JUNOS 10.1 Network Interfaces Configuration Guide
Configuring Fractional T1 Interfaces
By default, all the time slots on a channelized T1 interface are used. To configure a
fractional T1 interface on a Channelized OC12 IQE PIC, perform the following tasks:
1.
2.
For channelized T1 interfaces, the time-slot range is from 1 through 24. You can
designate any combination of time slots. To configure ranges, use hyphens. To
configure discontinuous time slots, use commas. Do not include spaces. For more
information, see "Configuring Fractional T1 Time Slots" on page 585.
Example: Configuring Fractional T1 Interfaces
Configure a fractional T1 interface that uses time slots 1 through 5 and 10:
For a full configuration example, see the JUNOS Feature Guide.
Configuring Channelized OC12/STM4 IQE Interfaces (SDH Mode)
The Channelized OC12 IQE PIC configured for SDH mode creates a single channelized
STM4 interface. You can configure this interface as unpartitioned using the
statement at the
SDH VC-4-4C interface, or you can partition it into the following OC slices:

Configuring Channelized OC12/STM4 IQE Interfaces (SDH Mode)
Configure a T1 interface. For more information, see "Configuring T1 Interfaces"
on page 418.
Configure the number of time slots allocated to the T1 interface by including the
statement at the
timeslots
hierarchy level:
[edit interfaces t1-fpc/pic/port<:channel> t1-options]
timeslots time-slot-range;
[edit interfaces coc12-0/0/0]
partition 1 oc-slice 1 interface-type coc1;
[edit interfaces coc1-0/0/0:1]
partition 1 interface-type t1;
[edit interfaces t1-0/0/0:1:1 t1-options]
timeslots 1-5,10;
[edit interfaces cstm4-fpc/pic/port]
SDH virtual concatenation 4 (VC-4) and channelized AU-4 interfaces (4 interfaces,
any combination)
E3 interfaces from a channelized AU-4 interface (3 interfaces, any combination)
Channelized E1 or E1 interfaces from a channelized AU-4 interface (63 interfaces,
any combination)
NxDS0 interfaces from a channelized E1 interface
