BLSR Attributes


Use the BLSR Attributes page in the BLSR Creation wizard to define the bidirectional line switched ring (BLSR) ring type, speed, name, and reversion properties. The following table describes the BLSR Attributes page fields and buttons.

Item

Description

Type

(ONS 15454 only) Sets the BLSR type, either two-fiber or four-fiber.

Note     ONS 15600 and ONS 15327 nodes support only two-fiber BLSRs.

Speed

Sets the BLSR ring speed. Valid entries are:

  • OC-12 for two-fiber BLSRs (ONS 15327 and ONS 15454)

  • OC-48 (ONS 15327, ONS 15454, and ONS 15600)

  • OC-192 (ONS 15454 or ONS 15600)

The speed must match the OC-N speed of the BLSR trunk cards installed on the nodes you want to include in the BLSR.

Ring Name

Sets the BLSR name. The name can have up to six alphanumeric characters, 0 to 9, A to Z (case insensitive). The ring name cannot be "all" because "all" is used in the TL1 RTRV-BLSR command to return all existing BLSRs.

Ring Reversion

Sets the amount of time that will pass before the traffic reverts to the original working path following a ring switch. The default is 5 minutes. Ring reversion can be set to Never.

Span Reversion

Sets the amount of time that will pass before the traffic reverts to the original working path following a span switch. The default is 5 minutes. Span reversion can be set to Never.

Next

Displays the Create BLSR page, where you define the spans to be included in the BLSR.

Cancel

Cancels BLSR creation and closes the Create BLSR wizard.

Help

Displays context-sensitive help for the Create BLSR wizard.
