synchronous data ports and 0 for the AUX and COM
ports.
General Port Table – “rs232PortOutSigNumber”
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.
General Port Table – “rs232PortInSpeed”
Object (rs232PortEntry 5)
This object contains the port’s input speed in bits per
second. For the E1 NTU, 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 – “rs232PortOutSpeed”
Object (rs232PortEntry 6)
This object contains the port’s output speed in bits per
second. For the E1 NTU, 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, 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 NTU, the entries in
the table that are counters (rs232AsyncPortEntry 6–8) are
used to collect statistics and are not supported.
Asynchronous Port Table, “rs232AsyncPortBits”
(rs232AsyncPortEntry 2)
This object specifies the number of bits in a character.
Only the following values are supported by the E1 NTU.
•7 – 7-bit characters. Supported on the COM port
only.
•8 – 8-bit characters.
Asynchronous Port Table,
“rs232AsyncPortStopBits”
(rs232AsyncPortEntry 3)
This object specifies the number of stop bits supported.
Only the following values are supported by the E1 NTU.
•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.
Asynchronous Port Table,
“rs232AsyncPortParity”
(rs232AsyncPortEntry 4)
This object specifies the parity used by the port. Only
the following values are supported by the E1 NTU.
•none(1) – No parity bit.
•odd(2) – Odd parity. Supported on the COM port
only.
•even(3) – Even parity. Supported on the COM port
only.
Asynchronous Port Table,
“rs232AsyncPortAutoBaud”
(rs232AsyncPortEntry 5)
This object specifies the ability to automatically sense
the input speed of the port. Only the following value is
supported by the E1 NTU.
•disabled(2) – Autobaud is not supported.
