T-BERD®/MTS-4000 Enterprise Services Application Module (ESAM)

Physical Media Tests

All the features of the JDSU Validator line Ethernet speed certifier are included in the

ESAM. Technicians can use the included Plan-Um® software to create cabling layout

diagrams and cable test schedules. After loading the job onto the ESAM, the techni-

cian can run auto-tests for wiremap, length, signal-to-noise ratio, skew, and bit error

rate tests using standard and user-defined cable types. Passing these tests ensures that

the cable can support 1000BASE-T. All of the auto tests can also be performed manu-

ally as can tone generation and ID-only mapping.

Network Connectivity Tests

Once the physical media has been tested and confirmed to support Ethernet, the tech-

nician can test for connectivity to active Ethernet devices on a single drop. If Power

over Ethernet (PoE) is supplied, the pins, voltage, and current can be checked to

ensure it matches the requirements of the powered device. Port discovery will con-

firm that the Ethernet interface is advertising the correct speed and duplex options,

avoiding optional duplex-mismatch issues. The next connectivity test will attempt

to obtain an IP address using Dynamic Host Configuration Protocol (DHCP)

(static configuration is also possible). Duplicate IP addresses will be flagged to the

user’s attention. Once an IP configuration is obtained, the ESAM can perform Ping,

TraceRoute, and Domain Name System (DNS) connectivity tests to ensure connec-

tivity to various network devices. Firewalls can also be tested by Transmission Control

Protocol (TCP)/User Datagram Protocol (UDP) connectivity tests to verify that par-

ticular TCP/UDP ports are open or blocked. If Cisco Discovery Protocol (CDP) and/

or Link Layer Discovery Protocol (LLDP) are used in the network, the analyzer can

read these messages and report them to the user. If issues are observed during many of

the connectivity tests, the technician can chose to view a capture of all frames sent and

received for that specific test allowing in-depth root-cause analysis.
