Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Evidence of ability to:

design and implement infrastructure for enterprise voice over internet protocol (VoIP) and unified communications (UC) systems to meet business requirements using converged networks

evaluate network traffic protocols and bandwidth considerations

configure a UC network

assess performance of convergent networks

test and verify security access levels.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.

To complete the unit requirements safely and effectively, the individual must:

compare session initiation protocol (SIP), H.323 protocol and media gateway control protocol (MGCP) or media gateway control (Megaco)

define latency, jitter and wander, and implement methods for reducing or eliminating them using jitter buffer, quality of service (QoS), traffic shaping and virtual local area networks (VLANs)

describe the format of a SIP uniform resource identifier (URI)

evaluate and implement SIP trunking to connect enterprise internet protocol (IP)-based communications systems over long distances

identify common G.7xx codes and describe the impact of compression on voice quality

define components of SIP

examine functions of signalling protocols for converged networks

summarise the following:

the client business domain, business function and organisation

current and emerging industry accepted hardware and software products

current and emerging transmission technologies and protocols
