Automatic Time Slot Assignment System Configuration and Operation
4.17 Automatic Time Slot Assignment
You can automatically assign time slots to voice (E&M, FXS, etc.) cards by using the
Configuration command in the System Main Screen. Figure 4-20 shows typical time slot
assignments from four E&M cards to an E1 WAN port. The Configuration option
automatically assigns the eight ports of E&M card 1 to time slots 1 through 8, seven ports of
E&M card 2 to time slots 9 through 15, and all eight ports of E&M card 3 to time slots 17
through 24. Time Slots 25 through 31 are similarly assigned to E&M card 4, ports 1 through
7. Time Slot 16 is not assigned to any E&M card ports because it is reserved for
channel-associated signaling (CAS) or common channel signaling (CCS) transmission on an
E1 line.
For a T1 WAN port, the configuration command would assign time slots 1 through 8 to the
eight ports of the first E&M card. Time Slots 9 through 16 would similarly go to the eight ports
of a second E&M card, and time slots 17 through 24 would go to a third E&M card.
Figure 4-20. Automatic Time Slot Assignment Example
To use the Configuration command, first proceed as follows:
1. Make sure all voice cards you intend to configure are of the same type.
2. Place the cursor on the first user card slot that will have a card. In Figure 4-21, slots U5
through U8 will be assigned to 30 time slots on the E1 WAN port.
3. Press “
c”
to begin the configuration process.
4. Select the type of voice card from the types listed above the bottom line of the screen,
as shown in Figure 4-21. In that screen,
e&m-6
is chosen as the card type (E&M, 600
ohms).
