Resource assessment

Answer the questions in the following table to determine if you have allocated sufficient resources

on the Business Communications Manager for IP telephony.

For information about changing the DS30 split for the Business Communications Manager and

allocating media resources, refer to the Programming Operations Guide (data sections).

Keycodes

All elements of VoIP trunks and IP telephony are locked by the Business Communications

Manager keycode system. You can purchase keycodes for the amount of access you want for your

system. Additional keycodes can be added later, providing there are adequate resources to handle

them.

3.g Has the estimated latency values between network locations been calculated?

3.h Have the Bandwidth/CIR utilization values for all WAN links been calculated?

3.i Has the quality of service availability on the network been calculated?

Table 4 Resource assessment

Prerequisites Yes No

4.a Has a Business Communications Manager Resource Assessment been performed using

the resource questionnaire in the Programming Operations Guide?

4.b Has an analysis been done to determine which DS-30 split is appropriate for the system?

Has the DS30 split been changed to 3/5, if necessary?

Table 5 Keycodes

Prerequisites Yes No

5.a Complete this question only if you are using VoIP trunks: Do you have enough VoIP

keycodes? Both H.323 trunks and SIP trunks use VoIP keycodes.

5.b Complete this question only if you are using IP telephones: Do you have enough IP client

keycodes? (Note: IP clients and IP telephones are a 1:1 ratio. Include any NetVision

telephones to your calculations. As soon as an IP telephone is registered, it occupies an IP

client, whether it is active or not.).
