CPU Module

The CPU (Central Processing Unit) module, shown in the figure below, is located to the
right of the six I/O analog/digital module slots.
Refer to the figure in 'Mediant 1000 Front Panel' on page
module's front panel ports and connectors, which are described in sequence from left to
right in the following subsections.
2.1.2.1

Dry Contact Connector (Labeled I and II)

The Mediant 1000 provides dry contacts that can be connected to an external audible or
visual alarm system (bell, siren, hooter, or light).
2.1.2.2

Audio IN/OUT1

The Audio IN/OUT port is indicated by the musical note and loudspeaker symbols (refer to
the figure in 'Mediant 1000 Front Panel' on page 21). It is used for Music on Hold (IN) and
paging (OUT).
2.1.2.3

10/100 Base-TX Ethernet Ports (Labeled I and II)

Two 10/100 Base-TX Ethernet ports provide a dual Ethernet redundancy scheme,
protecting against failure (for example, a disconnection) of any cable or associated LAN
switch port.
SIP User's Manual
The standard FXO modules support outdoor and indoor (lightning protection)
loop start signaling. For ground start signaling, the FXO G modules are
required. These modules support loop and ground start, and only support
indoor protection. (The FXS modules support both loop and ground start
signaling.)
To enable ground start, use the ini file parameter GroundKeyDetection (refer
to 'System Parameters' on page 308).
