Paradyne 317x E1 manual General Port Table ± ªrs232PortTypeº Object rs232PortEntry

ACCULINK 317x E1 DSU/CSU

General Port Table ± ªrs232PortTypeº Object (rs232PortEntry 2)

This object is used to identify the port's hardware type. Only the following values are supported by the E1 DSU/CSU.

•rs232(2) ± Used to identify the AUX and COM ports.

•rs422(3) ± Used to identify synchronous data ports that are configured as EIA-530A or RS-449.

•v35(5) ± Used to identify synchronous data ports that are configured as V.35.

General Port Table ± ªrs232PortOutSpeedº Object (rs232PortEntry 6)

This object contains the port's output speed in bits per second. For the E1 DSU/CSU, the rs232PortInSpeed object has the same value as the rs232PortOutSpeed object. The input speed of a synchronous data port is determined by the channel configuration and cannot be changed through this object. Thus, for the synchronous data ports, this object is read-only. The input speed of the AUX or COM port is the currently configured speed. Setting of this value for the AUX or COM port causes the configured port speed to be changed.

General Port Table ± ªrs232PortInSigNumberº Object (rs232PortEntry 3)

This object contains the number of input signals contained in the input signal table. This is the number of signals that can be detected. This number is 2 for the synchronous data ports and 0 for the AUX and COM ports.

General Port Table ± ªrs232PortOutSigNumberº Object (rs232PortEntry 4)

This object contains the number of output signals contained in the output signal table. This is the number of signals that can be asserted. This number is 2 for the synchronous data ports and 0 for the AUX and COM ports.

Asynchronous Port Table, RS-232-like MIB

The asynchronous port table contains an entry for the AUX or COM port when the port is configured for asynchronous operation. For the E1 DSU/CSU, the entries in the table that are counters (rs232AsyncPortEntry 6±8) are used to collect statistics and are not supported.

Asynchronous Port Table, ªrs232AsyncPortBitsº (rs232AsyncPortEntry 2)

This object specifies the number of bits in a character. Only the following values are supported by the E1 DSU/CSU.

•7 ± 7-bit characters. Supported on the COM port only.

•8 ± 8-bit characters.

General Port Table ± ªrs232PortInSpeedº Object (rs232PortEntry 5)

This object contains the port's input speed in bits per second. For the E1 DSU/CSU, the rs232PortInSpeed object has the same value as the rs232PortOutSpeed object. The input speed of a synchronous data port is determined by the channel configuration and cannot be changed through this object. Thus, for the synchronous data ports, this object is read-only. The input speed of the AUX or COM port is the currently configured speed. Setting of this value for the AUX or COM port causes the configured port speed to be changed.

Asynchronous Port Table, ªrs232AsyncPortStopBitsº (rs232AsyncPortEntry 3)

This object specifies the number of stop bits supported. Only the following values are supported by the E1 DSU/CSU.

•one(1) ± One stop bit.

•two(2) ± Two stop bits. Supported on the COM port only.

•one-and-half(3) ± One and a half stop bits. Supported on the COM port only.
