Synchronous Clock Source
Note:
n= 0, 1, or 2
0
Selects the source of the transmit clock for synchronous mode. In asynchronous mode,
the transmit and receive clocks are turned off. In synchronous mode, the clocks are turned
on with a frequency of 1200 Hz or faster corresponding to the speed selected for modem
operation.

x = Stored telephone number
None
Stores telephone dial string x in memory location.
&Z3 is the phone memory location for leased-line dial back up number.
Dial the stored number using the ATDS=n command.
Note: See also the #CBSn command.
Data Compression Control
n = 0, 1, 2, or 3
3
Enables or disables data compression negotiation. The modem can only perform data
compression on an error-corrected link.
%C0 Disables data compression.
%C1 Enables MNP 5 data compression negotiation.
%C2 Enables V.42bis data compression negotiation.
%C3 Enables both V.42bis and MNP 5 data compression negotiation.
Note:
&Z3 is the phone memory location for leased-line dial back up number (not for the
MT5656ZDX and the MT5656ZDX-V).
For use with MT5600BA and MT5600BR only.
This command controls both V.42bis and MNP-5 data compression, whereas the

loaded instead of the factory defaults at power-on (if &Y1 is set) and by the ATZ1
command.
See also the Z, &F, and &Y commands.
Synchronous Online (&M1) must be enabled before you can set the synchronous
clock.
Selects internal timing. The modem generates the transmit clock signal and applies
it to the TXCLK output at the serial interface.
Selects external timing. The local DTE sources the transmit clock signal on the
XTCLK input of the serial interface. The modem applies this clock to the TXCLK
output at the serial interface.
Selects slave receive timing. The modem derives the transmit clock signal from the
incoming carrier and applies it to the TXCLK output at the serial interface.
Select profile 0 to be loaded on power-up.
Select profile 1 to be loaded on power-up.
See also the &W and Z commands.
&E14 and &E15 commands control only V.42bis data compression. The command
in effect is the one last entered.
