Table 44 is based on the assumption that the system already has basic
telephones, remote access, and tie trunks.
Table 44. System Requirements for TTRs
If one or more voice messaging systems are used, additional TTRs are needed
(see Table 45
).
Table 45. TTRs Required by Voice Messaging Systems/Auto Attendants
In Release 6.0 and later systems, when you program a calling group for Prompt-
Based Overflow, additional TTRs are required for primary and secondary delay
announcement devices (see Tables 46
and 47).
NOTE:
If no announcement is used on a primary or secondary delay
announcement device, no TTRs are needed.
* If a 12-port MERLIN LEGEND Enhanced Service Center is used,
8 TTRs are required.
