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
