Zhone IMACS-200 ユーザーズマニュアル

6-1

This chapter provides connector pinout, configuration, and troubleshooting information for 
the Foreign Exchange - Station (FXS) Voice port. This port is labeled Voice. See Appendix C 
for pinouts of this connector.

 This port manages the flow of FXS voice traffic over the network. Each port encodes analog 
(voice, VF) signals to a digital bitstream at the local system for transmission over a T1 
network. It also decodes the digital signals to analog at the remote system.

Each of the four FXS ports have two-wire interfaces that support FXS and PLAR. FXS allows 
users to connect the system to a two-way (both inbound and outbound calls) PBX trunk or a 
key system trunk. All the ports are pre-set to use the loop-start function with POTS stations 
and simple PBX trunks. 

The IMACS-200-FXS port has four ports and provides a 600-ohm terminating impedance on 
each port. All FXS features are supported by the IMACS-200.

You must configure the FXS ports for operation. This is done from the FXS Main Screen (see 
Figure 6-1). To go to that screen, highlight the desired port in the System Main Screen and 
press <Enter>. This screen shows one configuration column for each port on the IMACS-200.
