### Description

```asn1
hneSysSyncTimingMode OBJECT-TYPE
SYNTAX INTEGER { internal(1), line(2), external(3) }
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"An identification of the source from which timing is derived by
the working sync module within the HNE. Possible values are:

internal(1) - the internal oscillator on the sync module will be
used as the master clock for system synchronization.
line(2) - the sync module is synchronizing with the receive
line timing from a signal received by an LIU.
external(3) - the Building Integrated Timing System (BITS)
available on a T1 line plugged into an LIU will be
used as the master clock for system synchronization."
DEFVAL { internal }
