The general formula that is used to determine the expanded inbound and outbound CUR entries in Table 32 is:

Inbound CUR to stations of type t in Site j over PSTN trunks in Site i

Outbound CUR from stations of type t in Site i over PSTN trunks in Site j

	t		⎛inbound CUR from trunks in Site i ⎞
=	fj	⋅	⎝	to stations in Site j	⎠
	t		⎛outbound CUR from stations in Site i ⎞
=	fi	⋅	⎝	to trunks in Site	j	⎠

where:

●“Type t” refers to IP or circuit-switched

●fi t

●fj t

= number of type t stations in Site i

---------------------------------------------------------------------------------

total number of stations in Site i

= number of type t stations in Site j

---------------------------------------------------------------------------------

total number of stations in Site j
