Assignment of FCH Related Data

7.1Assignment of Access Code for Tandem Connection via FCCS - ACIS

For Release 3 or later software, tandem connection via FCCS - ACIS link can be established. Using LDM, appropriate routing data for each node can be assigned as shown in the following example.

Example of Fusion Network

	LGRT:200		LGRT:100	LGRT:300
		ACIS	ACIS	ACIS
	COT		COT	COT
		FCCS	FCCS
Node A		Node B	Node C	STN (C)
	STN (A)		STN (B)
(in "91202" area)		(in "91303" area)
		Logical route to be seized
Access code		STN (A)	STN (B)	STN (C)
			1st LGRT: 200	1st LGRT: 200
9-1-202		LGRT: 200		2nd LGRT: 100
			2nd LGRT: 100
				3rd LGRT: 300
		1st LGRT: 100		1st LGRT: 100
9-1-303			LGRT: 100	2nd LGRT: 200
	2nd LGRT: 200
				3rd LGRT: 300

Note: When the related data is assigned to DM, outgoing connection is available only for external routes in self node (i.e. FCCS - ACIS link cannot be established).

To initiate seizure of an external trunk, one of four methods - OGC, OGCA, LCR, LCRS - can be used (See the following sections).

7.1.1OGC

A procedure for assigning the OGC access code is explained using the following example.

Node B		Node A
	FCCS	LGRT:200	PSTN
		COT

1-202-345-6789

STN (B)

Station B dials￿ 9-1-202-345-6789
