GDC CELP Voice Channel Modules
Installed on a TMS or OCM, CELP modules
provide compression ratios of up to 13 to 1.
OVERVIEW
OVERVIEW The CELP (Codebook Excited Linear Predictive coding) voice channel
modules bring superior quality voice plus an up to 13:1 compression ratio to
General DataComm’s TMSTM (Transport Management System) and OCM (Office
Communications Manager) products.
Modules can be configured to support compressed voice at channel operating rates
of 9.6, 6.4, or 4.8 Kbps. Users gain the best in
voice quality using high speed digital services while saving on monthly line
costs. In addition, rates can be dynamically downspeeded to accommodate link
restoral rerouting with only a slight adjustment in voice quality.
As an option, the CELP modules can recognize and transmit facsimile signals
uncompressed to remote CELP modules. This automatic bypass feature is
transparent to the user, yielding support for full rate Group III fax at 9.6
Kbps. Module versions are available with or without fax bypass for the
TMS 3000 and the OCM
2000/1000
Office Communications Managers. Flexible signaling choices include 2-wire/4-wire
E&M (Type 1, Type 2, Type 5, and SSDC5A), 2-wire FXS, and 2-wire FXO. DTMF
(Dual Tone Multi-Frequency) signaling is supported by each CELP module. Since
all signaling systems are carried in-band and do not require extra bandwidth,
“hidden” bandwidth costs are eliminated.
