Asynchronous Terminal Connections
The route processor provides a console port to connect a terminal or computer for local console access.
The RP1 also provides an auxiliary port to connect to a modem for remote dial-in console access.
Both ports have RJ-45 connectors, support RS-232 asynchronous data, and have distance
recommendations specified in the IEEE RS-232 standard.
Interference Considerations
When wires are run for any significant distance, there is a risk that stray signals will be induced on the
wires as interference. If interference signals are strong, they can cause data errors or damage to the
equipment.
The following sections describe sources of interference and how to minimize its effects on the
Cisco
1000 Series Router system.
Electromagnetic Interference
All equipment powered by AC current can propagate electrical energy that can cause electromagnetic
interference (EMI) and possibly affect the operation of other equipment. The typical sources of EMI are
equipment power cords and power service cables from electric utility companies.
Strong EMI can destroy the signal drivers and receivers in the Cisco 1000 Series Router and even create
an electrical hazard by causing power surges through power lines into installed equipment. These
problems are rare, but could be catastrophic.
To resolve these problems, you need specialized knowledge and equipment, which could consume
substantial time and money. However, you should ensure that you have a properly grounded and shielded
electrical environment, paying special attention to the need for electrical surge suppression.

Services Routers.
