Configuring QL Values for SSM

Use the following syntax to configure the quality level (QL) values for Synchronization Status Messaging (SSM).

CLI Syntax:

config>system>sync-if-timing 
    abort
    begin
    external
        input-interface 
            impedance {high-impedance | 50-ohm | 75-ohm}
            no shutdown
            ql-override {prs | stu | st2 | tnc | st3e | st3 | smc | prc | ssu-a | ssu-b | sec | eec1 | eec2}
            type {2048khz-G703 | 5mhz | 10mhz}
    commit
    bits
        input
            [no] shutdown 
        interface-type {ds1[{esf|sf}] | e1[{pcm30crc | pcm31crc}] | 2048khz-G703}
        output
            line-length {110|220|330|440|550|660}
            [no] shutdown
        ql-override {prs | stu | st2 | tnc | st3e | st3 | smc | prc | ssu-a | ssu-b | sec | eec1 | eec2}
        ssm-bit sa-bit
            [no] shutdown
        ql-selection
        ref-order first second [third]
        ref1
            ql-override {prs | stu | st2 | tnc | st3e | st3 | smc | prc | ssu-a | ssu-b | sec | eec1 | eec2}
            source-port port-id adaptive
            no shutdown
        ref2
            ql-override {prs | stu | st2 | tnc | st3e | st3 | smc | prc | ssu-a | ssu-b | sec | eec1 | eec2}
            source-port port-id adaptive
            no shutdown

The following example shows the command usage:

Example:

config>system# sync-if-timing
config>system>sync-if-timing# begin
config>system>sync-if-timing# external
config>system>sync-if-timing>external# input-interface
config>system>sync-if-timing>external>input-interface# impedance 50-Ohm
config>system>sync-if-timing>external>input-interface# no shutdown
config>system>sync-if-timing>external>input-interface# ql-override prs
config>system>sync-if-timing>external>input-interface# exit
config>system>sync-if-timing>external# exit
config>system>sync-if-timing# commit
config>system>sync-if-timing# bits
config>system>sync-if-timing>bits# interface-type 2048khz-G703

config>system>sync-if-timing>bits# output
config>system>sync-if-timing>bits>output# line-length 220
config>system>sync-if-timing>bits>output# no shutdown
config>system>sync-if-timing>bits>output# exit

config>system>sync-if-timing# ref2
config>system>sync-if-timing>ref2# no shutdown
config>system>sync-if-timing>ref2# ql-override prs
config>system>sync-if-timing>ref2# exit
config>system>sync-if-timing# exit
