ESCON Channel Attachment

When connected directly to an ESCON channel, the printer can be a maximum distance of 3 kilometers (1.875 miles) from the channel. Either an IBM 9032 or 9033 ESCON Director provides connectivity to additional host systems and also extends the maximum channel length as follows:

The Extended Distance Feature (XDF) on the 9032 or 9033 ESCON Director also extends the maximum channel length as follows:

The IBM 9036 ESCON Remote Channel Extender (Models 1 or 2) extends the interface across common carrier fiber optic connections. You can use one, two, or three 9036 extenders for a maximum distance of 43 kilometers.

Figure 9 shows the details of the above connection options.
