INSTALLATION AND OPERATION MANUAL
RL1000GW
TECH SUPPORT: 1.888.678.9427
This mode allows higher availability for the end to end connection and traffic validation.
TCP connection mode will use by default, frame mode for the service ‘buffer-mode’. That is unless
‘buffer-mode’ was explicitly set to ‘byte’ by the user.
Service Port number
the TCP/UDP port number used at a serial tunneling connection is defined by the values of
‘service-id’ and the ‘low-border-ip-port’ set at the ‘serial’ ‘settings’.
Reference drawing
For ease of explanation of following terms and serial properties at this chapter, below diagram will
be used as a reference to follow on the serial traffic flow.
The diagram demonstrates two RL1000GW routers connected over an Ethernet network and
sharing a transparent serial tunneling service.
The customer equipment #1 (CE1) is a serial master sending data to a serial slave CE2. For
simplicity purposes, the diagram and explanations refer to unidirectional traffic from CE1 to CE2.
