The primary module is responsible for the management functions of the entire SPA8000, in addition to handling calls on Line 1 and Line 2. These management functions include remote provisioning, firmware upgrades, the administration web server, IVR functions, and SIP NOTIFY control messages (over Line 1 or 2). The IVR functions are accessed by connecting an analog telephone to Line 1 or Line 2. 2-16 Linksys ATA Administrator Guide Document Version 3.1

Connecting the SPA8000
The SPA8000 provides up to eight analog telephone connections, and is designed to function as a
network endpoint. This section describes the architecture and connectivy requirements of the SPA8000
and includes the following topics:
•
SPA8000 Architecture, page 2-16
•
Connectivity Requirements, page 2-17
SPA8000 Architecture
As shown in
Figure 1-14
, the SPA8000 consists of four hardware modules: one primary (Module 1) and
three secondary modules (Modules 2, 3, and 4).
Each module provides two FXS ports.
The primary
module supports Line 1 and Line 2, while the three secondary modules support Line 3-4, 5-6, and 7-8.
Figure 1-14
SPA8000 Internal Configuration
The four modules are interconnected through an internal IP network, configured automatically as a
single subnet, which by default is assigned the network address 192.168.0.0 with a subnet mask of
255.255.255.0. If a network conflict is detected from the device connected on the AUX port, the internal
network is automatically changed to 192.168.1.0.
The primary module is responsible for the management functions of the entire SPA8000, in addition to
handling calls on Line 1 and Line 2. These management functions include remote provisioning, firmware
upgrades, the administration web server, IVR functions, and SIP NOTIFY control messages (over Line
1 or 2). The IVR functions are accessed by connecting an analog telephone to Line 1 or Line 2.
