Loss of Frame. The inability to maintain frame synchronization.

Loss of Frame Count. A count of the number of LOFs declared.

Used to test various portions of a data link in order to isolate an equipment or data line

problem. A diagnostic procedure that sends a test message back to its origination point.

Loss Of Signal. The T1 line condition where there are no pulses.

Line Signal Detect. An EIA-lead standard for V.24 circuit CT 109; an output signal

(DCE-to-DTE).

The device that queries agents for management information, or receives unsolicited SNMP

trap messages indicating the occurrence of specific events.

Management Information Base. The set of variables a device running SNMP maintains.

Standard, minimal MIBs have been defined, and vendors often have private enterprise

MIBs. In theory, any SNMP manager can talk to any SNMP agent with a properly defined

MIB. MIB-II refers to an extended management database that contains variables not

defined in the original MIB I.

A method for interleaving several access channels onto a single circuit for transmission

over the network.

The T1 network interface connector on the rear panel of the DSU/CSU.

Network Management System. A computer system used for monitoring and controlling

network devices.

A connection or switching point on the network.

No Signal. A network-reported condition.

A specific item within the Management Information Base (MIB).

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.

A data network circuit with one control and one tributary device.

Point-to-Point Protocol. A link-layer protocol used by SNMP.

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.

Quasi-Random Signal Source. Test pattern that approximates live data that can be

monitored for logic errors (on the network and the data port).

A reinitialization of the device that occurs at power-up or in response to a reset command.

Request for Comments. The set of documents that describes the standard specifications

for the TCP/IP protocol suite.

Routing Information Protocol. Specifies the routing protocol used between DSUs.

Receive Line Signal Detect. See CD.

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 protocols used.
