STEP 1: ASYD - Assign the following data.
SYS-1 Index 186 bit6=1 (ISDN/CCIS is in service)
187=00 Hex
220 bit6=0 (ISDN is in service)
STEP 2: Assign the numbering plan data for call origination.
STEP 3: ARTD - Assign the route data for Bch and Dch at each physical interface.
Note 1:Depending on the level diagram of the network. Data “4” is for standard.
Note 2:Note that each office...

STEP 4: ARTI - Assign the trunk application data.
INTD = 1 (IS-11572)
STEP 5: ATRK - Assign Bch trunks. Note that the LEN of Dch trunk should be assigned after STEP 9:
ACIC2 command assignment.
STEP 6: MBTK - Make idle Bch trunks.
STEP 7: ADPC - Assign PC (Point Code) for both Bch and Dch at each physical interface.
Note:Same PC (not existing PC for CCIS) must be assigned for both Bch and Dch....

Q-4 Q-SIG (CIRCUIT SWITCHED BASIC CALL - ETSI VERSION)
1. General Description
This feature enable NEC’s PBX to connect to NEC’s PBX or other manufacturer by using Layer 3 protocol for
the signaling for the support of circuit mode bearer services at the Q reference point.
Q-SIG conforms to ETS 300 172.
Note 1:ETS 300 172= Private Telecommunication Network (PTN);
Inter-exchange signaling protocol
Circuit mode basic...

Q-SIG (CIRCUIT SWITCHED BASIC CALL - ETSI VERSION)
1. Q reference point
The Q reference point is not expected to be a physical interface but is shown in conceptual terms in the figure
below.
The Q-Sig protocol creates Layer 3 messages for inter-PTN (PBX) signaling.

Note 1:When there is no called party number from ISDN, PBX may define the called party number.
Note 2:In the connection from Q-SIG to ISDN, PBX may add or delete digits of the called party number.
Note 3:A digital data communication between CCIS and Q-SIG will be disconnected by High Layer if the at-
tribution mismatch.
Note 4:CCIS in this section means CCIS without ISDN transmitting information...
