Chapter 2: Specification
2.1 Hardware Specification
Full details of the Signaling Gateway hardware specification are given in the Dialogic
®
SS7G21 and SS7G22
Hardware Manual.
2.2 System Capacity
The maximum capacity is dependent on the number and type of signaling boards installed. The numbers
given in this section are for a single unit. Use of Signaling Gateways in dual pairs or in clusters proportionally
increases the capacity of the overall system while still acting as a single SS7 point code.
2.3 System Capabilities
• Maximum number of signaling boards: 3
• Number of 10/100/1000 Mbit/sec Ethernet interfaces: 4
2.4 Signaling Capabilities (Per System)
• Maximum number of SS7 Signaling Links (including M2PA): 128
• Maximum number of M2PA Signaling Links: 32
Note: A system supports up to 128 SS7 links, where each link can be used for either M2PA or MTP2.
The number of SS7 links used for M2PA reduces the number of links available for MTP2 and vice-
versa. For example, if 32 SS7 links are used for M2PA, 96 links are available for MTP2.
• Maximum number of SS7 link sets: 64
• Maximum number of SS7 routes: 128 per network
• Maximum number of Networks: 4
• Maximum number of Application Servers: 200
• Maximum number of Application Servers: 200
• Maximum number of M3UA routes: 200
• Maximum number of Network Contexts: 4
2.5 Physical Interfaces (Per Signaling Board)
• SPCI2S T1/E1 PCM interfaces: 2
• SPCI2S SS7 V.11 serial interfaces: 2
• SPCI4 T1/E1 PCM interfaces: 4
• SS7HDP T1/E1 PCM interfaces: 4
2.6 TDM Signaling Capabilities (Per Signaling Board)
• Maximum number of SS7 Signaling Links (SPCI4 / SPCI2S): 4
• Maximum number of SS7 Signaling Links (SS7HDP): 64
Note: The system limit for a Signaling Gateway is still 128 SS7 Signaling Links even when three
SS7HDP boards are installed.
