rate-step — Specify the subrate value for the associated DS-3.
Values
threshold
Syntax threshold {ber-sd | ber-sf} rate {1 | 5 | 10 | 50 | 100}
no threshold {ber-sd | ber-sf}
Context config>port>tdm>ds1
config>port>tdm>e1
Description This command configures the line signal degradation bit error rate (BER) and line signal failure thresholds.
Line signal (b2) bit interleaved parity error rates are measured and when they cross either the degradation or
failure thresholds alarms are raised (see the report-alarm line & section command), furthermore if the failure
threshold is crossed the link will be set to operationally down.
The no form of this command reverts to the default value.
Default threshold ber-sd rate 5
threshold ber-sf rate 50
Parameters ber-sd — Specifies the BER that specifies signal degradation.
ber-sf — Specifies the BER that specifies signal failure.
rate — Specifies the number of errors, in millions.
timeslots
Syntax timeslots timeslots
no timeslots
Context config>port>tdm>ds1>channel-group
config>port>tdm>e1>channel-group
Description This command defines the list of DS-0 timeslots to be used in the DS-1 or E-1 channel-group. The timeslots
are defaulted as defined below when encap-type is set to/from atm. ATM channel groups do not allow
timeslots to change.
The no form of this command removes DS-0 timeslots from a channel group.
Default no timeslots — Non-ATM channel groups.1-24 — Channel groups configured under DS-1 with encap set to
ATM.
2-16,18-32 — Channel groups configured under E-1 with encap set to ATM.
Description
timeslots — Specifies the timeslot(s) to be associated with the channel group. The value can consist of a list
