Overview
1.1 Product Introduction
The TGWxE1 Trunking Gateway (hereinafter referred to as the TGWxE1) is one of VoIP product series
developed by
Tadiran Telecom.
It uses the SIP and T1/E1 interfaces for the inter-conversion of IP packets
and PCM signals, allowing the interworking of the IP-based new-generation voice network to legacy
Public Switched Telephone Network (PSTN), and the private branch exchange (PBX) of an enterprise.
As a carrier-class VoIP gateway, the TGWXE1 is designed under the requirements of telecom operators,
integrators, value-added service providers as well as large and medium-sized enterprises for VoIP
services. The TGWXE1 has distinctive advantages over other similar products in terms of performance,
system reliability, compatibility and cost performance. In addition, the TGWXE1 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, and echo cancellation, etc.) even under full load conditions.
By supporting the ISDN PRI signalling, the TGWXE1 can control its calls with the PSTN or PBX. The
call control between the TGWXE1 and media gateway controller (softswitch) is carried out through
Session Initiation Protocol (SIP). By now, the TGWXE1 has successfully passed the interoperability test
with various popular softswitch platforms and IP PBX products.
1.2 Features
The TGWXE1 has the following characteristics:
High performance
The DSP chip with powerful voice processing used by the TGWXE1 is developed by the TI Company. Its
DSP daughter card ensures a 6000 MIPS processing capability for each gateway, enabling the TGWXE1
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 has been confirmed by NSFOCUS, a proven global leader in
providing enterprise-level network security solutions and services. To ensure a better security, the
TGWXE1 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 the gateway reliability, the hardware design of the
