Port Adapter Overview
The PA-8T-232, shown in
for Catalyst 5000 family switches (that use the Catalyst RSM/VIP2), Catalyst 6000 family switches (that
use the Catalyst 6000 family FlexWAN module), Cisco 7000 series and Cisco 7500 series routers (that
use the VIP), Cisco 7100 series routers, Cisco uBR7200 series routers, Cisco 7301 routers, Cisco 7304
routers (that use the Cisco 7304 PCI Port Adapter Carrier Card), and Cisco 7401ASR routers. The
EIA/TIA-232 interfaces provide a direct connection between the high-speed bus in the router and
external networks. Each EIA/TIA-232 interface provides full-duplex (FDX) operation at the rate of
64 kilobytes per second (kbps). The EIA/TIA-232 interface is most commonly used in the United States.
Figure 1-1
All eight interfaces connect to the external networks through a single port that has a 200-pin, D-shell
receptacle. You must use an EIA/TIA-232 compact serial cable to connect interfaces to an external data
service unit (DSU) or channel service unit (CSU). The compact serial cable attached to the single
receptacle determines the mode (DCE or DTE) for all eight interfaces.
