The TX Matrix Plus router TXP-4 configuration consists of one routing matrix switch
fabric with five data switching planes. One of the five data switching planes acts as a
backup
spare
to the remaining data switching planes. If faults are detected in an active
data switching plane, the plane is taken offline, and the backup
online. When a failed component is replaced and brought online, the data switching plane
in which it resides becomes the new backup
Each data switching plane consists of one or two TXP-F13 SIBs connected to four TXP-F2S
SIBs thorough the midplane. Table 21 on page 62 shows these connections.
The TXP-F13 SIBs on the TX Matrix Plus router and the TXP-T1600 SIBs on the T1600
router are connected by high-speed optical links within fiber-optic array cables. The
switch fabric uses ASICs to perform high-speed packet forwarding between the T1600
routers.
A packet that enters an interface on a PIC in a T1600 router and is destined for another
T1600 router in the routing matrix is first forwarded to a Packet Forwarding Engine on
the source router. The packet is then forwarded through the Packet Forwarding Engine
