If you configure your external modem to use leased lines and are
using Hayes compatible modems, the local modem should be
programmed to operate using either auto originate (ATO) or auto
answer (ATA) and the remote modem should be programmed to
operate using either auto answer or auto originate respectively. You
can program the Telplex to send out the auto originate or auto answer
AT commands to the external modem upon power-up , loss of DCD,
or manually using the Programmable Strings (see Section 4.2.2.3 ).
The factory default Line Type is Direct.

NOTE: This feature is applicable only if the Telplex is programmed to
use Modem Line Type.
The Telplex can be programmed to automatically send two separate
character strings up to 42 characters in length to the composite port.
Either string may be programmed to be sent on power-up, when
carrier drops out, on a combination of power-up or loss of carrier, or
manually only. Either string may be sent manually regardless of the
condition you choose. String 1 is sent manually by typing Control-U
while in Access Modem Command mode for multi-drop units (see
Section 4.3.5 ) or Local mode for standard units (see Section 4.3.1 )
and String 2 is sent manually by typing Control-V .
Programmable Strings typically consist of modem commands (e.g., to
instruct the local modem to dial out to a remote Telplex). If the string
consists of a dial command and a connection is made with the remote
Telplex, both units will go in MUX mode (see Section 4.3.3 ).
The default Programmable Strings are String 1 and String 2 both
null. The default sending condition is manual for both String 1
( Control-U ) and String 2 ( Control-V) .
