SX-200 General Information Guide
Data: DTRX Help
The Data Transceiver (DTRX) provides on-line help.
Data: DTRX Hotline
A dataset can be programmed to connect automatically to a predetermined destination when
a user originates a DTRX data call.
Data: DTRX Messages
The Data Transceiver (DTRX) provides a number of messages to inform the user of call
progress and error conditions.
Daylight Savings Time Adjustment
This feature allows you to program the system to automatically set the system clock
•
ahead for daylight savings time
•
back for standard time.
You program the month, day, and hour of the time changes, and the length of the time
adjustment through CDE each year. The system automatically performs the time changes. A
system reset is not required for a time change to take effect.
Device Interconnection Control
The Device Interconnection Control feature provides a means of disallowing connection
between devices of different types. The feature is primarily intended to control trunk
interconnections but applies to other devices as well. This is intended to provide a method of
meeting interconnection restrictions imposed by various regulatory authorities. The checks
apply when a device calls another device, when a transfer (supervised or unsupervised) is
attempted and when the console attempts to perform operations on devices.
See Flash Control for details on controlling the ability of extensions to flash when extensions
are involved with trunk calls.
Dial Tone Disable
Assigning this feature to a dial-in trunk suppresses dial tone on an incoming trunk call. If this
feature is assigned to an extension, the extension does not receive dial tone when dialing is
initiated.
Dial Tone - Discriminating
An extension that has a feature enabled that prevents calls from ringing the extension hears a
distinct dial tone (350/440 Hz, 400 ms on, 100 ms off for six cycles, followed by continuous
tone) when going off-hook to make a call. These features include Do Not Disturb, Call
Forwarding - Always, and Call Forwarding - I Am Here.
