Introduction
This is the documentation of the DKTCOMEGA managed CPE product line.
The hardware consists of a switch with a fiber WAN port and 4 RJ45 LAN ports.
These ports are connected together with a powerful programmable layer 2 switch.
A CPU is attached to the switch. Initial the switch is setup only to accept traffic
between the CPU and the WAN port, first in the end of the CPU boot process are
the LAN ports enabled.
As an option a VoIP (SIP based) plug-in module can be installed, which will give 2x
RJ-11 analogue phone connections.
The CPE is provisioned via DHCP/TFTP, however also SNMP can be used to for
surveillance and settings.
Following DKTCOMEGA product codes are supported:
10/100 Mbps #79204, from now on referred to as 100Mb
100/1000 Mbps #79403, from now on referred to as 1Gb
10/100 Mbps w/ VoIP #79265
100/1000 Mbps w/ VoIP #79275
100/1000 Mbps w/ VoIP + Wifi #79550, special release only!
VoIP Plug-in module #65699, for now on referred to as VoIP

The boot process of the CPE node
The boot process is split in two:
-First the node issue a dhcp request with dhcp option 60 set to <file
name>vx_xx (where x_xx is the version number of the firmware).
-Afterwards the node start it's operation system (OS). The OS also issue a dhcp
request, with dhcp option 60 set to the version of the software.
When a new node is unpacked it doesn’t contain any firmware, and before it can
be used in must be updated with the latest revision. This mean that when the
node is installed at the customer premise, it will be required to remotely update
with firmware, before it will be working. It is highly recommended to visit
www.dktcomega.com -> support -> firmware for latest boot loader and firmware
revision.
The managed node depends on DHCP negotiation. Through this negotiation the
firmware ID of the managed node is exchanged for a configuration file. The DHCP
server hands out the configuration file depending on the firmware ID.
Bootstrap (Part of boot loader).
A small piece of code that is able to setup critical CPU specific registers such as
CPU clock, flash interface and SDRAM timing. The bootstrap code is automatically
loaded by the CPU into internal RAM of the CPU and executed. Bootstrap loads a
larger general boot-loader; U-boot.
U-boot (Part of boot loader).
This is a larger chunk of boot-loader software, which is able to setup network and
other more complex features of the CPU. U-boot use DHCP to get network setup.
U-boot is able to download firmware updates using TFTP.
Linux (Main Firmware).
This is the main software with full network support and features to use the
complete hardware platform. The network is configured using DHCP, and the
system configuration is downloaded using TFTP.
The first bootp/dhcp request from the device can be used to remote upgrade the
firmware. If a bootfile and a bootserver is given in the bootp response then the file
is downloaded via tftp and executed by the device.

The device is configured to not pass any traffic per default, so in order to pass
traffic through the switch engine, the switch --enable-lan command must be
provisioned to the device. Also telnet daemon must be started, with the use of
telnetd -l /bin/sh command in the script

DHCP Settings
The CPE requires a dhcp server connected to the fiber WAN port before power on.
As an example we have used Linux Kubunto platform and installed the following
component via adept
dhcp3
tftpd
Make sure that DHCP server has its unique static IP address settings, so it doesn’t
conflict with its own leasing of IP Addresses.
It is important that the DHCP server is properly configured, and that it responds to
the DHCP options requested by the CPE. Otherwise communication with the
internal CPU of the CPE can’t be obtained.
For more information about DHCP options in dhcp3, please refer to:
http://pwet.fr/man/linux/formats/dhcp_options
1) CPE requests in its BOOTLOADER discoverer:
Option: 53, 57, 60, 55
2) DHCP Server offers in it responses:
Option: 53, 54, 51, 1, 3

3) CPE requests in its LINUX Boot-up process, where configuration file is requested:
Option: 53, 61, 60, 50, 54, 55, 1, 3, 28, 66, 67
To edit DHCP Server Setup for dhcp3, edit the DHCP setup configuration file:
sudo kate /etc/dhcp3/dhcpd.conf
# DHCP SECTION: insert the following

To restart DHCP Server
Any change in the dchp configuration implies a server reset. For the
DHCP server used for this purpose the following instruction is
necessary:
sudo /etc/init.d/dhcp3-server restart
TFTP Settings
After the DHCP server is configured a TFTP server should be configured, so
firmware image and configuration file for the CPE can be downloaded correctly.
As an example we have used Linux tftpd and xinetd
The TFTP configuration file must be edited. And a tftpboot directory must be
created in root and made accessible from CPEs
mkdir tftpboot
