After configuring the new interface, you can display its status. To show current status of the E3
interface on the PA-E3 port adapter, use any of the following commands in EXEC mode:
Configure PA-T3 and PA-2T3 Serial Port Adapters
The PA-T3 and PA-2T3 serial port adapters are available on Cisco 7200 series routers, on
second-generation Versatile Interface Processor (VIP2) in all 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-T3) or two (PA-2T3) high-speed,
full-duplex, synchronous serial T3 interfaces and integrated data service unit (DSU) functionality.
The T3 port adapters can transmit and receive data at T3 rates of up to 45 Mbps and use a 75-ohm
coaxial cable available from Cisco to connect to a serial T3 network. These port adapters support the
following features:
• 16- and 32-bit cyclic redundancy checks (CRC)
• High-speed HDLC data
• C-bit, M13, and bypass framing
• HDB3 line coding
• ATM-DXI, Frame Relay, HDLC, PPP, and SMDS serial encapsulation
• DS3 MIB (RFC 1407)
• Scrambling and reduced bandwidth
• Remote and local loopbacks
Note For additional information on interoperability guidelines for T3 serial port adapter DSUs,
refer to the PA-T3 Serial Port Adapter Installation and Configuration publication.
