� It is not necessarily fully dedicated to the UTRAN
� Ipv4 backbone
� DiffServ Capable for the QoS Management

1.7 RNC Connection to the IP Backbone
� The RNC is connected to an IP backbone through a 7750 SR
� It is a layer 3 access router providing IP routing, DiffServ forwarding and L3 Carrier Grade.
� For redundancy purpose, this Service Router may be duplicated

1.8 NodeB Connection to the IP backbone
There are 3 ways to connect the NodeB to the IP backbone:
� An Ethernet Access Module (EAM) can be added in front of the Node B and an Ethernet Access Termination (EAT) in front of the RNC to access an Ethernet backbone only (using ATM pseudowires for ATM transport). In the Alcatel-Lucent global solution, EAM is a SAR7705 and EAT is a SR7750.
� the xDSL access can be used also for IP/Ethernet
� An Ethernet access can be used in addition to the existing connection to the ATM backbone

2.1 RNC Hardware
� New cards must be added to support the IP transport features
� The RNC must be equipped with 2 GigE 4 ports cards.
This card provide 4 GigaEthernet ports supporting the following interfaces:
� 1000BaseLX
� 1000BaseSX interfaces
� The 4pGe card has an operating capability of full data line rate (1 Gbit/s) for each port, however, the aggregated backplane interface throughput for the four ports is 2.5 Gbit/s.

2.2 RNC Hardware
� The 4ptGE cards routes IP packets from the RNC cards to the Network Elements (Node B and SGSN). They provide:
� Traffic management: QoS Mapping , Buffer Management, Queuing and Congestion Control, Scheduling, DiffServ Capable
� VLAN Support: to separate the traffic
� Defense Mechanisms with PDR (Protected Default Route) to spare the Layer 3 routing

2.3 RNC Hardware
� The 4pGigE cards must go in slots 14 & 15.
� If not present in the RNC, any PSFP / DCPS cards in slots 14 & 15 must be replaced by the two 4pGigE cards.

2.5 IP Backbone
� The UTRAN IP backbone and the CN IP backbone are supposed to be a level 3 or level 2 network with IPv4 addressing, IP (or IP/MPLS) routing and DiffServ forwarding.
� It is supposed to be secured and transparent : IP packets shall be conveyed without any modification of the UDP/IP headers because IP addresses and UDP ports are used as bearer identifiers.
