ACCULINK 316x DSU/CSU
E-14 January 1997 3160-A2-GB21-50
Asynchronous Port Table,
“rs232AsyncPortParity”
(rs232AsyncPortEntry 4)
This object specifies the parity used by the port. Only
the following values are supported by the DSU/CSU.
• none(1) – No parity bit.
• odd(2) – Odd parity. Supported on the COM and
MODEM ports only.
• even(3) – Even parity. Supported on the COM and
MODEM ports 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 DSU/CSU.
• disabled(2) – Autobaud is not supported.
Synchronous Port Table, RS-232-like MIB
The synchronous port table contains an entry for each
of the synchronous data ports and the MODEM or COM
port when the port is configured for synchronous
operation. For the DSU/CSU, 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 DSU/CSU.
• 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 DSU/CSU.
• 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 DSU/CSU.
• 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 DSU/CSU.
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 DSU/CSU.
• 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 DSU/CSU.
• on(2) – The signal is asserted.
• off(3) – The signal is not asserted.
