Tier There are seven (7) possible tiers. Each tier can have its own durationinitial increment, subsequent increment, rate, mrc, and effective date. In practice, all tiers usually have the same own durationinitial increment, subsequent increment, rate, mrc, and effective date.
Duration Initial Increment This refers to the initial call duration measured in seconds. For rating purposes, all calls are rated the minimum durationinitial increment. For example, a 3-second call with a duration an initial increment of 6 seconds is billed for 6 seconds. A 42-second call with a duration an initial increment of 60 seconds is billed for a 60-second call.
Subsequent Increment This refers to the subsequent call duration increments beyond the initial duration. For example, a 100-second call with a duration initial increment and subsequent increment of 6 seconds is billed for 1 duration initial increment and 16 subsequent increments. A 10 min minute and 22-second call with a duration an initial increment and subsequent increment of 60 seconds is billed for 1 duration initial increment and 10 subsequent increments.
rate_minute The per minute rate
mrc - XXX
integrate This is the rate for an inter-LATA call (i.e. the calling number and the call number are in different LATAs). Calls between the US and Canada would be interrated calls. This rate only applies to Prefix Jurisdiction Rate Decks.
