4. This is the cable between the MII port on the FEIP port adapter and the appropriate transceiver.
5. This refers specifically to any two stations on a repeated segment.
Table 2-3 summarizes the characteristics of 100BaseT with respect to IEEE 802.3u physical
characteristics.

Channel Attachment Connections
Referring to the CIP, the maximum transmission distance for ESCON (with LED) is 1.9 miles
(3.1 km) point-to-point or 5.7 miles (9.2 km) with two ESCON Directors. The maximum
transmission distance for bus and tag is 400 feet (122 m). The IBM 3044 C/D (host side/remote side)
copper-to-fiber repeater can be used to extend the bus and tag distance up to 1.2 miles (2 km).
E1-G.703/G.704 Connections
Unbalanced G.703 interfaces allow for a longer maximum cable length than those specified for
balanced circuits. Table 2-4 lists the maximum cable lengths for each FSIP E1-G.703/G.704 cable
type by the connector used at the network (non-FSIP) end.
