Anti-Stream Timer

The anti-stream timer protects multidrop networks from a drop that is continuously transmitting. If the terminal keeps RTS raised for more than 30 seconds, the timer forces RTS off internally. This allows the rest of the multidrop network to resume operation. The CSU/DSU remains in the forced-off condition until the terminal drops RTS.

4.2 CONFIGURATION USING SOFTWARE SWITCHES

The Model 2500 Series CSU/DSUs can be soft configured using a VT100 terminal or similar RS-232 DTE with terminal emulation. To use software switches for configuration, follow these steps:

1)Connect the serial RS-232C port of the terminal to the modular EIA-561 control port on the front panel of the Model 2500 Series. To construct an RS-232 to EIA-561 patch cable, refer to the control

port pinout diagram in Appendix D.

2) Power up the terminal and set its RS-232C port as follows:

9600 baud

8 data bits, 1 stop bit, no parity local echo

CR = CR/LF on inbound data ANSI, VT-100 emulation

3)Key menu, then press [RETURN]. The Model 2500 Series Main Menu should then display on the terminal screen (see below).
