4Motion 15 System Manual
The six single-Euro slots are intended for one or two redundant Power Interface
Units (PIUs) and up to four redundant Power Supply Units (PSUs). One of the
double Euro slots (Slot 5) is dedicated to the NPU module, with interfaces for
network backhaul, in-band and out-of-band (OOB) management connections.
Another double-Euro slot (Slot 6) is reserved for an optional redundant NPU (the
shelf is HW-ready for NPU redundancy). The remaining seven double-Euro slots
(1-4, 7-9) are dedicated for Access Unit (AU) modules, thereby enabling various
network topologies with up to 6 simultaneously operational AUs, and future
redundancy configurations. In addition, the shelf contains an Air Ventilation Unit
(AVU).
1.3.1.2 NPU
The Network Processing Unit is the controller of the Base Transceiver Station.
Serving as the central processing unit that manages the BTS components, the
NPU aggregates traffic to/from the AU modules, and transfers it to/from the IP
backbone through a dedicated Gigabit/Fast Ethernet interface. In addition, the
NPU can be operated in ASN-GW mode, in which case it also implements ASN-GW
functionality.
When operating in ASN-GW mode, the NPU implements the R3 reference point
toward the CSN, R4 reference point toward other ASN-GWs, and R6 reference
point toward AU/BSs. The R8 reference point traffic is transparently relayed
between AU/BSs (intra- or inter-BTS).
When operating in transparent mode, the NPU transparently relays R6 and R8
reference-point traffic between AU/BSs (intra- or inter-BTS).
The BreezeMAX shelf is hardware-ready for 1+1 NPU card redundancy.
The NPU main functions, when operating in transparent mode, are:
Aggregate backbone Ethernet connectivity for user and control traffic
Aggregate backbone Ethernet connectivity for management traffic (in-band or
out-of-band)
Connection to a cascaded shelf (future feature)
AU 6U high access unit, 4-channel, 802.16e MAC-modem-baseband IF card
AVU 2U high air ventilation unit, 9+1 redundancy fans with alarm control
