* Permitted fiber optic cable length differs according to fiber characteristics,
splices, and connectors.
 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.
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-11 TDMoIP traffic for delay-sensitive and secure
applications. IPmux-11 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.
