Dual fiber optic ports with ST type connectors provide redundant data paths for critical applications. FOT-DF24 802.3 10BASE-FL/FOIRL REDUNDANT TRANSCEIVER WITH LA

The male end of the BNC tee connector is used to connect directly to the host or to the transceiver. The female ends of the tee connector must be connected to another part of the segment or to a terminator. Page 2-1 INSTALLATION Since the ports on the module are internally terminated, the end of the segment that will be connected to the module will not be a tee connector or terminator. 2.2.2 Thin-net Segments (THN-MIM7593 only) The following network design guideline must be followed when connect

About Subscriber IDs Your FRX and SmartSwitch 1800 devices are designed to provide point-to-point dedicated connections among the devices communicating through their serial ports. There are two types of connections used to accomplish this: Permanent Virtual Circuits, or PVCs, which de.ne permanent point-to-point connections which are always available, even when they are not being used; and Switched Virtual Circuits, or SVCs, which are established and broken in response to speci.c call requests.

A more negative setting produces a higher input gain (i.e., 7 produces the least input gain and -22 produces the highest input gain). If the In level is reduced (made more negative), the voice channel will be more sensitive to the input; this will cause the voice output at the remote device to sound louder. The default value for this parameter is 0. Level Out This parameter speci.es the local voice level out of the voice port. A more positive setting produces a higher volume (i.e., 7 produces th
