Troubleshooting Basics

System knowledge and planning, supported by up-to-date documentation and communication, is the key

to maintaining a problem-free network environment, as well as to providing the ability to isolate and fix

a network fault quickly. This requires a framework of procedures and personnel to be in place long before

any network changes take place.

The Cisco BLISS for Cable solution supports connections to external switches and to internal

components, such as media gateway controllers, signal processors, and trunking gateways. Because the

Cisco BTS 10200 functions in a complex environment involving numerous connections, links, and

signaling protocols, when connectivity and performance problems occur, this troubleshooting guide can

help you isolate and resolve the most common connectivity and performance problems in your network

environment.

This section provides a broad look at the topics related to troubleshooting. These topics give you a frame

of reference for understanding the various components, interfaces, and tools you will work with when

troubleshooting the Cisco Broadband Local Integrated Services Solution.

This section introduces the following topics:

• Where to find information about hardware and software components

• Where to find architecture diagrams and call flows

• Communications protocols used between solution components
