Alcatel-Lucent MDR-8000 - Typical Interconnect Scenarios

3-60
3.19.2 Typical Interconnect Scenarios
Refer to CD, Connecting MDR-8000 Radio TMN Interface in an Ether-
net LAN, for limitations on interconnecting radios and equipment at a
site.
3.19.2.1 Scenario 1 – Daisy Chain, Bridged Connection
See Figure 3 - 35. In this scenario, four TMN interface modules are connected to the LAN.
Daisy chaining prevents having to use external equipment to connect to the LAN. Daisy
chaining is typically used instead of a costly battery powered switch/hub at smaller junc
-
tion stations and/or battery powered remote sites where ac power is not available.
This is accomplished using the Uplink (U) ports on the TMN interface modules on shelves 2
and 3 to connect to the TMN interface module in shelf 1. The uplink port on the TMN inter
-
face module in shelf 3 connects to the Ethernet 2 port TMN interface module in shelf 2.
3.19.2.2 Scenario 2 – Switched Connection
See Figure 3 - 36. In this scenario, four TMN interface modules are connected to the LAN
via a switch/hub using the Ethernet uplink port on each module. Ethernet 2 or 3 could be
used with a crossover cable.
Since many switch/hubs are powered by ac, this scheme is typically
used at terminals where ac power is accessible.
3.19.2.3 Scenario 3 – Front PPP Port Connections
For TMN to TMN PPP connections from Normal (DCE) to Crossover (DTE) or vice-versa, use
standard Cat. 5 cable. For other PPP connection options see
Figure 3 - 37 and Figure 3 - 38.
