4.15.2 SBUS Bandwidth Considerations
Each SBUS device generates a certain amount of traffic on the SBUS. Generally, the amount of traffic generated depends on the type of
SBUS device. To help you figure out the SBUS bandwidth usage of a given collection of devices, a tool is available on the Silent Knight
website (www.silentknight.com). The tool will serve as a guide to help determine how heavily loaded an SBUS is with respect to bandwidth.
We recommend you use this tool if you plan to have more than eight SBUS devices per SBUS. Remember to include devices that are on
5895XL SBUS repeaters in your list of devices for SBUS bandwidth calculations. Refer to Section 4.6.1.
4.16 Telephone Connection
Connect the telephone lines as shown in Figure 4.43. The 7860 phone cord is available from Silent Knight for this purpose. If you do not use
the model 7860 to connect to the phone lines, the wire used for the connection must be 26 AWG or larger diameter wire.
A number of programmable options are available for customizing telephone lines. These options are described in "Phone Lines" on
page 104.
