Port-Level Indicators

Description

 

 

ACT LED (Amber)

A steady amber LED indicates a link is detected, but there is an issue

 

 

inhibiting traffic. A blinking amber LED means traffic is flowing.

 

 

LINK LED (Green)

A steady green LED indicates that a link is detected, but there is no

 

 

traffic. A blinking green LED flashes at a rate proportional to the level

 

 

of traffic being received and transmitted over the port.

 

 

Both ACT and LINK LED

Unlit green and amber LEDs indicate no traffic.

OFF

 

 

 

 

 

2.4 CE-MR-6 Card

This section describes the features and functions of the CE-MR-6 Ethernet card. This card is compatible with the Cisco ONS 15310-MA SDH.

The CE-MR-6 card provides six IEEE 802.3-compliant 10/100/1000-Mbps Gigabit Ethernet ports at the ingress. At the egress, the CE-MR-6 card provides an integrated Ethernet over SDH mapper with six virtual ports to transfer Ethernet packets over an SDH network.

The CE-MR-6 card uses pluggable Small Form-Factor Pluggable Interface Converters (SFPs) to transport Ethernet traffic over an SDH network. SFP modules are offered as separate orderable products for flexibility. For details, see the “2.8 SFP Modules” section on page 2-19.

The Ethernet frames are encapsulated using the ITU-T generic framing procedure (GFP) [with or without cyclic redundancy check (CRC)] or LAN extension (LEX), the point-to-point protocol (PPP) with high-level data link control (HDLC).

The Ethernet ports automatically configure to operate at either half or full duplex and can determine whether to enable or disable flow control. The Ethernet ports can also be oversubscribed using flow control.

The CE-MR-6 card supports the link capacity adjustment scheme (LCAS), which allows hitless dynamic adjustment of SDH link bandwidth. The CE-MR-6 card's LCAS is hardware-based, but the CE-MR-6 also supports software LCAS (SW-LCAS). This makes it compatible with ML-Series cards, which support only SW-LCAS, along with the CE-100T-8 cards. The CE-MR-6 card also supports the non link capacity adjustment scheme (no-LCAS). The CE-MR-6 card supports both flexible and fixed VCAT groups (VCG).

Note The SW-LCAS is not supported on CE-MR-6 cards for interoperation with the CE-100T-8 and ML-MR-10 cards.

Note The CE-MR-6 card does not support interoperation between the LCAS and non-LCAS circuits.

The Ethernet frames can be mapped into:

E1X1 G.707-based high-order virtual concatenated (HO VCAT) payloads

VC4-nv, where n is 1 to 7

VC3-nv, where n is 1 to 21

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.
