COMSPHERE 3800 Series Modems

pulse dialing	One of two dialing methods, in which telephone numbers are sent as pulses (brief
	changes in voltage or current intensity) across the telephone line. Rotary telephones use
	pulse dialing.
register	A part of the modem’s memory that contains values that determine the modem’s
	operating characteristics.
Remote	A branch of the Top-Level menu that permits access to the DCP of another modem.
remote loopback	A test that sends a signal to the remote modem to test the local modem, the remote
	modem, and the circuit between them.
remote mode indicator	An inverse video that indicates the modems are operating in Remote mode.
result code	An asynchronous message (in either numbers or words) that the modem sends to the
	DTE after executing or trying to execute a command.
Return to Dial	A function available when in Dial Backup mode that allows the modem to switch to
	dial-line operation when currently on leased lines.
RJ11	A type of 6-position jack normally used with permissive dial networks and telephone
	sets.
RJ21	A type of 50-position jack normally used with permissive dial networks providing the
	appropriate conductors for up to eight telephone lines.
RJ27	A type of 50-position jack normally used with programmable dial networks providing
	the appropriate conductors for up to eight telephone lines.
RJ45	A type of 8-position jack normally used with programmable dial networks.
rotary	A TELCO service whereby multiple lines to a customer premises share a common
	telephone number.
SDCP	Shared Diagnostic Control Panel. An optional user interface similar to the front panel of
	a Model 3810 or 3820 modem that attaches to the front of a COMSPHERE 3000 Series
	Carrier. Installed at eye level into one COMSPHERE 3000 Series Carrier, it controls and
	monitors modems in all the carriers in the cabinet. A single SDCP can control up to 8
	carriers, with a total of 128 modems.
SDU	Shared Diagnostic Unit. A circuit card installed in Slot 0 of the COMSPHERE 3000
	Series Carrier that provides an interface between an optional SDCP and/or network
	management and Model 3811 modems.
Select key	An SDCP key that allows the selection of a specific card slot in the COMSPHERE
	3000 Series Carrier.
serial transmission	A way of transmitting data in which bits are sent sequentially one at a time.
Shared Diagnostic Unit	A circuit card that plugs into a dedicated slot in the COMSPHERE 3000 Series Carrier to
(SDU)	provide the SDCP and network management interfaces to the dial modems in the carrier.
	It translates the network management protocol to the devices in the carrier and routes
	incoming messages to the appropriate slots.
S-registers	Internal storage areas that contain information affecting the modem parameters.
