NOTE: To determine cable length, add the conductor and shield capacitance specified above to determine the total wire capacitance. For example, if you are using a Belden wire (Part Number 9671), add the conductor capacitance of 30 pF/ft and the shield capacitance of 55 pF/ft for a total capacitance of 85 pF/ft. If you are operating at a rate of 19.2 kbps, the maximum allowable cable length to attain throughput of 19.2 kbps is 28.24 feet. Multiplying 28.24 by the total cable capacitance of 85 pF/ft yields a maximum allowable cable capacitance of 2410.4 pF, which is acceptable in accordance with Table B-4.

DTE Cable Diagnostics

This section helps determine whether there is a problem with a DTE cable. Perform the following steps before continuing with installation. If you continue to experience problems with data transmission after choosing a cable and running the diagnostics in this section, the problem may be with your DTE or modem.

If the modem is not installed at a host site, perform the following steps:

1)Enable the AT ACU (if not already enabled) with async echo on (reinitializing the modem will also enable the AT ACU with async echo set to on). Ensure that rate and parity of the modem and the DTE are identical.

2)Send data to the modem from the DTE. NOTE: Do not substitute test equipment for the DTE, as the DTE's receivers/drivers are used in this test.

3)If echoed data from the modem (as received by the DTE) matches the transmitted message, send the status screen (AT*ST<CR>) command.

4)If there are no errors in either of the previous tests, the cable is appropriate for your application.
