4.2 Time Slot Mapping Benefits
By designing maps with different configurations, you can manage the traffic on your T1 lines to
●
Utilize bandwidth efficiently
●
Reduce transmission costs.
You can employ time slot mapping for
●
Time of day routing (switching to another map when traffic volume changes during peak hours)
●
Emergency routing (for backup protection and switching in the event of failures)
●
Loopback testing
●
Priority and non-priority routing (critical traffic not interrupted in event of a failure)
●
Cost cutting
In addition, you can later use any underutilized time slots as your operations expand.
One example of cutting the cost of leased T1 lines is to employ time slots so that you use fewer T1
lines (Figure 4-1). Suppose that Station WXYC is broadcasting music and video on two separate T1
lines to two receiving stations, using a total of four T1 lines. They could cut their costs in half by using
only two T1 lines by combining the music and video in different time slots on one frame. They would
be sending the same transmissions to the two stations on two T1 lines instead of four. Figure 4-1
shows that time slots 9 to 24 would remain available for future use.
