*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 Sensitivity–Optical 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.
QoS
QoS supports:
• Labeling IP level priority (ToS/Diffserv) for TDMoIP® packets
• VLAN tagging and priority labeling according to IEEE 802.1p&Q for TDMoIP®
packets.
The user can configure the ToS (Type of Service) of the outgoing TDMoIP®
packets. This allows an en-route Layer 3 router or switch, which supports ToS, to
give higher priority to IPmux-1/1E TDMoIP® traffic for delay-sensitive and secure
applications. IPmux-1 allows you to configure the WHOLE ToS byte field, since
different vendors may use different bits to tag packets for traffic prioritization.
This also enables operation according to various RFC definitions (for example RFC
2474, RFC 791). The user can also configure VLAN priority bits for Level 2 priority.
