Port Adapter Overview

The Cisco PA-8T-V.35, shown in Figure 1-1 on page 1-2, provides up to eight synchronous serial

interfaces for the chassis. The PA-8T-V.35 network interfaces provide a direct connection between the

high-speed bus in the router and external networks. Each PA-8T-V.35 interface provides full-duplex

(FDX) operation at T1 (1.544 Mbps) and E1 (2.048 Mbps) speeds. The V.35 interface is most commonly

used in the United States and throughout Europe.

All eight PA-8T-V.35 interfaces connect to external networks through a single port that has a 200-pin,

D-shell receptacle. You must use a V.35 compact serial cable to connect PA-8T-V.35 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.

Note Although the Cisco 7304 PCI Port Adapter Carrier Card in the Cisco 7304 router, Catalyst RSM/VIP2,

the Catalyst 6000 family FlexWAN module, and the VIP support online insertion and removal (OIR),

individual port adapters do not. To replace port adapters, you must first remove the Cisco 7304 PCI Port

Adapter Carrier Card in the Cisco 7304 router, the Catalyst RSM/VIP2, the Catalyst 6000 family

FlexWAN module, or the VIP from the chassis, and then replace port adapters as required.

Cisco 7100 series, Cisco 7200 series, Cisco uBR7200 series, Cisco 7301 routers, and Cisco 7401ASR

routers support OIR of all port adapter types.
