Why IP transport
IP is developing to allow the support of a mix of traffic types and to support low speed links.
The popularity of the Internet/World Wide Web and corporate LANs puts price pressure on IP networking equipment. the more economical IP network is preferred by a number of vendors.
Following the trend in network migration to protect your investment

SCTP layer in the protocol stack
Like TCP, SCTP is connection-oriented A connection-oriented protocol is one that requires a setup procedure to establish the
communication relationship (and state) between two parties In TCP, the communication relationship between two endpoints is called a
“connection” In SCTP, this is called an “association” this is because it is a broader concept than a
single connection (i.e. multi-homing) An SCTP association provides reliable data transfer of messages Messages are sent within a stream, which is identified by a stream identifier (SID) Messages can be ordered or un-ordered

SCTP layer in the protocol stack
Multi-stream support Streams are a powerful mechanism that allows multiple ordered flows of messages within a
single association. Messages are sent in their respective streams and if a message in one stream is lost, it will
not hold up delivery of a message in the other streams The application specifies the stream number to send a message on

IP Interface Board in NodeB
The DBS3800 of earlier versions has FE ports. Therefore, no hardware change is made.
To support the IP RAN feature, the BTS3812E and the BTS3812A require the NUTI board that can provide eight E1/T1 ports and two FE ports
