Deployment Scenarios
The NM-CEM-4TE1 Cisco 4 Ports Expansion module is a versatile interface module that can be used in a variety of deployment scenarios. Here are some examples:
- Voice and Data Integration: The NM-CEM-4TE1 module can be used to integrate voice and data traffic in a network. It can be used to provide T1 or E1 connections for voice circuits, while also supporting data traffic over the same circuits. This can be useful in scenarios where both voice and data are required, such as in call centers or small offices.
- WAN Connectivity: The module can be used to provide WAN connectivity for a network. It supports multiple WAN protocols, such as PPP and Frame Relay, and can be used to connect to service provider networks or other WAN links.
- High-Speed Data Transfer: The NM-CEM-4TE1 module can be used to provide high-speed data transfer for a network. It supports data transfer rates of up to 2.048 Mbps, which can be useful in scenarios where large amounts of data need to be transferred quickly, such as in multimedia applications or large file transfers.
- Redundancy and Backup: The module can be used to provide redundancy and backup for a network. It can be used to provide backup connections in case of a failure of the primary connection, or to provide a redundant connection to ensure high availability of critical applications.
- Extension of LAN: The NM-CEM-4TE1 module can be used to extend the LAN of a network. It can be used to connect remote sites or branch offices to the main network, providing a cost-effective solution for network expansion.
High Availability and Redundancy Options
The NM-CEM-4TE1 Cisco 4 Ports Expansion module supports several high availability and redundancy options that help to ensure network uptime and minimize the risk of downtime. Here are some of the options:
- Link Aggregation Control Protocol (LACP): LACP is a protocol that allows multiple physical links to be combined into a single logical link. This can provide increased bandwidth and redundancy. The NM-CEM-4TE1 module supports LACP, allowing you to combine multiple T1 or E1 links into a single logical link.
- Redundant Power Supply: The Cisco routers that support the NM-CEM-4TE1 module also support redundant power supplies. This means that if one power supply fails, the other can take over, ensuring uninterrupted power to the router and the module.
- Hot Standby Router Protocol (HSRP): HSRP is a protocol that provides redundancy for IP networks. It allows two or more routers to share a virtual IP address, which can be used as the default gateway for hosts on the network. If one router fails, the other can take over, ensuring continued network connectivity. The NM-CEM-4TE1 module supports HSRP, providing redundancy for T1 or E1 links.
- Dual Router Configurations: The NM-CEM-4TE1 module can be deployed in dual router configurations, where two routers are connected to each other and share the workload. This provides redundancy in case of a failure of one router, and can help to ensure network uptime.
- Quality of Service (QoS): The NM-CEM-4TE1 module supports QoS, which allows you to prioritize traffic on the network. This can be useful in scenarios where certain types of traffic, such as voice or video, need to be given priority over other types of traffic. QoS can help to ensure that critical applications continue to function even in the event of network congestion.
