DOCSIS Cable Modem and eRouter Testing in CDRouter

Published: Mar 15, 2017

---

The most straightforward way to test both Cable Modems and eRouters in the same test setup is with the CDRouter DOCSIS add-on. This allows CDRouter to directly simulate the DOCSIS provisioning steps, including:

• Assignment of a management IP to the Cable Modem via DHCP
• Assignment of a routing IP to the eRouter via DHCP
• Transmission of custom DOCSIS configuration files via TFTP, which can be created as part of CDRouter’s test configuration.
• Simulation of Time of Day, DNS, and other necessary services
• Configuration of TR-069 and/or SNMP services

Note: CDRouter DOCSIS still requires the use of a CMTS, best configured in bridge mode.
