Telephone Line Connections
The system requires up to two telephone cables, and related connection points:

One telephone line for use when calling for service

One analog telephone line to connect the ASN modem, if used, to a telephone
connection point
A 7-ft (2.13m) telephone cable is shipped with the modem assembly.

A dedicated phone line provides the most reliable service
for ASN connections. ASN calls routed through a PBX
might be slow due to the load on the PBX, or might not
complete successfully because the calls can become
disconnected. If you must use a PBX, do not route the
telephone extension through a switchboard; instead,
provide a direct-dial analog number.
If no modem is installed, a second telephone line is not necessary. A modem is not
necessary in the following situations:

If your system will connect to a network with Internet access, you may choose to
use the Internet to send alarms to the ASN and allow the CAC or your authorized
Stratus service representative to connect to your system over the Internet for
troubleshooting.

If you implement ftGateway groups, only one system in the group requires a
modem. See
“Site Planning for Systems in an ftGateway Group” for more
information.
N O T E
ftSSS for VMware vSphere does not support VTMs or
ftGateway groups.
