Troubleshooting EMTA Provisioning
Provisioning PacketCable Embedded Media Terminal Adapters (EMTAs) is a relatively complex
process; however, with the right tools and ‘tricks of the trade,’ getting EMTAs operational is a fairly
straightforward process.
This chapter assumes that the Cisco Network Registrar (CNR) and Broadband Access Center for Cable
(BACC) are both in use; however, much of the information would also apply for other deployments.
Basic knowledge of CNR (scopes, policies, basic DNS zone setup, and record entry) and BACC (class
of service, DHCP criteria, external files, and BACC directory structure) is also assumed.
For more information on the Cisco CNR, refer to
http://www.cisco.com/en/US/products/sw/netmgtsw/ps1982/prod_technical_documentation.html.
For more information on the BACC, refer to

Know The Basics
The PacketCable EMTA provisioning process consists of 25 steps, with several additional steps if secure
NCS call signaling is to be used. To troubleshoot EMTAs, knowledge of these 25 steps, or having the
‘cheat sheet’ from the PacketCable provisioning specification (see below) is absolutely essential.
The Architectural Elements
Before we get into the trpubleshooting of EMTAs, you should be familair with the following system
components as described in the subsections that follow.
• Embedded Media Terminal Adapter
• DHCP Server
• DNS Server
• Key Distribution Center
• PacketCable Provisioning Server
• Call Management Server
