THE VE790 SERIES PROVIDES A TOTAL LINE CARD SOLUTION THAT

GIVES CUSTOMERS TOTAL FLEXIBILITY IN DESIGNS RANGING FROM

INTERNAL OR EXTERNAL RINGING TO CALL CONTROL AGGREGA-

TION AND INTEGRATED LINE TESTING.

The VE790 VoiceEdge™ VE790 Series is a high-performance, highly programma-

ble integrated voice chip set that performs all the functions necessary to create a

2-wire, twisted-pair telephone interface from any broadband digital source. The

VE790 Series includes 2-, 4-, and 8-channel programmable codecs along with

short, medium and long loop length SLIC devices that together operate with

minimal external components and include software to provide a complete sys-

tem solution.

Programmability and integrated line testing when used with the optional Le79112

VCP I or Le79114 VCP II device, make the Ve790 Series the most flexible chip set

available.

Features

Complete system solution: SLAC

device, SLIC device, LCAS device,

VCP, integrated test firmware, and

regional coefficient generation

Supports comprehensive "Carrier

Class" self and loop testability

Control aggregation with the VCP

Enables high system Integration and

implementation density

Available support tools

Standards: compliant with all

relevant ANSI and ETSI standards,

including GR- 822, GR-909, and

GR-844 line measurement

requirements

Benefits

Complete BORSCHT functionality in

one chip set

Provide early detection of existing or

future telephone line or equipment

failures and line performance

characteristics

Eliminates unnecessary truck rolls

Carrier class line testing for remote

applications

Off-loads real time control

and management from the

microprocessor for up to 32 channels

allowing the use of a lower cost/

power host processor

Integrated ringing and test

eliminates need for external relays

Self diagnostics & system testing

lower cost
