HOW TO: | 1 Choose the required SIGNAL rate. |
| Rates of DS1, DS3, 2 Mb/s and 34 Mb/s are available. |
| 2 If you have chosen 2 Mb/s as the SIGNAL rate, choose the required |
| CLOCK SYNC source - internally generated or recovered from the |
| received DSn signal. |
| If Jitter, Option 204, 205 or 206, is fitted and SIGNAL 2 Mb/s is chosen |
| a 2M REF choice is added to the menu. This allows you to choose the |
| synchronization source for the 2 Mb/s reference. The synchronization |
| source is supplied from the SONET Clock module. It can be internally |
| generated, derived from an external clock or recovered from the |
| SONET received signal. |
