Configure PA-E3 and PA-2E3 Serial Port Adapters
IC-92
Cisco IOS Interface Configuration Guide
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
The PA-E3 port adapter supports a subset of RFC 1407 MIB. We support DS3 Near End Group
including—DS3/E3 Configuration Table, DS3/E3 Current Table, DS3/E3 Interval Table, and
DS3/E3 Total Table. We do not support DS3 Far End Group and DS3/E3 Fractional Group. The
PA-E3 port adapter also supports the Card Table in the Cisco Chassis MIB and the MIB-2 for each
PA-E3 interface.
Note For additional information on E3 serial port adapter, refer to the PA-E3 Serial Port Adapter
Installation and Configuration publication.
PA-E3 and PA-2E3 Serial Port Adapter Configuration Task List
Perform the tasks in the following sections to configure the PA-E3. The first task is required; all other
tasks are optional:
Configure the PA-E3 Port Adapter
Troubleshoot the PA-E3 Port Adapter
Monitor and Maintain the PA-E3 Port Adapter
For PA-E3 port adapter configuration examples, see the “PA-E3 Serial Port Adapter Configuration
Example” section, later in this chapter.
Configure the PA-E3 Port Adapter
The commands listed in Table 7 have been added to support the PA-E3 interface configuration.
If you do not modify the configuration of the PA-E3, the configuration defaults shown in Table 7 are
used.
