Feature
Benefits
Standards-Based Compression Algorithm
Support
Users can choose to either transmit voice across their networks as uncompressed PCM
(G.711, u-law and A-law) or compressed from 5.3 kbps to 32 kbps using standards-based
compression algorithms (G.729, G.729a/b, G.723.1, G.726, G.728).
Fax Support
Transmit Group III fax over any voice channel without sacrificing voice processing
resources regardless of compression type.
Voice Over IP
Transmit data, voice, and video across a single frame relay, ATM, ISDN, channelized, or
multilink point-to-point protocol (MLPPP) network.
Voice Over Frame Relay
Leverage existing or new frame relay network by transporting voice directly over this
network using standards based transport methods (FRF.11) combined with standards based
fragmentation for data (FRF.12). VoIP can also be transmitted over Frame Relay.
Voice Over ATM
Transport voice directly over ATM networks using AAL2 and AAL 5 encapsulation.
Leverages existing ATM networks as a direct transport method for voice. VoIP can also be
transported over ATM (VoATM requires ATM network modules such as IMA or OC-3).
Connection Trunk
Creates a tie-line replacement structure while only consuming bandwidth during a call
(digital-to-digital, digital-to-analog, or analog-to-analog capabilities).
Toll Bypass
Reduce or eliminate toll charges assessed by long distance and local carriers by transporting
voice and fax traffic across the enterprise intranet, LAN, metropolitan-area network (MAN),
or WAN.
Integrated Data WAN Support
Connect one or two T1 or E1 interfaces on this network module as a WAN interface either
as one or multiple groups of DS0’s or as an entire T1 or E1 frame while still providing
packet voice support for connections to PBXs and the PSTN.
LVBO (Local Voice Busy-Out)
Automatically busy out any desired voice trunk line (or individual DS0s) to a PBX or PSTN
when a direct WAN or LAN connection to the router is down. Also, busy out a far end trunk
connection when configured for Connection Trunk.
Call Admission Control Using RTR
Uses Response Time Reporter (RTR) to determine latency, delay and jitter and provide real-
time ICPIF calculations before establishing a call across an IP infrastructure. RTR packets
emulate voice packets receiving the same priority as voice throughout the entire network. A
superior method to data and ping packets for determining congestion levels.
Off-Premise Extension (OPX)
Extends the capability of legacy PBX to off-premise phones.
Voice Activity Detection (VAD)
Consume bandwidth during a call only when there is voice traffic to send (silence
suppression)
Comfort Noise Generation
While using VAD, the DSP at the destination emulates background noise from the source
side, preventing the perception that a call is disconnected.
