2.4 Coaxial Cable Connection
Connect the unit’s BNC socket to the coaxial cable. When a physical link over coaxial
cable is established and the units are powered up, the VDSL LNK LED will light to
indicate a good connection. See section 2.8 for complete details of LED status.
2.5 Ethernet Cable Connection
The RJ45 port is adaptive and supports auto MDI/MDI-X connection. It can be connected
by straight through or cross-over type Cat5 or Cat 6 cables. The green TP LNK/ACT LED
will light to indicate a connection and flash to show network activity. See section 2.8 for
complete details of LED status.
2.6 DIP Switch Settings
The EE1CL provides four different modes that are user selectable by altering the DIP
switches settings located on the rear panel of the unit. By adjusting the settings the best
transmission mode can be selected to suit the cable quality and distance.
2.6.1 Mode
CO (Central Office) – this is the Master device mode. The unit with this setting is usually
located at the data center of the ISP or enterprise to link to the backbone.
CPE (Customer Premises Equipment) – this is the Slave device mode. The unit with this
setting is usually located at the remote site as the long reach data receiver. The CPE can
be connected to a PC, IP Camera, Wireless Access Point or network devices.
2.6.2 Channel
Fast mode - using this setting guarantees a minimum end to end latency of less than
1ms.
Interleaved mode - using this setting provides impulse noise protection with a duration
of less than 250 µs. Interleaved mode has a maximum end to end latency of 10ms.
2.6.3 Transmission mode
Asymmetric – using this setting means that the upstream and downstream rates are not
the same. When two KBC Extended Ethernet units are connected in a working link the
performance is up to 100/65Mbps for an asymmetric data rate within 200m and up to
25/5Mbps for asymmetric data rate at 3.0km
Symmetric – using this setting means that the upstream and downstream rate is similar.
