### Description

```asn1
mdmDTESyncTimingSource OBJECT-TYPE
SYNTAX INTEGER {internal(1), external(2), loopback(3), network(4)}
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"The clock source for synchronous transmissions. If set to
internal(1), the modem is the clock source and sends the
clock signals to the DTE. If set to external(2), the
transmit clock signals are provided by the DTE. If
loopback(3), the modem receiver clock is used for the
transmit clock. If network(4), the clock signals are
supplied by the DCE interface.
If the modem is not in synchronous mode, setting this object
will have no effect on the current operations of the modem."
REFERENCE
"V.58 transmitClockSource"
DEFVAL {internal}
```

**Classification:** MIB object for network management
