Configuring PRI Interfaces

When you create a PRI 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 PRI 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 timeslots 1-10 interface-type ds;partition 2 timeslots 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);}
