Line Card Operation
After the line card detects the CPE and completes the initialization sequence, it configures itself for one
of the following types of operation

Cisco NI-2 Network Interface Processor Module Functions
After a reset, the NI-2 network interface processor executes boot Flash EPROM routines. Boot flash
code also contains the serial management bus (SMB) boot loader. The NI-2 network interface processor
module sends each line card its run-time image over the SMB and loads the main executable code into
SRAM. After the main-code image loads and runs, the line card loads its serial data bus (SDB) Utopia
field programmable gate array (FPGA) and initializes all modems.
ATM Virtual Circuit Support
Each line card supports up to 256 virtual channel identifiers (VCIs) and virtual path identifiers (VPIs)
per port. Each line card also enables use of default VPI/VCI mapping or provisioning of
VPI/VCI mapping by means of Cisco IOS configuration commands.
Configuring Software for a Line Card
For Cisco IOS software configuration information and support, refer to the Configuration Guide for
Cisco 6000 Family DSLAMs with NI-2 and to the Command Reference for Cisco 6000 Family DSLAMs
with NI-2 in the Cisco IOS software configuration documentation set that corresponds with the software
release installed on your Cisco 6260 NI-2 DSLAM hardware.
