Baseband 5216/5212 • Baseband 5216/5212 hardware hardware is equipped with 3 Ethernet ports for transport • TN A: 1Gbps Electrical Ethernet (RJ45) • TN B and TN C: 1Gbps/10Gbps Electrical/Optical Ethernet (SFP+) (on 5212 TN C is 1G) simultaneously, either for resiliency • All ports may be used simultaneously, or for connecting site equipment

• Connectivity of site equipment may be achieved using routing or bridging • Completely flexible IP address and VLAN configuration for all traffic types • RPS is replaced by Bidirectional Forwarding Detection (BFD) • Virtual Routing is supported as an enabler for traffic separation

Baseband T605 Transmission capabilities • Flexible synchronization support & RAN Grand Master for synchronization (macro and small cells) • Abis over IP support for legacy GSM • OAM interface security, element management and network management same as Baseband 5212/5216

› Baseband unit for advanced routing functionality & traffic aggregation › Dual power feed › 8 x E1/T1 ports (TDM) › 5 x 1/10G ports (SFP/SFP+) › 4 x 1G ports (SFP) › 4 x 1G RJ45 electrical ports › 15 Gbps IMIX forwardin forwarding g capacity

The Baseband 5216 product has two SFP+ cages supporting both SFP (1G) and SFP+ (10G) modules (TN_B and TN_C). The Baseband 5212 product has two SFP+ cages supporting both SFP and SFP+ modules. TN_B support SFP and SFP+, TN_C supports only SFP With this feature it is possible to add the capability of supporting SFP+ modules which then can provide a line speed of 10 Gbps Default is 1Gbps

Static Routing IP Transport Network

Static

Baseband

Description –

Static routing for IPv4 traffic is supported

Benefit –

Enables layer 3 connectivity to other parts in the network , e.g IP Loopback interface and supports interface resilience R1

Ethernet Switching

Bridge

IP Transport Network

Baseband

Description ›

L2 switching can be used to connect external equipment on the site or aggregate multiple IP traffic flows to the transport network without creating additional IP sub network

Benefit › ›

Easy way to get connectivity to IP hosts without changing the IP address plan or adding additional hardware Switching will save number of IP addresses that is required for connectivity

Bridged Virtual Interface • Bridged Virtual Interface (BVI) makes it possible to have IP host functionality on an L2 Bridge

• The IP host acts as an IP gateway to the routing function Bridge

• The IP host can also be used for remote connectivity

Baseband

to the Baseband unit, for example by O&M configuration configuration management, and as an IP host for other internal applications

• Supports IPv6

BVI

IP loopback Interface Switch-site

IP

Baseband

SE

Description › The IP Loopback interface is a logical IP interface not connected to any particular physical interface or internal HW in the Baseband › Supports IPv6

Benefit › The loopback interface can be used to test the connectivity beyond the physical interface › It can be used as an IP -endpoint to support interface resilience together with the static routing feature preferably together with BFD

Virtual Routers • Virtual Routers simplifies traffic separation and adds support for overlapping IP addresses • Possibility of overlapping IP addresses/routes • Default routes possible for both RAN and RAN O&M traffic

VR LTE/WCDMA

• Typical use case is: • Separate RAN traffic from O&M traffic
