R2511-HP MSR Router Series Terminal Access Configuration Guide(V5)

93
• The initiator and receiver software of TTY terminal access is developed by HP. The initiator and
receiver use proprietary protocols to exchange packets, supporting good scalability. The TTY
terminal access solution implements the fixed terminal number function and offers many enhanced
functions such as dynamic multi-service switching, real-time screen saving, terminal reset, and data
encryption.
• The initiator of SSH terminal access is developed by HP (an SSH client). The receiver can be a
device developed by other vendors (an SSH server). The initiator and receiver use the standard SSH
protocol to exchange packets. When a client accesses the remote device across an unknown
network, SSH can provide enhanced encryption and authentication functions to ensure security,
protecting the device against attacks such as IP address spoofing and plain text password
interception. HP recommends that you use SSH terminal access if high strength data encryption is
needed.

Configuring receiver parameters
You can specify several receivers with different priority levels on the initiator. The receiver with the highest
priority is the primary receiver, and others are secondary receivers.
