Chapter 1. Overview
1.1 Product Overview
TAINET VENUS Series, a critical part of the Next Generation Network (NGN),
functions as an interface gateway unit between the legacy 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 Series is a Voice-over-IP (VoIP) Gateway that provides cost-effective
and quality voice service over global IP packet network (Internet or Intranets)
for end-users, and, in the meanwhile, lowers 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 Series bridges the PSTN and IP network.
Depending on the installed firmware, VENUS Series supports both Session
Initiation Protocol (SIP) and Media Gateway Control Protocol (MGCP), which
comply with IETF RFC 3261 and RFC 3435 respectively. This document is only
for VENUS Gateways installed with SIP firmware.
VENUS Gateway allows 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 Series, service providers or
telecom companies are able to provision 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 Series installed with SIP firmware provides the following services and
functions:
 Support SIP protocol, which complies with IETF RFC 3261 standard.

Chapter 1 Overview
2
 Venus 2832 Series support up to 32 analog voice interfaces for traditional
POTS (Plain Old Telephone System) equipments (telephone handset,
FAX machines, … etc).
 Modularized analog FXS (Foreign Exchange Station) or FXO (Foreign
Exchange Office) telephony cards provide 8, 16, 24, or 32 telephone
interfaces 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, 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 life-line feature as backup.
 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
 Support RFC-2833 RTP payload for DTMF Digits, Telephony Tones and
Telephony Signals
 Provide Terminal User Interface via the console port、TELNET or web
browser for easy and quick local or remote configuration and monitoring.

Chapter 1 Overview

 Provide SNMP MIB for integrating into service providers’ SNMP
management system.
 Support TFTP protocol for remote software upgrade and configuration file
download.
 User Interface is protected with User ID and Password from unauthorized
users.
 Provide two user accounts with two levels of access privilege.
 Compact 1U-High desktop unit with ear brackets for mounting up to a 19”
shelf.
 Provides a flexible dialing principles, as well as speed dial using hot key,
and hotline direct dial functions.

1.2 Applications
VENUS 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 Series telephone ports
using copper wires (Figure 1-1). With various management features supported
on VENUS 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 Series units at corporate HQ and local branch offices. The
VENUS 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 Series, enterprises can
install proper amount of telephone interfaces for each branch (Figure 1-2).
