Synchronous Port Table, RS-232-like MIB
The synchronous port table contains an entry for each
of the synchronous data ports and the COM port when the
port is configured for synchronous operation. For the
E1 NTU, the entries in the table that are counters
(rs232SyncPortEntry 3–7) are used to collect statistics and
are not supported.
Synchronous Port Table –
“rs232SyncPortClockSource”
(rs232SyncPortEntry 2)
This object specifies the clock source for the port. Only
the following values are supported by the E1 NTU.
•
internal(1) – The port uses an internal clock.
•
external(2) – The port uses an external clock.
Input Signal Table, RS-232-like MIB
This table contains entries for the input signals that can
be detected by the unit for each of the synchronous data
ports.
Input Signal Table – “rs232InSigName”
(rs232InSigEntry 2)
This object contains the identification of a hardware
input signal. Only the following values are supported by
the E1 NTU.
•
rts(1) – Request-To-Send.
•
dtr(4) – Data Terminal Ready.
Input Signal Table – “rs232InSigState”
(rs232InSigEntry 3)
This object contains the current signal state. Only the
following values are supported by the E1 NTU.
•
on(2) – The signal is asserted.
•
off(3) – The signal is not asserted.
Input Signal Table – “rs232InSigChanges”
(rs232InSigEntry 4)
This object is not supported by the E1 NTU.
Output Signal Table, RS-232-like MIB
This object contains entries for the output signals that
can be asserted by the unit for each of the synchronous
data ports.
Output Signal Table – “rs232OutSigName”
(rs232OutSigEntry 2)
This object contains the identification of a hardware
output signal. Only the following values are supported by
the E1 NTU.
•
cts(1) – Clear-To-Send.
•
dsr(4) – Data Set Ready.
Output Signal Table – “rs232OutSigState”
(rs232OutSigEntry 3)
This object contains the current signal state. Only the
following values are supported by the E1 NTU.
•
on(2) – The signal is asserted.
•
off(3) – The signal is not asserted.
Output Signal Table – “rs232OutSigChanges”
(rs232OutSigEntry 4)
This object is not supported by the E1 NTU.
Generic-Interface Extension
MIB (RFC 1229)
This generic-interface MIB is an experimental MIB
that provides extensions to the generic interface group
defined in MIB II. This MIB describes three tables:
•
Generic Interface Extension Table
•
Generic Interface Test Table
•
Generic Receive Address Table
Only the generic interface test table is supported by the
E1 NTU. This table is supported for the network interface
only.
