Table 46. TTRs Required for Primary Delay Announcement Devices When
Using Prompt-Based Overflow
Table 47. TTRs Required for Secondary Delay Announcement Devices
When Using Prompt-Based Overflow
Follow these steps to calculate the number of TTRs required by the system:
1. Total the TTRs needed for the volume of calls per hour (see Table 44
).
NOTE:
You must consider the call traffic across a private network when
estimating the number of required TTRs. This includes calls on
analog tandem tie trunks and T1-emulated tandem tie trunks. In
addition, if your private network includes Centralized Voice
Messaging, you must consider the call traffic coming across the
private network for the voice messaging system and the TTRs
required for the updating of Message Waiting lights (Release 6.1 or
later systems). For this updating, a TTR is required at the sending
end and the receiving end. If the systems in the private network are
connected by PRI trunks, no additional TTRs are needed.
