Glossary

link layer protocol

The protocol that regulates the communication between two network nodes.

LL

Local Loopback. An EIA-lead standard for V.24 circuit CT 141; an input signal

 

(DTE-to-DCE).

loopback

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.

LSD

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

 

(DCE-to-DTE).

manager (SNMP)

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

 

trap messages indicating the occurrence of specific events.

MIB

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.

multiplexing

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

 

over the network.

NMS

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

 

network devices.

node

A connection or switching point on the network.

non-latching

A loopback that is not maintained unless network loopback codes are interspersed with the

loopback

test data. A non-latching loopback can only be initiated or terminated by the 56 kbps

 

network service provider.

NS

No Signal. A network-reported condition.

object (SNMP)

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

OOF

Out Of Frame. An error condition in which frame synchronization bits are in error. A

 

network-reported condition.

OOS

Out of Service. A digital network trouble signal.

PAD

Packet Assembler/Disassembler.

point-to-point circuit

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

PPP

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

protocol

The rules that govern how devices exchange information on a network. It covers timing,

 

format, error control, and flow control during data transmission.

PSTN

Public Switched Telephone Network. A network shared among many users who can use

 

telephones to establish connections between two points.

reset

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

RFC

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

 

for the TCP/IP protocol suite.

RIP

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

RLSD

Receive Line Signal Detect. See CD.

router

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.

7612 SNMP DSU specifications

The Paradyne 7612 SNMP DSU (Data Service Unit) is a robust and versatile device designed for effective communication in data networks. This device is particularly suited for businesses that require reliable connectivity to support their operations. The 7612 integrates advanced technologies that enhance performance, scalability, and ease of management.

One of the main features of the Paradyne 7612 is its support for SNMP (Simple Network Management Protocol), which allows for comprehensive monitoring and management of network devices. This capability ensures that network administrators can easily track performance metrics and troubleshoot issues in real time, thereby minimizing downtime and enhancing overall operational efficiency.

The 7612 also provides multiple interface options, including T1/E1 and fractional T1, enabling users to select the most suitable bandwidth for their specific requirements. With full duplex capabilities, the device can handle simultaneous data transmission and reception, ensuring efficient communication and high throughput.

In terms of security, the Paradyne 7612 incorporates features such as port security and access control lists (ACLs). These measures protect the network from unauthorized access, ensuring that sensitive data remains secure during transmission. Additionally, the DSU incorporates intelligent diagnostic features, such as loopback testing and error monitoring, enabling proactive identification and resolution of network issues.

The device is built with a modular design, allowing for easy upgrades and scalability as business needs grow. This flexibility ensures that organizations can adapt their network infrastructure without the need for significant overhauls or extensive downtime.

The Paradyne 7612 also boasts an intuitive web-based user interface, simplifying configuration and management tasks. Network administrators can access settings and monitor performance from any location, streamlining network management processes.

With a focus on reliability, the 7612 is designed to operate in various environmental conditions, offering features such as extended temperature ranges and robust construction, making it suitable for deployment in both indoor and outdoor settings.

In summary, the Paradyne 7612 SNMP DSU stands out in the realm of data communication devices with its advanced SNMP capabilities, versatile interface options, robust security features, modular design, and user-friendly management interface. These characteristics make it an ideal solution for enterprises seeking to maintain reliable, scalable, and secure data communication networks.
