Telephone Line Connections
The system requires two telephone cables, and related connection points:
• One telephone line for use when calling for service
• One analog telephone line to connect the RSN modem to a telephone connection

NOTE
A dedicated phone line provides the most reliable service
for RSN connections. RSN 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.
