* 37717-60020/21 may be used (Structured PDH Modules). ** 37714-60012/
60013 may be used (STM1/4 Modules).
CAUTION If 37714-60012 (Option URU) is fitted, the optical output must be attenuated by 10
dB before connecting to the Optical input of any other 37717C optical module.
Failure to do this could result in damage to the HP 37717C. Table 3-1 lists a suitable
attenuator.
