Ericsson MINI-LINK TN R4 ETSI - Ethernet Traffic

Basic Node
3.7 Ethernet Traffic
3.7.1 Overview
• ETU2 provides five 10/100BASE-T interfaces and one 10/100/1000BASE-T
interface. See Section 3.7.4 on page 38.
• ETU3 provides two 10/100/1000BASE-T interfaces and two
1000BASE-TX/LX/ZX, Small Form Factor Pluggables (SFP) interfaces, that
can be either electrical or optical. See Section 3.7.4 on page 38.
• NPU3 provides two 10/100BASE-T interfaces, one for Ethernet Traffic and
one for Ethernet Site LAN. See Section 3.3.1 on page 18
• NPU3 B provides two 10/100/1000BASE-T interfaces, one for Ethernet
Traffic and one for Ethernet Traffic or 10/100BASE-T Ethernet Site LAN.
See Section 3.3.1 on page 18
3.7.1.1 Ethernet over PDH
The Ethernet traffic is transported between NEs in multiple E1s, over a single
hop or through a network. Figure 31 on page 35 shows an example of how the
different units can be used in a network.

Figure 31 Ethernet traffic in a MINI-LINK TN R4 network
The bandwidth of each Ethernet bridge connection is nxE1 per inverse
multiplexer in the unit, where n≤48 for ETU2 and ETU3 (with a maximum of 96
E1s in total), and n≤16 for NPU3. NPU3 have one inverse multiplexer while
ETU2 and ETU3 has six.
Ethernet traffic is connected to the units using RJ-45 connectors with support
for shielded cable.
