Chapter 1 Introduction WinLink 1000 Installation and Operation Manual
TDM Interface
The WinLink 1000 TDM interface accepts E1 or T1 traffic, supporting
the following:
• Unframed operation (E1 and T1)
• AMI and B8ZS zero suppression (T1).
Advanced Encryption System
WinLink 1000 (version 1.500 and above) ensures user's data security
with one of the most sophisticated commercially available combined
encryption and authentication techniques, CCM/AES. This technique
combines message authentication (preventing antispoofing and replay
protection) with commercial encryption, and complies with the IEEE
802.11i (phase iii) security recommendations.
CCM/AES uses a symmetric 128-bit encryption key (EK), and a nonce,
and provides both message encryption and authenticating signature.
The nonce mechanism enables the receiver to remember already
received genuine messages and reject all replayed messages.
Initial encryption and authentication is based on a user-defined master
key (Link Password). While standard Wireless LAN encrypts only the
Ethernet Payload, WinLink 1000 encrypts both the source and
destination MAC addresses.
Management
WinLink 1000 has full local and remote management capabilities. The
user-friendly SNMP-based management tool provides full end-to-end
configuration, event log and performance monitoring capabilities.
Alternatively each site can be configured or monitored via a Telnet
terminal.
Diagnostics and Performance Monitoring
WinLink 1000 supports activating local and remote loopbacks on E1/T1
links.
WinLink 1000 constantly monitors the data transmission process,
evaluates received signal strength, and signal quality. It also monitors
received traffic and frame rate (FPS) for local and remote units.
