Chapter 1: Introduction

When the FMUX04 is ordered with optional Order Wire, a hardware card is installed inside
the unit. The front panel's RJ-11 jack provides a "hot line" between the two FMUX04 units in
the link. Standard telephones may be connected to the RJ-11 jacks and when a phone is taken
"off hook", the remote side will automatically ring. Once answered, both parties may talk
normally. Following the conversation, both parties will place the phones back "on hook" and
the system is again ready for any direct line calls.
Included within the FMUX04 system unit is integrated optical BERT (Bit Error Rate Tester).
This feature provides a built-in pattern generator and receiver. The BERT function is
designed to run "in-band" allowing BER Testing and data transmission to co-exist on the fiber
media. This allows the BERT function to be running constantly even while the unit is in
service, without effecting normal customer data transmissions. The status of the error rate on
the optical connection may then be monitored via LED indicators on the front panel of the
FMUX04.
