Signaling Transfer Points (STPs. 9.4.1 Definition - Signaling Transfer Points is a signaling network function that includes all of the capabilities provided by the signaling transfer point switches (STPs) and their associated signaling links which enable the exchange of SS7 messages among and between switching elements, database elements and signaling transfer point switches.
Signaling Transfer Points (STPs. 2.10.1 The STP element is a signaling network function that includes all of the capabilities provided by the STP switches which enable the exchange of SS7 messages between switching elements, database elements and signaling transfer point switches via associated signaling links. STP includes the associated link interfaces.
Signaling Transfer Points (STPs. 2.10.1 The STP element is a signaling network function that includes all of the capabilities provided by the STP switches which enable the exchange of SS7 messages between switching elements, database elements and signaling transfer point switches via associated signaling links. STP includes the associated link interfaces.
2.10.2 The STP routes signaling traffic generated by action of Carrier to the destination defined by the SBC-12STATE’s signaling network. Integrated services digital network user (ISUP) and Translational Capabilities Application Part (TCAP) signaling traffic addressed to SPs associated with Carrier set of links will be routed to Carrier.
2.10.3 SS7 Transport will apply to SS7 messages transported on behalf of Carrier from an SBC-12STATE designated STP pair to a to an SBC-12STATE STP pair located in a different LATA. In SBC- AMERITECH this arrangement will only be provided for STPs located in the same state. In SBC- 7STATE, the rate, per octet, will apply to octets comprising ISUP and TCAP messages. In SBC- AMERITECH the Signal Switching and Signal Transport rates will apply to ISUP and TCAP messages. In SBC-2STATE, SS7 transport is not available. However, transit signaling provides the ability for an interconnecting network (ICN) to pass signaling information through the SBC-2STATE network to a third party without requiring a trunking connection by a third party with SBC-2STATE.
Signaling Transfer Points (STPs. 3.1 Definition. Signaling Transfer Points (STPs) provide functionality that enable the exchange of SS7 messages among and between switching elements, database elements and signaling transfer points.
3.2 Technical Requirements - Signaling Transfer Points
3.2.1 STPs must provide access to all other Network Elements connected to the SBC MISSOURI SS7 network. These include:
3.2.1.1 SBC MISSOURI Local Switching or Tandem Switching;
3.2.1.2 SBC MISSOURI Service Control Points/DataBases;
3.2.1.3 Third-party local or Tandem Switching Systems; and
3.2.1.4 Third-party-provided STPs.
3.2.2 The connectivity provided by STPs must fully support the functions of all other Network Elements connected to SBC MISSOURI's SS7 network. This explicitly includes the use of SBC MISSOURI's SS7 network to convey messages which neither originate nor terminate at a signaling end point directly connected to the SBC MISSOURI SS7 network (i.e., transit messages). When the SBC MISSOURI SS7 network is used to convey transit messages, there must be no alteration of the Integrated Services Digital Network User Part (ISDNUP) or Transaction Capabilities Application Part (TCAP) user data that constitutes the content of the message.
3.2.3 If a SBC MISSOURI tandem Switch routes calling traffic, based on dialed or translated digits, on SS7 trunks between an MCIm local Switch and third party local Switch, SBC MISSOURI's SS7 network must convey the TCAP messages that are necessary to provide Call Management features (Automatic Callback, Automatic Recall, and Screening List Editing) between the MCIm local STPs and the STPs that provide connectivity with the third party local Switch, even if the third party local Switch is not directly connected to SBC MISSOURI's STPs.
3.2.4 STPs must provide all functions of the Message Transfer Port (“MTP”). This includes:
3.2.4.1 Signaling Data Link functions;
3.2.4.2 Signaling Link functions; and
3.2.4.3 Signaling Network Management functions.
3.2.5 STPs must provide all functions of the SCCP necessary for Class 0 (basic connectionless) service. In particular, this includes Global Title Translation (GTT) and SCCP Management procedures.
3.2.6 In cases where the destination signaling point is a SBC MISSOURI local or tandem switching system or database, or is an MCIm or third party local or tandem switching system directly connected to SBC MISSOURI's SS7 network, SBC MISSOURI STPs must perform final GTT of messages to the destination and SCCP Subsystem Management of ...
Signaling Transfer Points (STPs. BA will provide MCIm with unbundled access to its STPs enabling MCIm to activate its own signaling link transport in lieu of BA provided signaling link transport. In addition, STP connections will be provided to MCIm as requested to support interconnection at either or both MCIm’s STPs or switches to BA’s STPs.
