When you create a primary rate interface from a channelized E1 or channelized T1 interface, you can select all the slots for the PRI, or just a few of them, leaving the rest as ds- interfaces.
To configure a primary rate interface from a channelized T1 interface, include the partition statement at the [edit interfaces ct1-pim/0/port] hierarchy level with the timeslots statement and interface-type bc specified:
- [edit interfaces]
- ct1-pim/0/port {
- partition 1 timeslot 1-10 interface-type ds;
- partition 2 timeslot 11-24 interface-type pr;
- }
This configuration creates interfaces ds-pim/0/port:1 through pr-pim/0/port:2.
Use the same configuration to create interfaces on a channelized E1 interface by including the partition statement and options at the [edit interfaces ce1-pim/0/port] hierarchy level.
To configure channelized E1 interface properties, include the e1-options statement at the [edit interfaces interface-name] hierarchy level:
- [edit interfaces interface-name]
-
e1-options {
-
fcs (16 | 32);
-
framing (g704 | g704-no-crc4
| unframed);
-
idle-cycle-flag (flags | ones);
-
loopback (local | remote);
-
start-end-flag (filler | shared);
- }
To specify options for each of the DS0 channels, include the ds0-options statement at the [edit interfaces interface-name] hierarchy level:
- [edit interfaces interface-name]
- ds0-options {
-
byte-encoding (nx56 | nx64);
-
fcs (16 | 32);
-
idle-cycle-flag (flags | ones);
-
loopback payload;
-
start-end-flag (filler | shared);
- }
