Chapter 1. Overview
1.1 Product Overview
TAINET VENUS 29xx Series, a critical part of the Next Generation Network (NGN),
functions as an interface gateway unit between the traditional Public Switched
Telephone Network (PSTN) and the IP packet network by performing the
conversion of the analog voice traffic to/from the IP-based media stream.
VENUS 29xx Series is a Voice-over-IP (VoIP) Gateway that provides cost-effective
and quality voice service over global IP packet network (Internet or Intranet) for
end-users, and, in the meanwhile, lower the installation and maintenance effort.
With analog voice interface connecting to user‟s existing telephone handset or
PABX, and the Ethernet interface connecting to the service providers' IP network,
VENUS 29xx Series bridges the PSTN and IP network.
Depending on the installed firmware, VENUS 29xx Series supports Session
Initiation Protocol (SIP), Media Gateway Control Protocol (MGCP) and MEGACO
which comply with IETF RFC 3261, RFC 3435 and RFC 3525 respectively. This
document is only for VENUS 29xx Series installed with SIP firmware.
VENUS 29xx Series allow traditional PSTN users to make phone calls over the
Internet without changing their telephone operating procedure. Using a Proxy
Server or SoftSwitch together with the VENUS 29xx Series, service providers or
telecom companies are able to provide integrated voice and data service over the
IP network to their customers. Features like billing, accounting and network
management supported by the SoftSwitch are available as well.
VENUS 29xx Series installed with SIP firmware provides the following services
and functions:
Support SIP protocol, which complies with IETF RFC 3261 standard.

Chapter 1 Overview

Venus 2908/2916/2924/2932 Series support up to 8/16/24/32 analog voice
interfaces respectively for traditional POTS (Plain Old Telephone System)
equipments (telephone handset, FAX machines, etc).
Venus 2908 Series provides 4 FXS/4 FXO ports or 8 FXS, Venus
2916/2924/2932 Series provides 16/24/32 FXS telephone interfaces and
Venus 2932 FXO provides 32 FXO interfaces respectively for various
customers. Each telephone interface can drive at least three telephone
handsets through up to 4 km (13k feet) of 24 AWG copper lines.
Support ITU-T standard voice codecs.
Apply quality VoIP technologies including: Real-time voice packet
encapsulation and voice play-out based on the Real-Time Protocol (RTP),
Adaptive Jitter Buffer, Echo Cancellation（ITU-T G.168/165）, Compensation
for Loss of Packet, Voice Activity Detection (VAD) and Silence Suppression.
Support T.30 Transparent FAX service or T.38 FAX Relay.
Supplemental Class 5 features like Call Forwarding, Caller ID
Display/Blocking, Call Returning, Speed Dial, Call Waiting, Call Transfer,
Voice Message Indication, Hotline, Call Park and 3-way Conferencing… etc
can be easily supported.
Use static IP address assignment or obtain the dynamic IP address from a
DHCP (Dynamic Host Configuration Protocol) Server or BootP (Bootstrap
Protocol) Server.
Provide DHCP server function on LAN port.
Provide PSTN lifeline feature as backup. (2908 only)
Support PPPoE function (Point-to-Point Protocol over Ethernet), NAT/NAPT
function (Network Address Translation/Network Address Port Translation),
port-based VLAN, VLAN ID and priority tagging, and QoS function that
including IEEE 802.1p and IEEE 802.1Q

1.2 Applications
VENUS 29xx Series, designed as a desktop or rack-mount unit, can be easily
installed in a telecommunication equipment room of a building. It uses the standard
10/100 Base-T Ethernet to connect to the service providers' IP backbone through
the router or data communication equipment. Up to 32 traditional telephone
handsets or FAX machines located in the rooms at each floor of the building can
be connected to the VENUS 29xx Series telephone ports using copper wires
(Figure 1-1). With various management features supported on VENUS 29xx Series,
service providers or telecomm companies can provide toll-quality voice service to
the customers. The deployment of an intelligent IP packet network for integrated
data and voice service with billing, accounting, and management features can be
soon built up.
Figure 1-1 Typical SIP VoIP Application
Large or median sized enterprises are able to build-up the high quality, cheap or
free, private voice service based on the Intranet or Extranet network by deploying
VENUS 29xx Series units at corporate HQ and local branch offices. The VENUS
29xx Series communicates with the SoftSwitch/SIP Proxy Server installed at
corporate HQ through managed IP leased line, such as DDN (Digital Data Network)
leased line or VPN (Virtual Private Network) network. With the scalable voice
capacity feature provided by VENUS 29xx Series, enterprises can install proper
amount of telephone interfaces for each branch (Figure 1-2).
