Setting the Interfaces
Setting SONET Transmit Interface
Setting SONET Transmit Interface
Description SONET transmit interface settings should match the network equipment settings of Rate, Wavelength and Mapping, determine the payload to be tested and set background conditions to prevent alarms while testing.
TIP:If you wish to set the HP 37718A transmitter and receiver to the same interface settings choose OTHER SETTINGS CONTROL 
COUPLED .
HOW TO: | 1 | Make your choice of SIGNAL rate. |
|
| If Option 106, Dual Wavelength optical module, is fitted and an optical |
|
| rate is chosen, choose the required wavelength (1550) or (1310). |
|
| If |
|
| Choose INTERNAL unless THRU MODE is required. If THRU MODE is |
|
| chosen, see "Setting SONET THRU Mode " page 11. |
| 2 | Make your choice of CLOCK synchronization source. The RECEIVE |
|
| clock synchronization choice depends on the SONET Receive Interface |
|
| choice. |
|
| EXTERNAL allows a choice of MTS, BITS or 10 MHz clocks. |
| 3 | If required choose the FREQUENCY OFFSET value. See “Adding |
|
| Frequency Offset to SONET Signal” page 31. |
