Glossary

agent

A software program housed within a device to provide SNMP functionality. Each SNMP

 

agent stores management information and responds to the manager's request.

aggregate

A single bit stream that combines two or more bit streams.

ASCII

American Standard Code for Information Interchange. A 7-bit code that establishes

 

compatibility between data services. ASCII is the standard for data transmission over

 

telephone lines.

asynchronous

A data transmission that is synchronized by a transmission start bit at the beginning of

 

a character (five to eight bits) and one or more stop bits at the end.

ATI

ASCII Terminal Interface. This feature allows a device to be controlled from an

 

asynchronous terminal or through a Telnet session.

autobaud mode

An operational mode in which the DSU forces automatic setting of the DDS line rate/speed

 

(56 kbps or 64 kbps) as soon as a valid DDS network signal is detected.

BPV

Bipolar Violation. A modified bipolar signaling method in which a control code is inserted.

CCA

Circuit Card Assembly. A printed circuit board to which separate components are attached.

CCITT

Consultative Committee on International Telegraphy and Telephony. See ITU.

CD

Carrier Detect. A signal indicating that energy exists on the transmission circuit.

 

Associated with Pin 8 on an EIA-232 interface.

channel

An independent data path.

CMI

Control Mode Idle. A control signal sent over the DDS line to indicate that no data is being

 

sent.

COM port

Communications port. A computer's serial communications port used to transmit to and

 

receive data.

configuration option

Device software that sets specific operating parameters for the DSU.

CPE

Customer Premises Equipment. Terminating equipment supplied by either the customer or

 

some other supplier that is connected to the telecommunications network (e.g., DSUs,

 

terminals, phones, routers, modems).

crossed pair

An alarm condition in which the DDS receive and transmit pairs are crossed.

CSU

Channel Service Unit. The function of the DSU that protects the equipment beyond it from

 

damage due to disturbances on the DDS network, and regenerates the DDS signal to

 

meet DDS specifications.

CTS

Clear to Send. An EIA-lead standard for V.24 circuit CT 106; an output signal

 

(DCE-to-DTE).

DCE

Data Communications Equipment. The equipment that provides the functions required to

 

establish, maintain, and end a connection. It also provides the signal conversion required

 

for communication between the DTE and the network.

DDS

Digital Data Service. Provides digital communication circuits.

DMI

Data Mode Idle. Refers to a sequence of ones transmitted or received on the DDS

 

network.
