*Permitted fiber optic cable length differs according to fiber characteristics, splices,
and connectors.
When a user port option (only UTP) is chosen, the network fiber option is LC. If
there is no user port, the network fiber option is SC.
To calculate Optical Budget:
Optical Budget [dB] =
Receive SensitivityOptical Power–3 (Aging) – Connectors/Patch Panels Loss
To calculate Distance:
Distance = Optical Budget/Maximum Loss
TDMoIP Operation Modes
E1/T1 operation modes are:
Unframed E1/T1 over UDP over IP over Ethernet
Fractional E1/T1 over UDP over IP over Ethernet
Fractional E1/T1 with CAS over UDP over IP over Ethernet.
ISDN BRI operation modes are:
NT mode over UDP over IP over Ethernet
TE mode over UDP over IP over Ethernet.
IPmux-1E with FXS/FXO/E&M operates in fractional E1/T1 with CAS over UDP
over IP over Ethernet.
