2.1.5PAD Setting
When setting up a No.7 CCIS Network, PAD setting differs from that in the case of analog network.
(a)For an outgoing call to/incoming call from a Tie Line:
•Via “ARTD” command (CDN=30) or by switch setting on the circuit card (DTI/CCT).
(b)For a tandem Tie Line connection:
•Via “APAD” command or switch setting on the circuit card
<EXAMPLE>
At both the originating and terminating offices, 0 dB is set to the outgoing side and 8 dB is set to the terminating of the DTI/CCT route via “ARTD” command or switch settings.
At the tandem office, 0 dB is set for both the terminating and originating sides of each DTI/CCT route via “APAD” command.
This arrangement is shown in Figure
