Synchronous Port Table Objects
The
Synchronous Port Table Objects contains an entry for the synchronous user
data port and the Management port when this port is configured for synchronous
operation. For this unit, entries in the table that are counters (rs232SyncPortEntry
3–7) are used to collect statistics only and are not supported. Clarification for
objects contained in this table as it applies to the unit is provided below.
Table C-13.

Object, OID, Access
Description
Setting/Contents
rs232SyncPortClock-
Source
(rs232SyncPortEntry 2 )
1.3.6.1.2.1.10.33.4.1.2
read-write
Specifies the clock source
for the port.
Supports only the following
values:
internal(1) – The port uses an
internal clock.
external(2) – The port uses an
external clock.
rs232SyncPortRole
(rs232SyncPortEntry 8 )
1.3.6.1.2.1.10.33.4.1.8
read-write
Specifies whether this
device interface is a DTE or
DCE.
Supports only the following
value:
dce(2) – The port acts as a
DCE.
rs232SyncPortEncoding
(rs232SyncPortEntry 9 )
1.3.6.1.2.1.10.33.4.1.9
read-write
Specifies the bit encoding
technique that this port
uses.
Supports only the following
value:
nrz(1) – The port uses
non-return to zero encoding.
nrzi(2) – The port uses
non-return to zero-inverted
encoding. This corresponds to
the inverted transmit and
receive data relationship.
rs232SyncPortRTS-
Control
(rs232SyncPortEntry 10 )
1.3.6.1.2.1.10.33.4.1.10
read-write
Specifies the method used
to control the RTS signal.
Supports only the following
values:
controlled(1) – For User Data
port, this value is used when
the Data Port option Carrier
Control by RTS is set to
Switched.
constant(2) – For User Data
port, this value is used when
the Data Port option Carrier
Control by RTS is set to
Constant. This is the only valid
value for the Management
port.
rs232SyncPortRTSCTS-
Delay
(rs232SyncPortEntry 11 )
1.3.6.1.2.1.10.33.4.1.11
read-write
Reports the interval (in
milliseconds) that the port
waits after RTS is asserted
before asserting CTS.
Supports only the following
read-only values:
0 – The port does not have to
wait. Only valid for
Management port.
