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
