10. Select an unused time slot for channel 1 using DIP switches SW10-1 through SW10-5. Each
active voice channel uses one 64 Kbps digital time slot within the multiplexer’s aggregate rate.
Set the time slot using direct binary coding as shown in Table 4. Refer to the multiplexer
manual for guidelines on time slot selection.
Note that selecting an invalid time slot will disable the module. In T1 systems, only time slots 1
through 24 are allowed. Time slot 24 is not available for a T1 system using fast reframing.
In E1 systems, time slots 1 through 31 are allowed, however, time slots 0 and 16 are reserved
and cannot be used. Time slot 30 is not available for an E1 system using fast reframing. Time
slot 31 is not available if inter-node communications (NMX) is used.
