VCL-LD™ T1 DCME Voice Compression equipment provides 24, toll-quality,
very clear and sharp, voice channels using an 6:1 compression
ratio. Also available with fax and data modem support @ 33.6Kbps
data rates. |
This is accomplished
using an advanced, DSP based Viterbi decoder with automatic Voice
/ Silence detection (VAD) and adaptive comfort noise (CNG) generation.
The VCL-LD,
T1 DCME has an in-built T1 Echo Canceller (128ms. echo cancellation
card).
The interface
to the local PSTN Network is ITU-T, G.703, G.704 compliant T1 with
Signaling support for PRI ISDN Signaling, C7 and SS7 Signaling.
VCL-LD
is a natural choice for satellite communications, digital mobile
radio applications, cellular network operators, long distance telephony
service providers (including pre-paid calling card operators), corporate
customers, call-center operators wanting to optimize on expensive
bandwidth usage and offer a competitively priced, toll-quality service
to their customers.
Voice compression technology has been proven to outperform CELP,
RELP, VSELP, MELP, ECELP, MP-MLQ, LPC-10 and other competitive technologies.
Numerous evaluations have shown its ability to provide performance
equal to today's digital cellular systems at under half the data
rate.
The Voice Activation Detection (VAD) algorithm along with the Comfort
Noise Insertion (CNI) performs useful functions in systems trying
to convert periods of silence, that exist in normal conversation,
to savings in system bandwidth. The comfort noise is intend to give
the listener the feeling that the call is still connected as, opposed
to producing absolute silence which can give the impression that
the call has been dropped.
