*Permitted fiber optic cable length differs according to fiber characteristics, splices, and connectors.

Note

 

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.
