Description

If you’ve been waiting for the perfect digital test set, then wait

no longer! The Wilcom D400 Digital Test System ushers in a

new era in transmission testing. By providing a complete set of

T1 Test functions today while looking ahead to your testing

needs of tomorrow the D400 removes one major drawback

found in other test sets — obsolescence.

Rest easy knowing you can purchase only those test functions

that are required immediately. Then as your testing needs grow,

simply purchase the option cards and software packages that

meet your new demands. Installation is easy, performed by you

or through our factory. To make installation of option software

as simple as possible, the D400 includes Flash PROMS. Using

Flash PROMS allows downloading of new system software by

dial-up modem connection. Therefore, physically changing

the PROMS is no longer a concern. In a world of ever changing

technology, the D400 is definitely a safe investment.

The D400 Digital Test System is designed with expansion in

mind. Its rugged chassis can accommodate a wide selection of

option cards (e.g. BERT testing, DS3 Drop & Insert, DTMF/

MF signaling, DDS & Factional T1, FDL Access, SLC-96

Derived Data Link access) and two processor enhancements

(e.g. memory expansion, internal dial-up modem). Back panel

connection plates provide the capability to add any type of

future connector — including 75 Ω coaxial, RS-232C, and

fiber optic. The 75 watt power supply has enough muscle to

support all currently available and future option cards, and the

Intel 80188-based processor has memory and capacity to spare.

The D400 Digital Test System is available in two versions: a

bench test set version, the D400 with five expansion slots and

a field test set version, the D450 with two expansion slots. Both

base units are complete in-service T1 test sets. Their full-

duplex drop and insert capabilities allow simultaneous channel

testing in both directions. The two channel tone synthesizers

and receivers provide noise and frequency measurements from

0 to 3990 Hz. Bit patterns can be sent and displayed in both

directions simultaneously. The A/B/C/D signaling bits of all 24

channels can be scanned and displayed on screen. Loop timing

and frame slip counting is performed. Plus all the performance

monitoring features are included so tariffed service require-

ments can be checked and verified. This makes the D400 and

D450 base units complete DS1 test sets unto themselves.

Several optional accessories are available, including the D555

Non-Intrusive Probe used for testing T1 anywhere on twisted

pair, a thermal printer, and a padded carrying case. Shipped with

every unit is a comprehensive manual and the D400 EZ Test

Index, a quick step-by-step guide to test setup.
