If a coaxial interface is required, use NT5K85 in conjunction with the
NTBK05.
Channel associated signaling
Channel associated signaling means that each traffic carrying channel has
its own signaling channel permanently associated with it. Timeslot 16 is
used to transmit two types of signaling: supervisory and address.

Incoming signal
Functions of the NTAK10 with regard to incoming signaling include:
• recognizing valid changes
• determining which channels made the changes
• collecting PPM
• reporting changes to software

Outgoing supervisory signals
The desired ABCD bit pattern for a channel is output by the NTAK10, under
the control of the system controller card. The bit pattern to be transmitted
is held on the line for a minimum period of time. This time is specified in
the same message and ensures that the signal is detected correctly at
the far end.
