T1 ESF CSU ACE

 

 

SDLC

synchronous data link control. A link-level communications protocol used in an international business machines (IBM) systems Network Architecture (SNA) network that manages synchronous, code-transparent, serial information transfer over a link connection. SDLC is a subset of the HDLC protocol developed by ISO.

service

The provision of telecommunications to customers by a common carrier, administration, or private operating agency, using voice, data, and/or video technologies.

SNMP

simple network management protocol. A control and reporting scheme widely used to manage devices from dif- ferent vendors. SNMP operates on top of the Internet protocol.

SR

data set ready. A signal on the EIA-232 interface that indicates if the communications is connected and ready to start handshaking control signals so communications can begin.

statistical multiplexing

Interleaving the data input of two or more devices on a single channel or access line for transmission through a frame relay network. Interleaving of data is accomplished using the DLCI.

switched network

The network of dial-up telephone lines using circuit switching to provide communications services to network users.

synchronous

Communications in which the timing is achieved by sharing a single clock. Each end of the transmission syn- chronizes itself with the use of clocks and information sent along with the transmitted data.

T1

Transmission rate of 1.544 Mbps on T1 communication lines. A T1 facility carriers a 1.544 Mbps digital signal. Also referred to as digital signal level 1 (DS-1). See also E1.

trunk line

A communications line connecting two frame relay switches to each other.

VT100

A non-intelligent terminal or terminal emulation mode used for asynchronous communications. Used to config- ure the T1 ESF CSU ACE.
