Time Slot Allocation - Philips Sopho 2000 IPS User Manual

TIME SLOT ALLOCATION

On each DTI card, the system recognizes the lowest and highest channel numbers to which trunk numbers
have been assigned, and allocates time slots to all the channels between them. If trunk numbers are not
assigned to consecutive channels, the system allocates time slots to channels not assigned.
For example, as shown below, even when Channel 1 through Channel 10 have been assigned by the system
data programming (CM07 Y=01) except for Channel 5, the system allocates a total of 10 time slots for all
ten channels. Therefore, to avoid unnecessary allocation of time slots, it is recommended that consecutive
channels be assigned on each DTI card.
