Chapter 2 Planning Your Installation

Distance Limitations for Interface Cables

Before you connect a device to the synchronous serial port (labeled SERIAL 0), you need to know the following:

•Type of device, DTE or DCE, you are connecting to the synchronous serial interface

•Type of connector, male or female, required to connect at the device

•Signaling standard required by the device

Distance Limitations for Interface Cables

When planning your installation, consider distance limitations and potential electromagnetic interference (EMI) as defined by the Electronic Industries Association (EIA). Distance limitation information is included for the following IAD ports:

•Fast Ethernet Maximum Distance, page 2-4

•T1/E1-WAN Port Maximum Distances, page 2-4

•Serial Port Maximum Distances (WIC/VIC Cards), page 2-4

•T1/E1-PBX Digital Voice Port Maximum Distances, page 2-6

•FXS Analog Voice Port Maximum Distance, page 2-6

•FXO Analog Voice Port Maximum Distance, page 2-6

Fast Ethernet Maximum Distance

The maximum segment distance for Fast Ethernet is 330 feet (100 meters) (specified in IEEE 802.3).

T1/E1-WAN Port Maximum Distances

Table 2-1shows the distance limitations for T1/E1 signals (specified in ANSI T1.403).
