ماژول شبکه سیسکو PA-8T-V.35

The Cisco Network module PA-8T-V.35, shown in Figure 1-1, 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
