Port Adapter Overview
The PA-T3+ port adapter provide a full-duplex operation at T3 (45 Mbps) speed. They support both
16- and 32-bit cyclic redundancy checks (CRCs); the default is 16-bit CRCs. You can change the default
setting with software commands.
The one-port PA-T3+(=), shown in Figure 1-1, provides up to two network interfaces per Catalyst 6000
family FlexWAN module in the Catalyst 6000 family switches. The two-port PA-2T3+(=), shown in
Figure 1-2, provides up to four network interfaces per Catalyst 6000 family FlexWAN module in the
Catalyst 6000 family switches.
The Cisco 7000 series router and the Cisco 7500 series router accept the VIP. You can install either one
or two PA-T3+ or PA-2T3+ port adapters per VIP. The PA-T3+(=) is a one-interface version, shown in
Figure 1-1, and the PA-2T3+(=) is a two-interface version, shown in Figure 1-2.
The Cisco 7304 PCI Port Adapter Carrier Card, which installs into the Cisco 7304 router module slots
2 through 5, accepts one PA-T3+ or PA-2T3+ port adapter. This provides one or two network interfaces,
respectively, per Cisco 7304 PCI Port Adapter Carrier Card.
See the Cisco 7200 Series Port Adapter Hardware Configuration Guidelines for information on the
number of PA-T3+ port adapters you can install in a Cisco 7200 series router.
The PA-T3+ port adapters can be installed in the single port adapter port of the Cisco 7301 router or the
Cisco 7401ASR router.
