supervision
• Loss Switching
• Trunk-to-Trunk connections
• Call Disconnect
In addition, the NTCK16AX circuit card supports internal 12/16 kHz PPM detection.
Loop start operation
Loop start operation is configured in software and is implemented in the card through software
download messages.
Idle state
In the idle state, the ringing detector is connected across the tip and ring wires, providing a
high impedance loop toward the Central Office.
Call placed by Central Office
The Central Office initiates a call by applying ringing between the tip and ring wires. If the call
is answered, the ringing detector on the trunk card is switched out and a low resistance dc loop
is placed between the tip and ring leads.
On trunks configured for battery supervision, the battery detector records the polarity of the tip
and ring wires and sends an answer acknowledge signal to software.
Call placed by CS 1000E, CS 1000M, and Meridian 1
To initiate a call, the CS 1000E, CS 1000M, and Meridian 1switches out the ringing detector
and places a low resistance loop across the tip and ring leads. On trunks configured for battery
supervision, the trunk card sends a seize acknowledge signal to software.
