INSTALLATION TEST PROCEDURE

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 5-4.
