1.0 Introduction
The C900TTL-E Dialer Capture Module (C900TTL-E)
is designed to link a control panel's digital dialer (data
output) to an Ethernet connection on a local area
network (LAN) or wide area network (WAN).
When the dialer has data to report, the C900TTL-E
provides the signals and voltages necessary to simulate
a public switched telephone network (PSTN)
connection to the central station. The C900TTL-E then
decodes the digital dialer message and delivers the
decoded signals through the Ethernet connection to the
Conettix D6600 Communications Receiver/Gateway
(D6600). When the D6600 acknowledges receipt of the
message, the C900TTL-E sends an appropriate
acknowledge message to the dialer. This protocol
maintains true end-to-end security.
The C900TTL-E has three modular jacks:
•
TELCO for connection to the public switched
telephone network (PSTN)
•
PANEL for connection to a digital dialer using a
telephone cord
•
ETHERNET for connection to the network.
In Intercept Mode, the C900TTL-E connects the digital
dialer to a LAN or WAN. In Fallback Mode, the
C900TTL-E connects the PSTN to the dialer, shunting
itself out of the phone circuit. Intercept Mode is
maintained only if the C900TTL-E CPU is functioning
(Output 1 held low). This ensures the Fallback Mode if
an operational failure occurs.

Failure to follow these instructions might
result in failure of the system to transmit an
alarm condition. Bosch Security Systems,
Inc. is not responsible for improperly
installed, tested, or maintained devices.
Inform the central station and the local
authority before installing the C900TTL-E in
an existing system.
Disconnect all power to the control panel
before installing the C900TTL-E.
