Connect Cables
Warning
Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Statement 1030
Warning
The ISDN connection is regarded as a source of voltage that should be inaccessible to user contact. Do not attempt
to tamper with or open any public telephone operator (PTO)-provided equipment or connection hardware. Any
hardwired connection (other than by a nonremovable, connect-one-time-only plug) must be made only by PTO staff
or suitably trained engineers. Statement 23
Warning
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage
(TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports
both use RJ-45 connectors. Use caution when connecting cables. Statement 1021
