PA-E3 and PA-2E3 Serial Port Adapter 1
PA-E3 and PA-2E3 Serial Port
Adapter
Description
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
Note For additional information on interoperability guidelines for E3 serial port adapter DSUs,
refer to the PA-E3 Serial Port Adapter Installation and Configuration publication.
Platforms
This feature is supported on these platforms:
Cisco 7200 series
Cisco 7500 series
Cisco 7000 series routers with the RSP7000 and RSP7000CI
