Architecture 979
As the idle code and unequipped code can be country dependent, the
software instructs the NTBK50 to use different codes for each direction. The
32 digital pads available are illustrated in Table407 "Digital pad values and
offset allocations" (page 979). The values shown are attenuation levels
(1.0dB is 1 dB of loss and –1.0 dB is 1 dB of gain).

Signaling interface
The signaling interface consists of the A07 DS-30X signaling controller.
This interface provides an 8 Kbps signaling link via the DS-30X timeslot
zero data bit zero. Messages are 3 bytes in length.
The Meridian 1 signaling interface consists of the A07 DS-30X signaling
controller. This interface provides an 8 Kbps signaling link via the DS-30X
timeslot zero data bit zero. Messages are 3 bytes in length.
