Caveats

BLSR Support for Mixed Node Networks

The ONS 15327 is supported for BLSR in combination with ONS 15454 nodes only if Release 3.3 is installed and running on all BLSR nodes. If you wish to provision a BLSR on a combination of ONS 15327 and ONS 15454 nodes, you should upgrade to Release 3.3 on all ONS 15454 and ONS 15327 nodes first.

UPSR Functionality

DDTS # CSCdx40081

If, in an OC-48 UPSR network, there is an STS-3C circuit, using STS 4-6, that terminates on OC-12 IR cards, and 28 VT circuits are bulk provisioned between two nodes on the ring, the STS-3C circuit can take at least one traffic hit during the VT circuit provisioning process. This only occurs if an OC-12 IR card has been reset after the STS-3C circuit was created.

Deleting one or more VT circuits in the same situation may also cause an STS3C traffic hit. It is not known when or if this issue will be resolved.

TL1

Note To be compatible with TL1 and DNS, all nodes must have valid names. Node names should contain alphanumeric characters or hyphens, but no special characters or spaces.

TL1 Gateway Network Elements

The ONS 15327 cannot act as a TL1 Gateway Network Element in Release 3.3.

Changes in TL1

In Release 3.3, TL1 output has changed to conform to Telcordia standards as follows:

The time period parameter has changed from 15MIN to 15-MIN, and its position in the output has shifted.

The direction parameter, BTH, is no longer included in the output. Only TRMT, or RCV is valid.

The mondat and montm parameters have been added to the end of output.

For example:

In Releases 1.0.x, you would see:

>rtrv-pm-oc12::fac-2-1:1::,,,,15min; IP 1
