| Maintenance | |
| PRBS | Supported |
| Synchronization | |
| Physical layer clocks | Supports external clocks, line clocks, tributary clocks, and internal clocks. The port impedance is 120 ohms or 75 ohms (a converter can be used to provide a 75-ohm clock port). Supports non-SSM, standard SSM, and extended SSM protocols. Supports retiming of tributary clocks. Supports the locked, holdover, and free-run modes. |
