AR routers may also be connected to a network via an AUI fanout. This device
has multiple AUI ports wired as transceiver AUIs and a single standard AUI
for connection of a transceiver. This arrangement allows several Ethernet
devices to share a single transceiver. An AUI cable is required if this method is
used.
Transceivers have a switch or a jumper to enable or disable SQE (Signal Quality
Error, also known as heartbeat). AR routers do not require SQE, so it should be
disabled.
AUI cables (sometimes known as drop or transceiver cables) are available from
data cabling suppliers in a variety of lengths up to a maximum of 40 metres,
but are typically between one and five metres in length. AUI cables always
have one female and one male DB15 connector and are fitted with slide lock
retaining clips to ensure a secure attachment.
Voice Ports and Adaptor Cables
Voice ports use a standard RJ11 connector. To connect telephones with a BT-
style connector, use an RJ11-to-BT adaptor cable (Figure 52 on page 89).
