MAKING NETWORK CONNECTIONS

•Delay - Must not exceed 1000 nsec for a 10BASE-T link. This delay limits maximum link segments to 200 meters.

•Crosstalk - Crosstalk is caused by signal coupling between cable pairs within a multi-pair cable bundle. Crosstalk should not be a problem if the cable meets all other requirements.

•Noise - Noise can be caused by either crosstalk or externally induced impulses. Impulse noise may cause data errors if the impulses occur at very specific times during data transmission. If noise related data errors are suspected, it may be necessary to reroute the cable or eliminate the source of the impulse.

•Temperature - Multi-pair, PVC 24 AWG telephone cables have an attenuation of approximately 8 to 10 dB/100 m at 20°C. The

attenuation of PVC insulated cable varies significantly with temperature. At temperatures greater than 40°C, we strongly recommend that you use plenum rated cables to ensure that cable attenuation remains within specification.

3.2 CONNECTING TO A THIN-NET SEGMENT

To connect a thin coaxial 10BASE-2 segment to an adapter with a BNC port, attach a BNC tee-connector (2, Figure 3-3) to the adapter’s BNC port (1, Figure 3-3). Next, attach the thin-net segment (3, Figure 3-3) to one of the male connectors on the tee- connector.

Each segment attached to the tee-connector must be terminated. If a segment is not attached to one of the male connections on the tee-connector, then a terminator (5, Figure 3-3, View A) must be placed on that connection. Attach another thin-net segment (4, Figure 3-3, View B) or a terminator (5, View A) to the other male connector on the tee-connector.
