1. Overview

The IDM MAG-2E1 Digital Trunk Gateway (hereinafter referred to as "MAG-2E1") implements protocol conversion between IMS/SIP and ISDN PRI (30B+D) call signaling through Ethernet ports and E1/T1 interfaces, enabling the connection between next-generation IP voice service networks and enterprise-side traditional Private Branch Exchange (PBX) systems, or connecting next-generation enterprise IP voice switches (IP-PBX) with the traditional PSTN network.

The MAG-2E1 supports 1 to 4 E1/T1 links and 512 SIP trunk account registrations, meeting the VoIP requirements of medium and large enterprises.

With 6000MIPS processing capability, the MAG-2E1 gateway ensures that even under full-load operation of 120 concurrent calls, it can still perform voice processing (G.711/G.729A/G.723.1), echo cancellation, and fax relay (T.38).

Security protection measures supported by the MAG-2E1 include: signaling and media stream encryption, automatic password strength detection, brute-force password attack prevention, encrypted storage of user data, Telnet/SSH function enable/disable, access whitelist, and system log backup.

The MAG-2E1 is equipped with dual Ethernet port redundancy protection to ensure calls are not affected by partial network failures. Additionally, optional 1+1 DC/AC power supply modules are available to meet user requirements for high reliability. In terms of deployment, the MAG-2E1 provides a disaster recovery mechanism for active/standby SIP server registration and switchover. With comprehensive security policies, the MAG-2E1 provides multi-layered, all-around security protection, supporting multiple malicious intrusion prevention mechanisms to effectively address security risks such as brute-force attacks on the management platform and SIP attacks, ensuring worry-free communication and management while meeting the security requirements of enterprises and carriers.
