2. Click OK Button
* Per Hop Behaviours for Signaling Group1..6 are fixed.
A Per Hop Behavior (PHB) is the externally observable forwarding behaviour applied at a DS-compliant node. In WCDMA BTS, the difference between the PHBs is reflected by the queuing behaviour.
The Expedited Forwarding (EF) PHB is supported according to RFC 3246.The EF PHB is intended to be used for loss sensitive, low latency, low jitter, assured bandwidth, end-to-end service through DS domains. The typical traffic to use this PHB for would be voice, video and other services that require CS type of service quality.
The Assured Forwarding (AF) PHB is supported according to RFC 2597.The WDCMA BTS supports AF1, AF2, AF3 and AF4 PHBs with a single (low) drop precedence level per class.
The Best Effort (BE) PHB is supported according to RFC 2474.The Best Effort (BE) traffic class shall be the default way of handling non-delay, non-loss sensitive data packets in the IP-based Radio Access Network. Packets classified for BE PHB are basically served in the best possible way, but with no guarantee whatsoever. The reserved DiffServ Code Point (DSCP) for BE is zero (000000). This DSCP cannot be used for any other PHB. It is be possible, however, to map other DSCPs to the BE PHB additionally.
WCDMA BTS differentiates between six user traffic types that can be signalled from RNC, refered to as SignalingGroups. For each Signaling Group, an individual Per Hop Behaviour (and optional VLAN P-bit) is assigned.
Furthermore in IP Iub Transport Mode for the traffic types BFD, ICMP, ToP, DCN (TCP) and NBAP (SCTP) PHB, DSCP and VALN p-bit can be set.
Each PHB is associated to a certain Differentiated Services Code Point. This association is user-configurable. However, the default mapping is as follows:

VPI numbering scheme for Iub (1/2)
In most cases, BS traffic is separated over two VPs that are terminating in the BS. One for O&M traffic, and one for signalling and user traffic. Or all in one single VP (Signalling, User data and O&M).
The most widely used VPIs are VPI=0 for O&M, and VPI=1 for signalling and user traffic.
As seen in slides above, All 3 different basic solutions can be used to connect BS to RNC, that’s why the number of initial VPs connected to the RNC varies from one topology to another.
When using solution 2 (VP level cross-connection) or solution 3 (VC level cross-connection), the planner may need to create a lot of VPs on the same ATM interface, those VPs should respect the restrictions imposed by, ITU-T, ATM Forum and the hardware limitations, but on the other hand planners must take advantage of VPI/VCI numbers re-use
FTM Iub Parameter planning
41 © Nokia Siemens NetworksCustomer Confidential
VPI numbering scheme for Iub (2/2)
If the VP level cross-connection solution is used, it is always preferable to terminate in the BS VPIs 0 and 1.
Of course, other VPIs than 0 and 1 can be terminated in the BS as long as the restriction rules are respected.

Traffic Descriptor Identifier:Identifies the traffic descriptor in the FTM. Value can be an integer > 100.
Conformance Definition: Specifies the type of conformance test performed on the trafficstream by Usage Parameter Control (UPC). The FTM enforces the correspondence between conformance definition and service category. For CBR the conformance definition is CBR.1 and for UBR either UBR.1 or UBR.2.
Peak Cell Rate: Specifies the peak cell rate (PCR) assigned or reserved in both egress and ingress directions of transmission across the VP or VC link that is terminated.
The rate is given in cells per seconds. It cannot be greater than the line rate of the source.
The exact allowed value range depends on the type of interface (E1, T1, SDH, IMA, ATMOverEthernet)
Minimum Desired Cell Rate: Minimum Desired Cell Rate (MDCR). Is the targeted minimum throughput of a UBR connection in cells per second. The parameter can be set optionally for UBR connections. The same value applies both for ingress and egress traffic.
Note: The value of the MDCR cannot exceed the PCR.
UBRshare : UBRshare allows to weight the traffic exceeding the Minim Desired Cell Rate among UBR connections that share the same ATM interface. An individual UBR connection may get at least the ingress MDCR and up to ingress MDCR + ingressUBRshare_i / Sum(ingress UBRshare_i) * ingress EBW. Where ingres EBW is the currently available ingress bandwidth for the traffic of all the UBR connections sharing the same ATM interface.
The value of UBR Share applies to both ingress and egress traffic.

Vlan Enabled flag: This flag indicates if Vlan mapping is enabled for this ethernet interface. Value 'true' means that Vlanmapping is enabled. In case Vlan mapping is not enabled, all messages on the interface will be sent in plain format.
Vlan ID: Vlan ID to be used over this ethernet interface. The parameter is only relevant if vlan mapping is enabled (parameter vlanEnabled has value true).
VLAN ID : Between 0 and 4094

Synchronization - Settings in AXC
• You can define one primary (active) synchronisation timing source and one secondary (stand-by) timing source.
• If the primary timing source fails, Nokia AXC will automatically switch to the secondary source and a warning will be generated.
• If no secondary source is configured or the secondary source fails as well, an alarm is raised.
• When the primary source becomes available again, Nokia AXC switches back to it. • If both of these synchronisation sources should fail, Nokia AXC will switch to hold-
over mode for up to 24 hours, and after 24 hours to the internal clock (free-run mode).
• The hold-over mode is not displayed in Nokia AXC Manager. • A maximum of 3 timing sources are possible, the third always being the internal
clock.
Maintaining the AXC (DN 02166657) Chapter 4.3.8
• NND provides ATM level topology information to the NetAct ATM Manager
• NND can send information packets through each AXC interface.
• By default NND is enabled
