7520-A2-GB20-20
A method for interleaving several access channels onto a single circuit for transmission
over the network.
A connection or switching point on the network.
A loopback that is not maintained unless network loopback codes are interspersed with the
test data. A non-latching loopback can only be initiated or terminated by the network
service provider.
No Signal. A network-reported condition.
Out Of Frame. An error condition in which frame synchronization bits are in error. A
network-reported condition.
Out of Service. A digital network trouble signal reported by the remote unit.
A data network circuit with one control and one tributary device.
The rules that govern how devices exchange information on a network. It covers timing,
format, error control, and flow control during data transmission.
Public Switched Telephone Network. A network shared among many users who can use
telephones to establish connections between two points.
A reinitialization of the device that occurs at power-up or in response to a reset command.
Receive Line Signal Detect. See CD.
A device that connects LANs by dynamically routing data according to destination and
available routes.
An EIA standard for the 25-pin DCE/DTE interface. Same as EIA-232.
Request to Send. An EIA-lead standard for V.24 circuit CT 105; an input signal
(DTE-to-DCE).
Receive. To obtain transmitted signals.
Received Clock. An EIA-lead standard for V.24 circuit CT 115; an output signal
(DCE-to-DTE).
Received Data. Pin 3 of the EIA-232 interface that is used by the DTE to receive data from
the modem. Conversely, the modem uses Pin 3 to transmit data to the DTE.
Data transmission that is synchronized by timing signals. Characters are sent at a fixed
rate.
Test Mode. An EIA-lead standard for V.24 circuit CT 142; an output signal ( DCE-to-DTE ).
AT&T Technical Reference 62310, DS0 Digital Local Channel: Description & Interface
Specification.
Transmit. To send signals from a device.
Transmit Clock. An EIA-lead standard for V.24 circuit CT 114; an output signal
(DCE-to-DTE).
Transmit Data. Pin 2 of the EIA-232 interface that is used by the DTE to transmit data to
the DSU. Conversely, the DSU uses Pin 2 to receive data from the DTE.
An ITU-T standard for a high-speed, 34-pin, DCE/DTE interface.
An ITU-T standard for local and remote diagnostic loopback tests.
An ITU-T standard for a data channel loopback (DCLB).
