HARDWARE AND SOFTWARE DETERMINATION

Traffic Considerations

To determine if traffic engineering calculations should be made for G1 or G3i, consider the follow-

ing (for G3r, traffic engineering will be done regardless):

YES NO

Will the number of busy-hour calls meet or exceed 7200

(G1) or 10,000 (G3i)?

1 -

Will the call activity be different than the balance of 36%

outgoing, 36% incoming, 28% intra-premises (± 10%)?

2 -

Will the trunk (all types) to terminal ratio exceed 50%?3 -

Is ARS requested with more than 425 terminals?4 -

Is DID with Message Center Service requested and are

there more than 425 terminals?

5 -

Will more than 50% of the incoming traffic be handled by

the Attendant?

6 -

Will AUDIX be used?7 -

Will DCS or ISDN-PRI be used?8 -

In most domestic locations, the DOSS/ATTOMS-CPS configurator must be used

for all DEFINITY G1 and G3 designs. Note carefully any configurator report

messages associated with the above items that are answered ‘‘yes.’’
