OLU gateway information vector

The OLU gateway information vector (GIV) provides the gateway NCP name and CoS names for the gateway in the direction of the origin LU. This word of the parameter list is set to 0 if the session management exit routine is scheduled in the origin LU's network, because there is no such gateway NCP.

The format of the OLU gateway information vector is shown in Table 1. Its format is the same as that of the DLU gateway information vector.

Table 1. Format of OLU gateway information vector
	Dec (Hex) Offset	Size (Bytes)	Description
	0 (0)	1	Length of vector data (excluding this field) Note: If one of the name fields does not exist (cannot be determined at the time the exit is called), the name's length field is set to zeros and the length field of the next name in the GIV vector immediately follows.
This is followed by the gateway node name:
	0 (0)	1	Length of gateway NCP name (m)
	1 (1)	m	Name of the gateway NCP in the direction of the origin LU
This is followed by a CoS name:
	0 (0)	1	Length of CoS name (n)
	1 (1)	n	CoS name for the network on the origin LU side of this gateway NCP
This is followed by another CoS name:
	0 (0)	1	Length of CoS name (p)
	1 (1)	p	CoS name for the network on the destination LU side of this gateway NCP
