This section provides the specifications of the HWECC solution.
Table 1 lists the specifications of the HWECC solution supported by the OptiX RTN 980. Please read the product book to get more specifications.
| Item | Specifications | |
|---|---|---|
| DCC type | SDH line or SDH radio |
|
| PDH radio (capacity: equal to or greater than 16xE1) | 3 bytes (D1 to D3) | |
| PDH radio (capacity: less than 16xE1) | 1 byte (D1) | |
| Integrated IP radio | 3 bytes (D1 to D3) | |
| Channelized STM-1 port |
|
|
| External clock port | Some timeslots (serving as DCC bytes) in received E1s. | |
| Inband DCN channel type | Integrated IP radio | Partial Ethernet service bandwidth in a microwave frame. |
| FE/GE port | Partial Ethernet service bandwidth. | |
| Maximum number of inband DCN channels | 128 |
|
| Extended channel type | NMS port or NE cascade port (all the port bandwidth). | |
| Range of VLAN IDs used by the inband DCN | 2 to 4094 (4094, by default). The inband DCN VLAN can be set by NE or port. |
|
| Range of bandwidth provided by the inband DCN | 64 kbit/s to 5000 kbit/s. |
|
| Setting of inband DCN packet priorities | Supports the setting of VLAN priorities and DSCP values for DCN packets. | |
| Extended ECC | Extension mode |
|
| Number of NEs (including a server and its clients) |
NOTE:
In specified mode, a server can be connected to a maximum of seven clients. If more than seven clients are required, use multilevel extended ECCs. |
|
| NMS access mode | Gateway-based access mode, which means that the NMS can access a non-GNE only through its GNE. | |
| Access control | Supported. | |
| Scale of a DCN subnet | A DCN subnet with a bandwidth of 192 kbit/s should have 120 NEs or less (when the network depth is not more than 15 NEs). | |
