platforms provide an SCbus interface for interconnection of multiple DM3 platforms, or connection to other SCSA- compatible hardware. The DM3 platform supports timeslot bundling for high bandwidth, and can access up to 256 of the 2048 SCbus timeslots via two SC4000 ASICs.
SIP: Session Initiation Protocol: an Internet standard specified by the Internet Engineering Task Force (IETF) in RFC 2543. SIP is used to initiate, manage, and terminate interactive sessions between one or more users on the Internet.

Transmission Control Protocol: The TCP/IP standard transport level protocol that provides the reliable, full duplex, stream service on which many application protocols depend. TCP allows a process on one machine to send a stream of data to a process on another. It is
UDP: see User Datagram Protocol
UDPTL: Facsimile UDP Transport Layer protocol
User Datagram Protocol: The TCP/IP standard protocol that allows an application program on one machine to send a datagram to an application program on another machine. Conceptually, the important difference between UDP datagrams and IP datagrams is that UDP includes a protocol port number, allowing the sender to distinguish among multiple destinations on the remote machine.
