DSP Image for the PVDM3
The DSP image for the PVDM3 supports all features supported on PVDM2 except Cisco Fax Relay. The
DSP image provides feature capability to implement the signal processing layer for a TDM-to-IP
gateway:
• TDM-to-IP gateway for voice telephony, including support for multicast conferencing through the
mixing of multiple IP streams out a single TDM port.
• Low-level processing of CAS from a T1/E1 interface through the use of digital signaling channels.
• Control and low-level processing of the signaling for analog telephony interface implemented on
Cisco’s voice interface card (VIC) hardware.
• Support for Voice Band Data (VBD) through the use of upspeeding channels.
• Support of facsimile using T.38 Fax Relay technology.
• Support of high-speed modems (V.32 and V.34) using Modem Relay technology.
• Interface with Secure Telephony (STU) phones using Secure Telephony over IP standard
technology.
• Support for interfacing VoIP channel to Land Mobile Radio (LMR) networks.
• Support for secure VoIP through the implementation of SRTP for both encryption and authentication
of RTP packets.
• Support for text telephony (Baudot) using Text Relay technology.
The DSP image for the PVDM3 also provides a complete set of features to implement the signal
processing layer of an IP-to-IP gateway and an IP-based conference server. Highlights of this
functionality include:
• G.711 transcoding for implementing a LAN-WAN gateway.
• Universal Transcoding between any two voice codecs (narrowband or wideband).
• Trans-scripting services for conversion between SRTP configurations or between secured and
unsecured networks.
• IP-based voice conferencing, including narrowband and wideband participants.
