Distributed PKT-INTs
In earlier G3r systems, every PKT-INT resided in the PPN and terminated all of
the LAP-D links. In S8700 Multi-Connect, LAP-D links are terminated by the
PKT-INTs within IPSIs that are distributed out to the PNs. Whereas, G3r allowed
up to three active and three standby PKT-INTs in the PPN, S8700 Multi-Connect
allows one active and one standby PKT-INT in each PN (that is, up to 64 (for ATM
PNC) or 44 (for CSS PNC) active PKT-INTs in the system). As shown in
, EPNs 1 and 2 have IPSIs that terminate LAP-D links. EPNs 3 and 4 do not
have local IPSIs, so their LAP-D links are terminated by IPSIs in EPNs 1 and 2,
respectively.
