3To configure the parameters of a specific trunk, from the trunks displayed on the top, select the trunk you want to configure by clicking the Trunks Status indicator. The first parameter named Trunk ID changes according to the trunk you click. The parameters displayed are for the selected trunk only.

4To modify the selected trunks parameters, click Stop Trunk; the trunk is stopped and the Trunk Configuration State parameter changes to Inactive. The parameters are no longer grayed and can be modified. The Apply Trunk Settings button appears at the bottom of the screen. When all trunks are stopped, the Apply to all Trunks button also appears at the bottom of the screen.

If the trunk cant be stopped because it provides the gateways clock (assuming the V7122 gateway is synchronized with the E1/T1 clock), assign a different E1/T1 trunk to provide the gateways clock or enable TDM Bus PSTN Auto Clock on the TDM Bus Settings screen.

To assign a different E1/T1 trunk that provides the gateways clock, access the TDM Bus Setting screen and change the TDM Bus Local Reference number to any other trunk number (this operation can be performed on-the-fly).

5From the Protocol Type drop-down list, select the required protocol. Note that different trunks can be defined with different protocols (CAS or ISDN variants) on the same gateway (subject to the constraints in the V7122 gateway Release Notes).

When modifying the Protocol Type field, the menu is automatically updated according to the selected protocol (ISDN, CAS or Transparent). Additional parameters are appropriate to the selected protocol type.

6From the Framing Method drop-down list, select the required Framing Method (for E1 trunks, always set the Framing Method to Extended Super Frame).

V7122 specifications

The 3Com V7122 is a robust and versatile Layer 2/3 switch designed for small to medium-sized enterprises seeking a reliable networking solution. It plays a crucial role in improving network performance and enhancing connectivity for a growing number of devices in today’s digital landscape.

One of the standout features of the V7122 is its advanced switching capabilities. It supports 24 Ethernet ports, providing ample connectivity options for various end devices like computers, printers, and cameras. The switch offers a combination of copper and fiber interfaces, ensuring flexibility in deployment, whether for short-range or long-range connectivity.

The V7122 is equipped with a sophisticated traffic management system, which includes Quality of Service (QoS) features. This allows organizations to prioritize network traffic according to application requirements, ensuring bandwidth is allocated effectively. With this capability, time-sensitive applications such as voice-over-IP (VoIP) and video conferencing can function smoothly without interruption.

Another significant technology incorporated into the 3Com V7122 is its compatibility with VLAN (Virtual Local Area Network) configurations. This feature enables the segmentation of a network into multiple virtual networks, enhancing security and reducing congestion by limiting broadcast traffic. The ability to create subnets helps organizations to better manage their network resources and maintain optimal performance.

Moreover, the V7122 supports various network protocols, facilitating seamless integration within existing IT infrastructures. Its stackable design allows for easy scaling, enabling businesses to expand their network as needed without a complete overhaul. The switch also boasts an intuitive user interface, which simplifies management and configuration processes, making it accessible to network administrators of varying skill levels.

The 3Com V7122 stands out for its reliability and durability as well. It is built to handle the demands of an enterprise environment, featuring a compact and robust chassis designed for continuous operation. With the ability to support power over Ethernet (PoE), the switch can power connected devices directly through the Ethernet cable, eliminating the need for separate power supplies and reducing cable clutter.

In conclusion, the 3Com V7122 is a powerful networking solution that combines advanced switching features, traffic management capabilities, and flexible configurations. Its compatibility with various technologies and protocols makes it an ideal choice for organizations looking to optimize their network infrastructure for current and future demands.
