PA-8T-V35 Cisco 8-Port Synchronous Serial V.35 Port Adapter

The PA-8T-V35 is a Cisco 8-port synchronous serial V.35 port adapter, also written PA-8T-V.35, with a spare number of PA-8T-V35=. Each of its eight interfaces runs full-duplex at T1 (1.544 Mbps) and E1 (2.048 Mbps) speeds. All eight connect to external networks through a single 200-pin D-shell receptacle, and a V.35 compact serial cable joins them to an external DSU or CSU.

The cable attached to that one receptacle sets DCE or DTE mode for all eight interfaces. The DTE cable is CAB-OCT-V.35-MT, with a 34-pin Winchester V.35 plug, and the DCE cable is CAB-OCT-V.35-FC, with a 34-pin Winchester V.35 receptacle. Both are 6 feet (1.8 meters) long and split into eight 34-pin connectors at the network end. The ports support NRZ and NRZI formats and 16-bit and 32-bit CRCs, with NRZ and 16-bit CRC as the default.

Total bandwidth is 16 Mbps, which can be shared as 8 Mbps on two ports, 4 Mbps on four ports or 2 Mbps on eight ports, and the recommended maximum rate for V.35 is 2.048 Mbps, at a distance of 25 feet (8 meters). The faceplate has one status LED per port and an enabled (EN) LED. The adapter fits the Cisco 7100 series (slot 3 in the 7120 and slot 4 in the 7140), the 7200 series, the uBR7200 series, the 7301 and the 7401ASR, and also the Cisco 7304 PCI carrier card, VIP, Catalyst RSM/VIP2 and Catalyst 6000 FlexWAN module. Online insertion and removal works on the 7100, 7200, uBR7200, 7301 and 7401ASR routers. The router for the 7301 slot is the CISCO7301 Cisco 7301 router, and more WAN adapters are in Cisco interface cards.
