SSN2SLO112 Overview
SLO1 Feature Code
The number code that follows the board name in the bar code is the feature code of the board. The feature code of the SLO1 indicates the type of optical interface.
| Board | Feature Code | Type of Optical interface |
|---|---|---|
| SSN2SLO110 and SSN3SLO110 | 10 | S-1.1 |
| SSN2SLO111 and SSN3SLO111 | 11 | L-1.1 |
| SSN2SLO112 and SSN3SLO112 | 12 | L-1.2 |
| SSN2SLO113 and SSN3SLO113 | 13 | Ve-1.2 |
| SSN2SLO114 and SSN3SLO114 | 14 | I-1 |
| SSN2SLO115 | 15 | S-1.1 |
| SSN2SLO116 | 16 | L-1.1 |
| SSN2SLO117 | 17 | L-1.2 |
| Port type | Description |
|---|---|
| I-1 | 2 km STM-1 two-fiber bidirectional optical interfaces |
| S-1.1 | 15 km STM-1 two-fiber bidirectional optical interfaces |
| L-1.1 | 40 km STM-1 two-fiber bidirectional optical interfaces |
| L-1.2 | 80 km STM-1 two-fiber bidirectional optical interfaces |
| Ve-1.2 | 100 km STM-1 two-fiber bidirectional optical interfaces |
SSN2SLO112 Version Description
The SLO1 is available in two functional versions, namely, N2 and N3. The difference between the two versions is with regard to whether they support the TCM function and AU-3 services. The N3SLO1 is discontinued.
| Item | Description |
|---|---|
| Functional versions | The SLO1 is available in two functional versions, namely, N2 and N3. |
| Differences |
|
| Substitution | When the N2SLO1 is not configured with the TCM function and AU-3 services, the N3SLO1 can substitute for the N2SLO1. |
NOTE:
When you configure the MSP or SNCP, you cannot configure the N3SLO1 as the protection board if the working board is the N2SLO1 on which the TCM function is enabled or AU-3 services are configured. Otherwise, the services are interrupted when a switching operation is performed.
Version Mapping
| Board | Start Version |
