Hierarchy Level

Release Information

Statement introduced before Junos OS Release 7.4.


For E1 and T1interfaces, allocate the specific time slots by number.


When configuring E1 or T1 interfaces on the 10-port Channelized E1/T1 IQE PIC, the timeslots statement must be included at the [edit interfaces e1-fpc/pic/port] or [edit interfaces t1-fpc/pic/port] hierarchy level as appropriate.


time-slot-range—Actual time slot numbers allocated:

Range: Ranges vary by interface type and configuration option as follows:

  • 1 through 24 for T1 interfaces (0 is reserved)

  • 1 through 31 for 4-port E1 PICs (0 is reserved)

  • 1 through 31 for NxDS0 interfaces (0 is reserved)

  • 2 through 32 for 10-port Channelized E1 and 10-port Channelized E1 IQ PICs (1 is reserved)

  • 2 through 32 for the setting under e1-options with IQE PICs (1 is reserved) (when creating fractional E1)

  • 1 through 31 for the setting under partition with IQE PICs (0 is reserved) (when creating NxDS0)


When creating fractional E1 interfaces only, if you connect a 4-port E1 PIC interface to a device that uses time slot numbering from 2 through 32, you must subtract 1 from the configured number of time slots.
