Application Server; an M3UA term that describes software that processes M3UA messages. The SGA.
ASP
Application Server Process; defines the IP interfaces to which the SG sends M3UA traffic.
B
BTS Shared Point Code Configuration
A configuration in which a Cisco BTS 10200 Softswitch OPC and the SG with which it connects share the same SS7 point code (OPC) value. In this configuration, the SG connects directly to an STP via SS7 A-links, F-links, or E-links.
BTS Mated STP Pair Configuration
A configuration in which the Cisco BTS 10200 Softswitch and the SG with which it connects do not share the same SS7 point code (OPC) value. In this configuration, the SGs operate as STPs.
An M3UA term describing a signaling network topology in which two or more physical SGP nodes operate as a single SG node, thereby providing hardware redundancy.
DUNA
M3UA Destination Unavailable message.
DUPU
M3UA Destination User Part Unavailable message.
E
EMS
Element Management System.
F
FS
BTS Feature Server
FSAIN
BTS Feature Server for AIN services such as LNP and 800 services.
FSPTC
BTS Feature Server for POTS and Centrex services such as ACAR and CNAM.
G
GTT
Global Title Translation.
I
ITP
Cisco IP Transfer Point. This is the SGP that is used in combination with the Cisco BTS 10200 Softswitch to form the SIGTRAN signaling solution.
M
M3UA
MTP3 User Adaptation Layer.
MIM
M3UA Interface Module
MTP3
Message Transfer Part Level 3.
N
NMS
Network Management System.
NSO
Non-Stop Operation.
R
Routing Context
A value that uniquely identifies a routing key.
Routing Key
A set of SS7 parameters, such as DPC, OPC. SI, CIC-range, and SSN, that uniquely define the range of signaling traffic to be handled by a particular AS.
S
SCON
M3UA Signaling Congestion message.
SCCP
Signaling Connection Control Part.
SCTP
Stream Control Transmission Protocol. IETF standard for reliable transport over IP. Used instead of TCP/UDP/RUDP.
SEP
Signaling End Point.
SG Group
A Cisco BTS term that describes the pairing of SGs to form redundancy for the Cisco BTS 10200 Softswitch D-link solution. An equivalent ITP term that describes this pairing is SG Mated Pair.
SG Mated Pair
An ITP term that describes the pairing of SGs to form redundancy for the Cisco BTS 10200 Softswitch D-link solution. An equivalent Cisco BTS term that describes this pairing is SG Group.
Signaling Gateway
A logical gateway that interconnects IP signaling over SIGTRAN to SS7 network signaling over SS7 (T1/E1) links. It can be made up of one or more signaling gateway processes. The solution described in this document allows a maximum of two SGPs (ITPs) to be combined to form a single SG.
Signaling Gateway Process
A physical gateway that interconnects IP signaling over SIGTRAN to SS7 network signaling over SS7 (T1/E1) links. One or more SGPs can be combined to form a single SG. The solution described in this document allows a maximum of two SGPs (ITPs) to be combined to form a single SG.
SIGTRAN
A group of IETF standards that describe the SS7 signaling functionality of hardware nodes that interconnect IP based networks to SS7 networks.
SGA
Signaling Gateway Adapter. A process on the Cisco BTS 10200 Softswitch that processes ISUP related calls.
SGP
Signaling Gateway Process.
STP
Signaling Transfer Point.
SUA
SCCP User Adaptation Layer.
T
TCAP
Transaction Capability Application Part
TFA
MTP3 Transfer Allowed message.
TFC
MTP3 Transfer Control message. MTP3 message for congestion indications.
TFP
MTP3 Transfer Prohibit message.
TSA
TCAP Service Adapter. A process on the Cisco BTS 10200 Softswitch that processes TCAP related calls.
