Chapter 2 Planning Your Installation

Distance Limitations for Interface Cables

Before you connect a device to the synchronous serial port (labeled SERIAL 0), you need to know the following:

Type of device, DTE or DCE, you are connecting to the synchronous serial interface

Type of connector, male or female, required to connect at the device

Signaling standard required by the device

Distance Limitations for Interface Cables

When planning your installation, consider distance limitations and potential electromagnetic interference (EMI) as defined by the Electronic Industries Association (EIA). Distance limitation information is included for the following IAD ports:

Fast Ethernet Maximum Distance, page 2-4

T1/E1-WAN Port Maximum Distances, page 2-4

Serial Port Maximum Distances (WIC/VIC Cards), page 2-4

T1/E1-PBX Digital Voice Port Maximum Distances, page 2-6

FXS Analog Voice Port Maximum Distance, page 2-6

FXO Analog Voice Port Maximum Distance, page 2-6

Fast Ethernet Maximum Distance

The maximum segment distance for Fast Ethernet is 330 feet (100 meters) (specified in IEEE 802.3).

T1/E1-WAN Port Maximum Distances

Table 2-1shows the distance limitations for T1/E1 signals (specified in ANSI T1.403).

IAD2430 specifications

Cisco Systems IAD2430 is a versatile Integrated Access Device (IAD) designed to deliver voice and data services to small and medium-sized businesses. This device plays a pivotal role in the convergence of voice and data networks, offering a comprehensive solution that simplifies management and enhances operational efficiency.

One of the most compelling features of the IAD2430 is its support for both traditional TDM (Time-Division Multiplexing) and VoIP (Voice over Internet Protocol) technologies. This dual capability enables businesses to migrate to IP-based voice solutions while still maintaining their existing TDM infrastructure. The IAD2430 is equipped with multiple built-in voice ports, allowing it to support a variety of telephony applications.

In terms of performance, the IAD2430 offers robust Quality of Service (QoS) features that prioritize voice traffic to maintain call clarity and reliability. This is particularly critical in environments where voice communication is essential for daily operations. QoS mechanisms ensure that voice packets are transmitted with minimal latency, jitter, and packet loss, providing an uninterrupted communication experience.

The IAD2430 also boasts advanced security features, including firewall protection and encrypted data transmission. This is particularly important for businesses looking to protect sensitive information and ensure compliance with industry regulations. The built-in security measures help safeguard against unauthorized access and potential threats, providing peace of mind to users.

Moreover, the device supports various WAN connections, including T1, DSL, and Ethernet, making it adaptable to different network environments. Its flexible connectivity options allow for seamless integration with existing network infrastructure while maximizing bandwidth utilization.

Management and configuration of the IAD2430 are simplified through a user-friendly web interface and support for remote administration. This allows IT staff to efficiently configure and monitor the device without the need for onsite visits, thus reducing operational costs.

In summary, the Cisco Systems IAD2430 stands out as a reliable and feature-rich IAD capable of catering to the needs of businesses that require integrated voice and data services. Its combination of TDM and VoIP support, enhanced QoS, robust security features, and flexible connectivity options make it an ideal choice for organizations looking to streamline their communication solutions.
