Benefits

Variable, long bridged tap simulation

The DLS 8110 simulates the TP1 (26 AWG) bridged tap that is variable from 0 to

250 feet in 10 foot increments. Long bridged taps are important in VDSL data rate

and BER (Bit Error Rate) performance testing. Increments as short as 10 feet allow

the testing to be very focused in identifying access device problems.

Flexible bridged tap(s) set-up

A basic VDSL loop simulation system includes a DLS 8100 chassis (or at least one

DLS 8111 chassis) and at least one DLS 8110 chassis. A DLS 8100 (or DLS 8111) +

a DLS 8110 system offers VDSL testloops with long variable bridged tap(s) in

smaller increments. This helps to provide complex loops beyond the current VDSL

standard T1E1.4/2001-009R2 and ITU-T G.993.1 (previously known as G.vdsl).

Continuous bandwidth

The DLS 8110 and DLS 8111 combination provides continuous bandwidth from DC

to 30 MHz that is essential for the testing of VDSL co-existing with voice and

ISDN application on the same twisted pair.

Low noise floor

Passive component design approach allows attenuation, input impedance and

propagation delay of twisted pairs to be properly simulated while providing a low

noise floor.

Multiple control interfaces

IEEE or RS-232 interfaces allow for integration into a customer's test environment

and fully automated control.

Remote control

The DLS 8110 is configured for North American VDSL (as well as other xDSL)

standards. All VDSL wireline, VDSL bridged tap, and noise impairment test cases

are easily selected via the DLS 1100 GUI or integrated into an automated testing

system via SCPI (Standard Commands for Programmable Interfaces) or Spirent

Communications' ScriptCenter.

Spirent DLS 8110 VDSL Bridged Tap Simulator

DLS 8110

Growing demand for high bandwidth multimedia

applications with integrated voice, data and video is

one of the primary drivers for VDSL technology, the

natural evolution from ADSL. To assist data rate

performance testing in VDSL chipset and modem

development, which are sensitive to bridged taps,

Spirent Communication has launched the DLS 8110

VDSL Bridged Tap Simulator. Used with the DLS 8100

(or the DLS 8111) VDSL Wireline Simulator, the

DLS 8110 helps to provide VDSL test loops that

include variable bridged taps with small increments.
