Overview
1.1 Product Introduction
The TGW1E1-2G, TGW2E1-2G, and TGW4E1-2G (herein referred to as the “TGWxE1-2G”) SIP-ISDN
trunking gateway is one of VoIP gateway product series for Aeonix UC&C. It uses SIP and T1/E1
interfaces for the inter-conversion of IP packets and PCM signals, allowing the interworking of the
IP-based Aeonix UC&C voice network with legacy Public Switched Telephone Network (PSTN), and the
private branch exchange (PBX) of an enterprise.
As a carrier-class VoIP gateway, the TGWxE1-2G is designed according to the requirements of telecom
operators, integrators, value-added service providers as well as large and medium-sized enterprises for
VoIP services. The TGWxE1-2G has distinctive advantages over other similar products in terms of
performance, system reliability, compatibility and cost performance. In addition, the TGWxE1-2G has
efficient software/hardware architecture and powerful DSP processing capabilities, ensuring the
realization of major functions (including the conversion between PCM signals and IP packets, G.711 or
G.729A encoding and decoding of voice signal, echo cancellation, etc.) even under full load conditions.
By supporting ISDN PRI signalling, the TGWxE1-2G can control its calls with the PSTN or PBX. The
call control between the TGWxE1-2G and Aeonix is carried out through Session Initiation Protocol (SIP).
1.2 Features
The TGWxE1-2G has the following characteristics:
High performance
The DSP chip with powerful voice processing used by the TGWxE1-2G is developed by the TI Company.
Its DSP daughterboard ensures a 6000 MIPS processing capability for each TGW gateway, enabling the
TGWxE1-2G to provide functions of voice signal processing (G.711, G.729A, and G.723.1), echo
cancellation, and fax relay (T.38) under full load conditions (120 calls).
High security
The network security of the TGWxE1-2G has been confirmed by NSFOCUS, a proven global leader in
providing enterprise-level network security solutions and services. To ensure better security, the
TGWxE1-2G supports Secure Shell (SSH) and provides functions including automatic password strength
test, password change notification, password anti-crack, ciphertext data storage, external network access
control, blacklist/whitelist, and system log backup.
High reliability and maintainability
To meet the requirements of telecom operators on gateway reliability, the hardware design of the
TGWxE1-2G, from architecture to component selection, takes full consideration of improving the mean
