SmartxDSL
xDSL converts existing twisted-pair telephone lines into access paths for multimedia and
high speed data communications. There are a number of different types of DSL
technologies, all of which are suited for testing by SmartxDSL.
The following cards can be tested using a SmartBits 200/2000 chassis:
•
AT-9025, ATM, 25 Mbps.
•
AT-9045B, ATM, DS3.
•
AT-9155C, ATM, Fiber, OC-3, Multi Mode.
•
AT-9155Cs, ATM, Fiber, OC-3, Single Mode.
•
AT-9622, ATM, Fiber, OC-12, Multi Mode.
•
AT-9622s, ATM, Fiber, OC-12, Single Mode.
•
AT-6710, 10 Base-TX, Layer 3.
•
LAN-3111A, 100 Base-FX Fiber.
•
ML-7710, 10/100 Base-TX, SmartMetrics.
•
ML-5710A, 10 Base Ethernet, USB, SmartMetrics.
Refer to the SmartxDSL API Manual located at http://www.netcomsystems.com/support/
documentation.asp for a complete description of the tests available. Table 6-5 gives a brief
description of these tests.
Multicast Group Capacity Measures the maximum number of multicast groups
and group members that the DUT can handle.
Scaled Group Forwarding
Matrix Determines the following:
•
The DUT’s multicast forwarding rate for a fixed
port configuration.
•
The DUT’s forwarding performance as the number
of multicast groups and source IP addresses
increase.
