Adding ATM Traffic ResourcesATM service types

Service typeDescription

Full name Abbreviation

Constant Bit Rate

CBR No error check, flow control, and other processing

Real Time Variable Bit Rate

RT-VBRUsed to describe the service with variable data rates and strict real time requirement, for example, interactive compressed video such as videoconference

Non-Real Time Variable Bit Rate

NRT-VBRUsed in timing transmission as E-mail transmission. In such a case, some delays and variations can be accepted by the application

Unspecified Bit Rate

UBR

No commitment or feedback to congestion. It is suitable for sending IP data. In case of congestion, UBR cells will be discarded. However, neither relevant feedback nor the request for slowing down the transmission speed will be returned to the senderThe BSC6800 also supports UBR+, which ensures the minimum cell rate

Basic Information —RNC backup configuration （ optional）ADD URNCPOOL\ADD URNCPOOLMEMBER


Use this command to add a RNC pool. Two RNCs with Iur interface can be configured as a RNC pool. The two RNCs supply redundancy backup for each other. For a NodeB, the local RNC acts as the primary RNC and the peer RNC as the secondary RNC. If the primary RNC is faulty, the secondary RNC takes over the traffic carried by the NodeB.

Parameters of ADD TMMMAP command


By default, 14 transport resource mappings (the index ranges from 0 to 13) are added. In addition, the 14 transport resource mappings cannot be modified and deleted.





partners : Arial


18pt Color:Black



partners : Arial

Parameters of ADD TRMFACTOR command


By default, the activation factor table with index 0 is configured in the RNC. In addition, this index cannot be modified and removed. The RNC uses the activation factor to calculate the admission bandwidth. The admission bandwidth is calculated by using the following formula: Admission bandwidth = Bandwidth at the transport layer * Activation factor/100.

Parameters of ADD LOADEQ command for IUCS/IUPS/IUR


If the NodeB supports ATM/IP dual stack or hybrid IP, you can configure the path load EQ threshold table.

The path load EQ threshold table with index 0 is the default table in the RNC, and it cannot be modified or deleted.

Parameters of ADD ADJMAP command for IUCS/IUPS/IUR


This command is used to configure the TRM mapping table and activity factor table for users of different priorities.

When Interface Type is IUB, Resource Management Mode can be SHARE or EXCLUSIVE.

When Interface Type is IU-CS,IU-PS,IUR, Resource Management Mode can only be SHARE.

ADD IPOAPVC: add an IPoA PVC between the RNC and the NodeB.

ADD UNODEBIP: add the remote IP address of the NodeB to RNC. Then RNC will configure one 80 subnet O&M route to NodeB.

Adding an OM Channel on the Iub Interface Parameters of ADD DEVIP command

Each interface board can be configured with a maximum of 16 device IP addresses.

For the AEUa, AOUa, UOIa(ATM), AOUc, and UOIc boards, a device IP address is an address of the IPoA Client.

Boards in IP transmission mode can be configured with the DEVIP only in the type of "LOGIC_IP". Boards in ATM transmission mode can be configured with the DEVIP only in the type of "IPOA Client IP Address".
