Path and Port Numbering 69

Path and Port	The following tables outline the default port and path numbering for the
Numbering	SuperStack II bridge/router.
	Although the WAN connector on the model 5xx bridge/router is in a
	different physical location than the WAN connector on the model 4xx
	bridge/router, its path numbering is the same.
	Table 14 Path and Port Numbering for Model 43x , 44x, 53x, and 54x
	Bridge/Routers
	Path No.	Connector Mapped To	Port No. Mapped To
	1	L1	1
	2	L2	2
	3.1*	WAN	3
	3.2	WAN	4
	4	Serial A	5
	5	Serial B	6
	6	Serial C (model 5xx only)	7
	7	Serial D (model 5xx only)	8

*For built-in ISDN ports, the path numbering convention differs from the convention on a non-ISDN port. Instead of numbering only the physical interface or connector, such as path 3, ISDN sometimes requires that you number the connector and the multiple channels that transmit data (path 3.n).
