CMTS Embedded Code
Two separate codes are stored in the CMTS. The first code stored in the CMTS is the
CMTS Boot Code. This code tells the CMTS how to boot and how to utilize the TFTP
protocol. The second code is the runtime code that provides the CMTS with its
functionality. There are two files that are stored in the CMTS:
ram.hex
: CMTS runtime code.
nsu.fdp
: Modem runtime code.
