Figure 97.DAS Fibre Channel – Configuration for Micro-modem Multi-Function Line Drivers
For setting an extended serail line between a Console Concentrator and the S1 port of a
distant node, you can use a pair of micro-modems. A micro-modem ME762A-M or
ME657A-M on the Console Concentrator side and a micro-modem ME762A-F or ME657A-F
on the node side.
Case of the ME762A (Mini-Driver)
The DCE/DTE switch of the micro-modem attached to the Console Concentrator must be
set to the DTE position whereas the switch of the micro-modem attached to the node must
be set to the DCE position.
Case of the ME657A (Multi-Function Line Driver)
An interposer DCE/DTE reference IBM58F2861 must be used to plug the micro-modem on
the Console Concentrator.
