PA-T3 and PA-2T3 Serial Port Adapters 1
PA-T3 and PA-2T3 Serial
Port Adapters
Description
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.
Platforms
This feature is supported on these platforms:
Cisco 7200 series
Cisco 7500 series
Cisco 7000 series routers with the RSP7000 and RSP7000CI
