Paradyne 3615, 3616 manual Rts

COMSPHERE DualFlow Data Service Units

point-to-point circuit	A data network circuit with one control and one tributary.
rate adaption	Used when the DSU or DBM operates at a speed greater than the DTE. This
	capability is enabled automatically when the port speed is set lower than the line
	speed.
router	A device that makes decisions about the paths network traffic should take and
	forwards that traffic to its destination. A router helps achieve interoperability and
	connectivity between different vendor's equipment, regardless of the protocols
	used.
RTS	The state of the Request-to-Send lead (V.24 circuit 105).
RXD	The state of the Received Data lead (V.24 circuit 104).
session disruptive	Application data may be disrupted when running a test, or running the test may
	cause the application session to be dropped or terminated. The result depends upon
	the time-out parameters, etc.
session-nondisruptive	Diagnostic messages with a duration of .5 seconds or less that are sent over the
diagnostics	primary data channel. These messages may interrupt customer data, causing errors
	requiring retransmission of data blocks. They should not, however, cause
	termination of the communication session.
Shared Diagnostic	A feature that allows carrier-mounted DSUs to share the same control panel.
Control Panel	Installed on one COMSPHERE 3000 Series Carrier, it controls and monitors the
(SDCP)	DSUs in all the carriers in the cabinet.
Shared Diagnostic Unit	A circuit card that plugs into a dedicated slot (slot 0) in the COMSPHERE 3000
(SDU)	Series Carrier to provide the shared diagnostic control panel (SDCP) and network
	management interfaces to the DSUs in the carrier. It translates the network
	management protocol to the devices in the carrier and routes incoming messages to
	the appropriate slots.
standalone	The Model 3615 DualFlow DSU that is designed for desktop operation. A
	standalone DSU can be configured as either a control or a tributary.
Switched 56 kbps	A service provided by local exchange and interexchange carriers (LECs and IECs)
digital service	that allow customers to use high-speed switched digital data capability without
	having to subscribe to private network services.
Switched mode	Used in networks containing only DualFlow DSUs, it is a mode of operation using
	control mode idle (CMI) and data mode idle (DMI) signaling in order to ensure
	protocol independence of primary data while trapping diagnostic data in the DSU.
training	The process of negotiating a communication rate between V.32 modems during call
	setup.
tributary	A DSU or DBM that is, for diagnostic purposes, at a logically subsidiary level in a
	hierarchical network. Tributary DSUs in a network receive data from the control
	DSU, as well as from any network management system present in the network.
TXD	The state of the Transmitted Data lead (V.24 circuit 103).
