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 a modem dedicated to ASN connectivity, if
used, to a telephone connection point
A 7 ft (2.13m) telephone cable (minimum 26 AWG phone cord) is shipped with the
modem, except with orders destined for the Republic of Korea.
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.
Always use telephone cable that is 26 AWG or greater and is UL approved.
