Table 44: Ranges For Channelized Ds3-To-Ds0 Configuration - Juniper JUNOS 10.1 - CONFIGURATION GUIDE 1-2010 Configuration Manual

By default, all the time slots are used. To configure the channel groups and time slots
for a channelized DS3-to-DS0 interface, include the
statements at the [edit chassis fpc slot-number pic pic-number ct3 port port-number t1
hierarchy level:
link-number]
[edit chassis fpc slot-number pic pic-number ct3 port port-number t1 link-number ]
channel-group group-number;
timeslots time-slot-range;
NOTE: If you commit the interface name but do not include the
configuration, the channelized DS3-to-DS0 interface behaves like a channelized
DS3-to-DS1 interface: none of the DS0 functionality is accessible.
Table 44 on page 493 shows the ranges you can specify for each of the elements in
the preceding configuration.

Item
FPC slot
PIC slot
Port
T1 link
DS0 channel group
Time slot
NOTE: The FPC slot range depends on the router. For a routing matrix, the range is
from 0 through 31. For M40, M40e, M160, M320, M120, and other T Series routers,
the range is from 0 through 7. For M20 routers, the range is from 0 through 3. For
M10 and M10i routers the range is from 0 through 1. For M5 and M7i routers, the
only applicable value is 0.
Bandwidth limitations restrict the interface to a maximum of 128 channel groups
per T3 port, rather than the theoretical maximum of 8 * 28 = 224.
There are 24 time slots on a T1 interface. You can designate any combination of
time slots. To configure ranges, use hyphens. To configure discontinuous time slots,
use commas. Do not include spaces. You can use each time slot number on only one
channel group within the same T1 link.
To configure channelized DS3-to-DS0 interface properties, you can include the
t3-options , t1-options , and
