Refer to the OPTN data of ➅

➅ OPTN data					b0-b3: OPTN data Note
b7	b3	b2	b1	b0

Note: This data displays when the Tenant No. of the calling station is larger than 15, and bit7 of ➄ displays as “1” (otherwise, “0” displays at any time). While the four-bit data of ➄ is self-sufficient in verifying the Tenant No. “1-15,” this OPTN data provides a supportive role to cover the larger Tenant No. ranging from 16 to 255. Use the following method to analyze the data:

Tenant No. of Calling Station (1-15)	=		0	0	0	0	Tenant No.
		OPTN data (0: fixed)					bit 0 - bit 3 of ➄
Tenant No. of Calling Station (16-255)	=			OPTN data			Tenant No.
		OPTN data (variable)					bit 0 - bit 3 of ➄

➆OG route number (Hex.)
