Specifications

P/N: PA-2E3
Cisco PA-2E3 Serial Port Adapter Feature Module

The PA-E3 and PA-2E3 serial port adapters are available on Cisco 7200 series routers, on Cisco 7500 series routers, and on Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI). These port adapters provide one (PA-E3) or two (PA-2E3) high-speed full-duplex synchronous serial E3 interfaces and integrated data service unit (DSU) functionality.

The E3 port adapters can transmit and receive data at E3 rates of up to 34 Mbps and use a 75-ohm coaxial cable available from Cisco to connect to a serial E3 network. These port adapters support the following:

•16- and 32-bit cyclic redundancy checks (CRC)

•High-speed HDLC data

•G.751 framing or bypass

•HDB3 line coding

•ATM-DXI, Frame Relay, HDLC, PPP, and SMDS serial encapsulation

•National service bits

•E3 MIB (RFC 1407)

•Scrambling and reduced bandwidth

•Remote and local loopbacks
