➂ OPRT data					b0-b3: OPRT data Note
b7	b3	b2	b1	b0

Note: This data displays when the IC Route No. is larger than 63, and bit6 of ➁ displays as “1” (otherwise, “1” displays at any time). While the six-bit data of ➁ is self-sufficient in verifying the Route No. “1- 63,” this OPRT data provides a supportive role to cover the Route No., which is larger than 63. Use the following method to analyze the data:

IC Route No. (1-63)

IC Route No. (64 or larger)

➃- ➄Trunk No. of IC trunk

b7 b6 b5 b4 b3 b2 b1 b0

➅Not used

➆OG route number (Hex.)

b7 b6 b5 b4 b3 b2 b1 b0

=		0	0	0	0	IC Route No.
	OPRT data (0:fixed)					bit0 - bit5 of ➁
=			OPRT data			IC Route No.
	OPRT data (variable)					bit0 - bit5 of ➁

b0-b7: Trunk No. of IC trunk

b7:	AC data
	0/1=Internal trunk/External trunk
b6:	OP data (0/1)
	When OPRT data of ➇ is valid, “1” displays,
b0-b5: OG route number
	• bit 6=0	Route No.<64	Refer to the OPTN
	• bit 6=1	<63 Route No.	data of ➇
