Circuit Assurance

Choosing option 2 in the Software Switch Menu takes you to the Circuit Assurance Menu (below). On dedicated (DDS) circuits, the transmitter and the CTS output can be configured to go ON only when a working communication circuit is established. If you use Circuit Assurance with DDS services, enable it on only one end of the communication link. For Switched-56 service, enable Circuit Assurance on both ends of the circuit. When Circuit Assurance is disabled, the transmitter and CTS operate without regard to the receiver state.

Force RTS

Choosing option 3 in the Software Switch Menu takes you to the RTS Menu (below). The RTS input can be forced ON, ignoring the RTS signal from the DTE. RTS controls the transmitter by sending either user data (when high) or idle code (when low). On a Model 2510 or 2520, Force RTS should be enabled for Switched-56 operation.

Note: When the Line Rate (Software Switch Menu option 1) is 64 kbps, RTS is always forced ON, regardless of the Force RTS switch setting.

Character Length

Choosing option 4 in the Software Switch Menu takes you to the Character Length Menu (below). In asynchronous data format, the Model 2500 Series supports 10-bit and 11-bit character lengths. Set this option according to the characteristics of the data being transmitted.

DTE Data Format

Choosing option 5 in the Software Switch Menu takes you to the Data Format Menu (below). This option controls whether an async-to- sync conversion is performed between the DTE and the Model 2500 Series. (Data is always transferred synchronously between two Model 2500 Series units.) For an asynchronous DTE, select the asynchronous data format1,2; for a synchronous DTE, select the synchronous data format.

Note1: The async rate of 57.6 kbps is supported at the 56 kbps line rate, provided the DTE equipment transmits two stop bits. Two stop bits can be configured on most DTE equipment. This extra stop bit reduces the DTE’s effective data rate by a few percent to allow synchronization with the 56 kbps line speed. Set the Model 2500 Series for two stop bits by selecting “11 bit character length” in the Character Length Menu.
