Parameter

 

Definition

 

 

 

HP-EB

 

High-Order Path Errored Block (HP-EB) indicates that one or more bits are

 

 

in error within a block.

 

 

 

HP-ES

 

High-Order Path Errored Second (HP-ES) is a one-second period with one

 

 

or more errored blocks or at least one defect.

 

 

 

HP-ESR

 

High-Order Path Errored Second Ratio (HP-ESR) is the ratio of errored

 

 

seconds to total seconds in available time during a fixed measurement

 

 

interval.

 

 

 

HP-NPJC-Pdet

 

High-Order, Negative Pointer Justification Count, Path Detected

 

 

(HP-NPJC-Pdet) is a count of the negative pointer justifications detected

 

 

on a particular path on an incoming SDH signal.

 

 

 

HP-NPJC-Pdet

 

High-Order Path Negative Pointer Justification Count, Path Detected

 

 

(HP-NPJC-Pdet) is a count of the negative pointer justifications detected

 

 

on a particular path on an incoming SDH signal.

 

 

 

HP-NPJC-Pgen

 

High-Order, Negative Pointer Justification Count, Path Generated

 

 

(HP-NPJC-Pgen) is a count of the negative pointer justifications generated

 

 

for a particular path.

 

 

 

HP-PJCDiff

 

High-Order Path Pointer Justification Count Difference (HP-PJCDiff) is

 

 

the absolute value of the difference between the total number of detected

 

 

pointer justification counts and the total number of generated pointer

 

 

justification counts. That is, HP-PJCDiff is equal to

 

 

(HP-PPJC-PGenHP-NPJC-PGen)(HP-PPJC-PDetHP-NPJC-PDet).

 

 

 

HP-PJCS-Pdet

 

High-Order Path Pointer Justification Count Seconds (HP-PJCS-PDet) is a

 

 

count of the one-second intervals containing one or more HP-PPJC-PDet

 

 

or HP-NPJC-PDet.

 

 

 

HP-PJCS-Pgen

 

High-Order Path Pointer Justification Count Seconds (HP-PJCS-PGen) is

 

 

a count of the one-second intervals containing one or more HP-PPJC-PGen

 

 

or HP-NPJC-PGen.

 

 

 

HP-PPJC-Pdet

 

High-Order, Positive Pointer Justification Count, Path Detected

 

 

(HP-PPJC-Pdet) is a count of the positive pointer justifications detected on

 

 

a particular path on an incoming SDH signal.

 

 

 

HP-PPJC-Pgen

 

High-Order, Positive Pointer Justification Count, Path Generated

 

 

(HP-PPJC-Pgen) is a count of the positive pointer justifications generated

 

 

for a particular path.

 

 

 

HP-SES

 

High-Order Path Severely Errored Seconds (HP-SES) is a one-second

 

 

period containing 30 percent or more errored blocks or at least one defect.

 

 

SES is a subset of ES.

 

 

 

HP-SESR

 

High-Order Path Severely Errored Second Ratio (HP-SESR) is the ratio of

 

 

SES to total seconds in available time during a fixed measurement interval.

 

 

 

HP-UAS

 

High-Order Path Unavailable Seconds (HP-UAS) is a count of the seconds

 

 

when the VC path was unavailable. A high-order path becomes unavailable

 

 

when ten consecutive seconds occur that qualify as HP-SESs, and it

 

 

continues to be unavailable until ten consecutive seconds occur that do not

 

 

qualify as HP-SESs.

15310-MA specifications

Cisco Systems has established itself as a leader in the networking domain, offering a wide array of solutions to meet the needs of modern businesses. Among its impressive product lineup are the Cisco 15310-CL and 15310-MA routers, designed to provide advanced network performance and reliability.

The Cisco 15310-CL is a versatile platform that primarily serves as a carrier-class router aimed at supporting high-speed data and voice services. It is built to handle the demands of large enterprises and service providers, offering a robust design that ensures maximum uptime and performance. One of its standout features is its modular architecture, which enables users to customize their configurations based on specific application needs. This scalability allows for future expansion without the need for a complete hardware overhaul.

Key technologies integrated into the Cisco 15310-CL include high-density Ethernet interfaces and a comprehensive suite of Layer 2 and Layer 3 protocol support. The device is capable of supporting multiple types of connections, including TDM, ATM, and Ethernet. This flexibility makes it an ideal choice for organizations that require seamless migration between various service types. Moreover, with features such as MPLS (Multiprotocol Label Switching) support and advanced Quality of Service (QoS) mechanisms, the router ensures that critical applications receive the necessary bandwidth and low latency required for optimal performance.

In contrast, the Cisco 15310-MA focuses on access solutions, providing a cost-effective entry point for businesses looking to enhance their network capabilities. It is well-suited for smaller offices or branch locations that need reliable connectivity without the expense and complexity associated with larger systems. The device supports a range of access methods and provides essential features like firewall capabilities, VPN support, and comprehensive security measures to protect sensitive data.

Both models benefit from Cisco's commitment to security and manageability, offering features like enhanced encryption protocols and user authentication mechanisms that help safeguard networks against threats. Additionally, they can be managed through Cisco’s intuitive software tools, simplifying configuration and monitoring tasks for IT administrators.

The Cisco 15310-CL and 15310-MA are ideal solutions for businesses seeking to enhance their network infrastructure, ensuring firms can keep pace with evolving technology demands while maintaining a focus on security and performance. Their combination of advanced features, modular capabilities, and robust support makes them valuable assets in the networking landscape.
