Processor Port Network Cabinet
The PPN cabinet, pictured above, is the primary cabinet in all G3r systems. It
contains the Switch Processing Element (SPE) that controls the system and one
Port Network that is interconnected by the daisy-chained TDM/LAN bus. If the
system has a CSS, the PPN cabinet also contains a switch node. The individual
carriers are described in following sections.
The A position always contains a PPN Control Carrier (J58890AP), also known as
the Processor Carrier, which holds the SPE circuit packs. If the system has a
duplicated SPE, the B position holds a second PPN Control Carrier. At least one,
and up to four, Port Carriers (J58890BB) can be located in the other four carrier
positions, depending on traffic needs and whether the system uses those
positions for other types of carriers. In general, Port Carriers are added in the
sequence, B-C-D-E, unless those positions are used otherwise, as follows.
