    Example: Configuring Complementary Clock Sources on Channelized Interfaces

    This example shows how to configure complementary clock sources on channelized interfaces.

    Requirements

    No special configuration beyond device initialization is required before configuring this feature.

    Overview

    J Series devices connected to one another must have complementary clock sources configured. In the following examples, device R1 is connected to devices R2 and R3. Port 0 on the channelized T1/E1/ISDN PRI PIM of R1 is connected to R2, and port 1 is connected to R3. The drop-and-insert feature is configured on R1 to insert input coming from R2 on port 0 into port 1 for transmission to R3.

    Devices R1, R2, and R3 can be configured in three ways, depending on whether the drop-and-insert clock source on R1 is the external clock for port 0, the external clock for port 1, or the device's internal clock.

    Configuration

    CLI Quick Configuration

    To quickly configure this example, copy the following commands, paste them into a text file, remove any line breaks, change any details necessary to match your network configuration, and then copy and paste the commands into the CLI at the [edit] hierarchy level.

    Step-by-Step Procedure

    The following example requires you to navigate various levels in the configuration hierarchy. For instructions on how to do that, see Using the CLI Editor in Configuration Mode.

    To configure the drop-and-insert interfaces on device R1 to use the external clock for port 0:

    1. Configure device R2.
      [edit interfaces]user@host# set ct1-6/0/0 partition 1 timeslots 1-10user@host# set ct1-6/0/0 partition 1 interface-type dsuser@host# set ds-6/0/0:1 unit 0 family inet address 10.46.46.1/30
    2. Configure device R3.
      [edit interfaces]user@host# set ct1-3/0/0 clocking externaluser@host# set ct1-3/0/0 partition 1 timeslots 1-10user@host# set ct1-3/0/0 partition 1 interface-type dsuser@host# set ds-3/0/0:1 unit 0 family inet address 10.46.46.2/30
    3. Configure device R1.
      [edit interfaces]user@host# set ct1-3/0/0 clocking externaluser@host# set ct1-3/0/0 partition 1 timeslots 1-10user@host# set ct1-3/0/0 partition 1 interface-type dsuser@host# set ds-3/0/0:1 data-input interface ds-3/0/1:1user@host# set ct1-3/0/1 clocking external interface ct1-3/0/0user@host# set ct1-3/0/1 partition 1 timeslots 1-10user@host# set ct1-3/0/1 partition 1 interface-type ds

    Results

    From configuration mode, confirm your configuration by entering the show interfaces command. If the output does not display the intended configuration, repeat the configuration instructions in this example to correct it.

    For device R2[edit]user@host# show interfaces ct1-6/0/0 {partition 1 timeslots 1-10 interface-type ds;}ds-6/0/0:1 {unit 0 {family inet {address 10.46.46.1/30;}}}For device R3[edit]user@host# show interfaces ct1-3/0/0 {clocking external;partition 1 timeslots 1-10 interface-type ds;}ds-3/0/0:1 {unit 0 {family inet {address 10.46.46.2/30;}}}For device R1[edit]user@host# show interfaces ct1-3/0/0 {clocking external;partition 1 timeslots 1-10 interface-type ds;}ds-3/0/0:1 {data-input {interface ds-3/0/1:1;}}ct1-3/0/1 {clocking external interface ct1-3/0/0;partition 1 timeslots 1-10 interface-type ds;}
