What is the 660 Series Frame Relay Installation Assistant?
The 660 Series Frame Relay Installation Assistant is a portable, battery-operated, handheld tester used to install frame relay services and perform basic throughput testing and troubleshooting of those services over Wide Area Network (WAN) links.
As an installation tool, the Frame Relay Installation Assistant gives you the option of emulating customer premise or network equipment. This feature enables you to test the function of each network component and determine whether a frame relay service is ready for use before any routers, Channel Service Units/Data Service Units (CSUs/DSUs), or Frame Relay Access Devices (FRADS) are deployed.
As a basic throughput and troubleshooting tool, you can use the tester to verify end-to-end connectivity and test performance of a frame relay network. You can obtain single-ended throughput diagnostics by configuring soft loopbacks in CPE or network switches. Additionally, you can perform end-to-end throughput testing by terminating each end of a permanent virtual circuit (PVC) with a 660 tester and conducting a two-way test.
The tester can also monitor in-service traffic to capture utilization, congestion, and error statistics over a specified period. The data can be stored in the tester's memory or exported to a personal computer for processing by a spreadsheet program or text editor.
The 660 Series Frame Relay Installation Assistant offers two models.
- Model 660T: connects to and tests frame relay service on Dataphone Digital Service (DDS), T1, and Serial circuits.
- Modell
660TE: connects to and tests frame relay service on DDS, T1, E1, and Serial circuits.
Before operating the tester, you must attach it to the appropriate interface module.
Optional interface modules are available for use with the Frame Relay Installation Assistant.
These modules provide the correct jacks and interface circuitry for testing different physical WAN interfaces.
The Frame Relay Installation Assistant offers four interface modules:
- 660M-DDS adapts the tester for connection to DDS transmission circuits.
- 660M-T1 adapts the tester for connection to T1 transmission circuits.
- 660M-E1 adapts the tester for connection to E1 transmission circuits.
- 660M-S adapts the tester to V.35, X.21, RS-449/V.36, RS-232/V.24, and RS-530 serial communication links.
