The industry's leading tool for certifying twisted-pair cabling and fiber can also verify the delivery of network services over copper. The Network Service Module is an add-on to the DTX cable analyzer that quickly tells a technician if IP-level services and/or Power over Ethernet are available. By coupling service testing with cable certification, the DTX delivers important information that proves an installation conforms to standards and best practices.
Verifying network services
The Network Service Module tests link connectivity, network services and Power over Ethernet to verify network services.
The Network Service Module uses the IP ping function to bounce packets off key network devices including servers and gateways, and then measure the response time. Successful execution of a ping establishes that the link supports communication on the network. Where a DHCP (Dynamic Host Configuration Protocol) server is active on the network, the Network Service Module will obtain its IP address from the DHCP server and then ascertain the IP addresses of other devices on the network.
Network service availability
The Network Service Module measures the utilization of the link under test as a percentage of total available bandwidth. The Network Service Module can blink the activity light of the port to which it is connected to verify proper port connection. The Network Service Module will report the characteristics and capabilities of the hub or switch. In troubleshooting mode this lets a technician quickly determine whether a work area outlet is connected to the desired device and port, and which services are available.
Power over Ethernet (PoE)Product Highlights
A growing number of products rely on Power over Ethernet (PoE) over twisted-pair cable for operating current. Voice over Internet Protocol (VoIP) telephones and 802.11 wireless access points are the two most common. The Network Service Module verifies that the Power Supply Equipment (PSE) is delivering current in compliance with the IEEE 802.3af standard.
- Verify network service availability - determines whether a telecom outlet is active, identifies its data rates up to 1 Gbps, and whether power is available for PoE
- Check link utilization and error conditions - measures the utilization of the link under-test as a percentage of available bandwidth, identifies broadcast traffic and the presence of network error
- Port identification - blinks switch/hub port light, verifies if the link is connected to the proper port or determines where a work area outlet is connected
- Verify link connectivity to the network up to 1 Gigabit Ethernet - uses the DHCP server to get an IP address, pings the default router and DNS server at 10 Mbps, 100 Mbps or 1 Gbps, or you can assign IP addresses manually to ping network devices
- Verify PoE - verifies availability and voltage levels for links connected to power sourcing equipment to supply powered devices for Power over Ethernet applications such as VoIP and wireless access points
- Documents both cabling link certification and network availability and link connectivity test results in a consolidated report using LinkWare
- Troubleshoot link - determines whether performance problems are cabling or network-related
