5.7.2.3 Structured/Unstructured E1
MINI-LINK TN R4 can use up to two of its connected E1s for transport of IP
DCN. The following options are available:
• Dedicated E1 for DCN
A structured or unstructured E1 can be dedicated for DCN. For the
structured E1, nx64 kbit/s timeslots can be configured for DCN transport.
The remaining timeslots are unused, that is cannot be used to transport
traffic. For the unstructured E1, the entire 2 Mbit/s is used for DCN
transport.
• E1 with traffic pass-through
In a structured E1 used for traffic, nx64 kbit/s timeslots can be used for
DCN transport. The DCN is inserted into the nx64 kbit/s timeslots internally
in the NE. The timeslots used for traffic is cross-connected in normal
manner through the NE.
5.7.2.4 nx64 kbit/s
nx64 kbit/s timeslots can be used for IP DCN as described in Section 5.7.2.3
on page 117.
5.7.2.5 2xE0
A PPP/E0 connection can be established to an external device from the SMU2.
5.7.2.6 DCC Radio Terminal
Each Radio Terminal provides a DCC of nx64 Kbits, where 2≤n≤9 depending
on traffic capacity and modulation, transported in the radio frame overhead.
5.7.2.7 10/100BASE-T
Each NE has a 10/100BASE-T Ethernet interface for connection to a site LAN.
This interface offers a high speed DCN connection.
The interface is also used at sites holding MINI-LINK HC and MINI-LINK E
with SAU IP(EX).
5.7.2.8 USB
The USB interface is used for a MINI-LINK Craft connection using a local IP
address.
