| Basic function | LSC converts signal as follows: 100GE/OTU4<->1x OTU4 |
| Client-side service type | 100GE: Ethernet service at a rate of 103.125 Gbit/s. OTU4: OTN service at a rate of 111.81 Gbit/s |
| OTN function | - Provides the OTU4 interface on WDM-side.
- Supports the OTN frame format and overhead processing compliant
with ITU-T G.709.
- ODU4 layer:
- When the client-side service type is 100GE, the board supports the
PM function.
- When the client-side service type is OTU4, the board supports the
PM and TCM functions, PM and TCM non-intrusive monitoring
functions.
- OTU4 layer: supports the SM function.
|
| WDM specification | Supports ITU-T G.694.1-compliant DWDM specifications. |
| Tunable wavelength function | The board can tune the optical signal output on the WDM side within
the range of 80 wavelengths in C-band with the channel spacing of
50 GHz. |
| ESC function | Supported NOTE:When being provisioned with the OTU4 service on the client side,
the TN12LSC board supports ESC transparent transmission, but not
ESC processing. |
| PRBS test function | When the client-side service type is OTU4, the PRBS function is
supported on the client side. When the client-side service type is 100GE or OTU4, the PRBS
function is also supported on the WDM side. |
| LPT function | Not supported |
| FEC coding | On the client side: Supports ITU-T G.709-compliant forward error
correction (FEC) on the client side, only when the client side
service type is OTU4. On the WDM side: The TN12LSC/TN13LSC board supports HFEC and SDFEC . The TN15LSC board supports HFEC and SDFEC2. The TN17LSC board supports SDFEC2. NOTE:Boards that use different FEC modes cannot interconnect with each
other. |
| Alarms and performance events monitoring | NOTE:Only the TN12LSC board does not support the monitoring of BIP8
bytes on the client side. |
| Regeneration board | The WDM-side signals from one TN12LSCT01/TN13LSCT01/TN15LSCT01
board can be regenerated by another
TN11LTXT01/TN54NS4T01/TN57NS4T01/TN12LTXT01/TN15LTXT01 board. The WDM-side signals from one TN12LSCT11/TN13LSCT11 board can be
regenerated by another
TN11LTXT11/TN54NS4T11/TN56NS4T11/TN12LTXT11/TN15LTXT11 board. The WDM-side signals from one TN15LSCT31 board can be regenerated
by another TN57NS4T31 board. The WDM-side signals from one TN15LSCT51/TN17LSCT51 board can be
regenerated by another TN57NS4T51/TN58NS4T51 board. The WDM-side signals from one TN15LSCT52/TN17LSCT52 board can be
regenerated by another TN57NS4T52/TN58NS4T52 board. The WDM-side signals from one TN15LSCT53/TN17LSCT53 board can be
regenerated by another TN57NS4T53/TN58NS4T53 board. The WDM-side signals from one TN15LSCT61/TN17LSCT61 board can be
regenerated by another TN57NS4T61/TN58NS4T61 board. |
| ALS function | Supports the ALS function on the client side when client services
are non-OTN services. |
| Test frame | Supported only when the client-side service type is 100GE. |
| Latency measurement | The TN13LSC/TN15LSC/TN17LSCboard supports latency measurement. The
bidirectional latency at the ODU4 layer between two OTU boards
supporting the latency measurement function can be measured, and
the latency data is displayed on the U2000. This function is not supported when the client-side service type is
OTU4. |
| IEEE 1588v2 | Not supported |
| Physical clock | When receiving 100GE/OTU4 services on the client side, the board
supports synchronous Ethernet transparent transmission instead of
synchronous Ethernet processing |
| Optical-layer ASON | Supported |
| Electrical-layer ASON | Not supported |
| Protection scheme | - Supports client 1+1 protection.
- Supports intra-board 1+1 protection (when working with the
OLP/DCP/QCP board).
NOTE:When the client-side service is OTU4, the TN12LSC board does not
support client-side 1+1 protection. |
| Loopback | Client side | Inloop | Supported |
| Outloop |
| WDM side | Inloop | Supported |
| Outloop |
