What is a Trunk Gateway
The
trunk gateway is an important part of the NGN solution. It is located at the
edge access layer of the NGN network and connects the PSTN and NGN networks to
realize the function of IP packet to TDM. It carries the voice tandem task
between the IP domain and the circuit domain, and requires a good processing
mechanism for the echo on the circuit side. The functions of the trunk gateway
include: voice processing, call processing and control, maintenance and
management, etc.
Advantages:
Intelligent access, perfect and reliable
It supports multiple broadband access
solutions such as ADSL and optical fiber, which can achieve flexible bandwidth
expansion and low-cost access. Through routing, NAT, multi-link multiplexing
and detection functions, it can provide enterprises with flexible bandwidth
expansion and low-cost access solutions.
Healthy network, application security
Through its own firewall, anti-virus,
intrusion detection, user access active authentication and other functions, it
provides enterprises with a full range of LAN access security management
solutions. Through its own DHCP server, ARP firewall, DDNS and other functions,
it provides enterprises with a full range of LAN management solutions.
Mobile office, fast and safe
Supports VPN functions such as SSLVPN,
IPSEC, PPTP, L2TP, etc., allowing users to easily and quickly establish a low-cost
WAN private network through one-click operation, providing enterprises with a
secure WAN business transmission channel, and conveniently realizing the
connection between corporate headquarters and mobile staff, branches, partners,
product suppliers, customers, improving the ability to carry out business with
branches, customers, suppliers and partners.
Suppress bandwidth abuse and protect critical services
Dynamic
intelligent bandwidth management function, only one-time setting, automatically
suppresses users who occupy bandwidth, and easily solves bandwidth problems
such as BT, P2P, and video film downloads.
