CODEC Packetization
Levels
CODEC synchronization to UGS time clock allows slip-free end-to-end sync to PSTN clock
(minimizes frame slips that can cause Fax/Analog Modem call failures)
Configurable to support AES-128 encryption or no encryption modes
Hearing Impaired Services
Support
TDD support including detection of V.18 including Annex A
Fax and Analog Modem
support
DSP based Modem/Fax Tone detection and support for Voice Band Data Mode with
auto-CODEC negotiation and auto-control of echo canceller, jitter buffer, and voice activated
detection (VAD)
