Setting the Interfaces
Selecting the Physical Transmit Interface for ATM Payloads
Selecting the Physical Transmit Interface for
ATM Payloads
Description ATM transmit physical layer settings should match the network
equipment settings in the same way as the SDH and PDH transmit
interfaces. The Interface selections available are determined by the
PDH/DSn and SDH modules fitted to your instrument.
Your selections are automatically transferred to the other TRANSMIT
displays. Selection of STM-4 OPTICAL signal at the ATM PHYSICAL
LAYER will cause the transmitter output SDH to change to STM-4
OPTICAL.
TIP: If you wish to set the HP 37717C transmitter and receiver to the same
interface settings choose .
HOW TO: 1 Make your choice of SIGNAL rate.
If an optical rate is chosen, choose the required wavelength.
Choose INTERNAL unless THRU MODE is required. Jitter may be
introduced into an STM-1, 140Mb/s, 32Mb/s or 2Mb/s signal with ATM
payload if THRU MODE is chosen.
2 Make your choice of CLOCK synchronization source. At SDH rates,
the RECEIVE clock sync choice is dependent upon the SDH Receive
