When used for M3UA backhaul operation, the Signaling Gateway may operate with an ASP operating either an Dialogic M3UA Application Server or an Application Server provided by a third party vendor. See the Dialogic® SS7 Protocols Programmer’s Manual for SIGTRAN Host Software for documentation on the configuration and use of a Dialogic M3UA Application Server.
1.3Applicability
This manual is applicable to SS7G2x units with software V3.02 and later installed. This manual is not applicable when operating as a Signaling Interface Unit (SIU) or as a DSC Protocol Converter (DSC). See the Dialogic® SS7G2x SIU Mode User Manual and the Dialogic® SS7G2x DSC Mode User Manual for descriptions use of these modes of operation.
1.4Hardware Overview
The Signaling Gateway may be purchased as one of two equipment types; SS7G21 and SS7G22. Each equipment type uses the same chassis and operates with the same software, but differ in the type of pre- installed SS7 Signaling boards. This provides options in the numbers and types of links and ports available.
An SS7G21 may be purchased with one, two, or three SPCI2S boards (where each board provides four SS7 links, two T1/E1 interfaces and two V.11 serial ports per board) or one, two or three SPCI4 boards (where each board provides four SS7 links and four T1/E1 interfaces per board).
An SS7G22 may be purchased with one, two or three SS7HDP boards (where each board provides 64 SS7 links and four T1/E1 interfaces per board) with a system maximum of 128 SS7 links.
When T1 or E1 is selected, the Signaling Gateway may be configured to pass the bearer channels from one PCM port to another, effectively “dropping out” the signaling in line.
See Chapter 2, “Specification” for a full definition of the capabilities of the system.
1.4.1Part Numbers
See the Dialogic® SS7G21 and SS7G22 Hardware Manual for a full list of the ordering codes and definitions of all of the hardware variants of the two equipment types.
1.5Connectivity
TDM SS7 signaling can interface to the Signaling Gateway using balanced 1544 kbit/sec (T1) balanced connections in accordance with G.733 or 2048 kbit/sec (E1) connections in accordance with G.703. SS7 signaling can also be presented on a V.11 (56/64 kbit/sec) synchronous serial interface.
MP2A signaling used for communication between paired Signaling Gateways can be received at the conveter using 4 x 1 Gbit/sec RJ45 Ethernet™ interfaces.
1.6User Interface
The Signaling Gateway provides serial port and telnet connections for configuration and management. All ports provide identical functionality and operate using
The serial and telnet ports allow the user to configure the Signaling Gateway for operation and to carry out subsequent modifications to the configuration. They allow the user to read the current status of the various signaling entities and to view the current active alarms and a history of past alarm events.
