Stack Dynamics SS7 Stack - Specification MTP - 2 MTP-2 (Message Transfer Part Level 2) is responsible for reliable transfer of messages over a single signalling link between adjacent nodes. It ensures that messages are delivered over the link without corruption, in the correct sequence, without loss and without duplication. MTP-2 normally executes in the network interface card, while the rest of the stack executes in a host processor. Stack Dynamics MTP-2 is a card-level product, which SS7-enables the card. The card can then be used with a third-party SS7 stack as part of an SS7 solution. Stack Dynamics MTP-2 solves the card/SS7 integration problem. Stack Dynamics will integrate Stack Dynamics MTP-2 with any suitable network interface card and third-party SS7 stack. A "suitable" network interface card is one which: Provides one or more network interfaces. Usually these will be T1 or E1 interfaces. A T1 interface supports 24 timeslots of 64 kbit/s each. An E1 interface supports 32 timeslots of 64 kbit/s each. One or more timeslots may be used for SS7 links. Has a bus interface that is compatible with the host processor. Examples are PCI, Compact PCI, VME, S-Bus. Has a programmable on-card processor that is sufficiently powerful to handle the real-time requirements of MTP-2 processing. If multiple SS7 links are to be supported on the card then proportionately more power is required. MTP-1 is the physical (hardware) mechanism used by MTP-2 to transport messages across a link between nodes. Stack Dynamics MTP-2 makes relatively few assumptions about MTP-1. Typically MTP-1 will be a 64 kbit/s timeslot in an E1 or T1 digital path, but this need not be the case. Stack Dynamics will integrate Stack Dynamics MTP-2 with any of the standard host operating systems, such as: Solaris, HP/UX, AIX, Windows NT, LINUX. Stack Dynamics MTP-2 is an implementation of the ITU Q.703 recommendation. However Stack Dynamics MTP-2 will also support other standards, such as ANSI, Bell, BT, etc. as required.
