Product Overview
The DFCS 4xT1/E1 MUX multiplexes up to four T1/E1 copper circuits and one optional
10/100 Ethernet UTP port onto a fi ber optic link. The aggregated services can be extended
up to 30km across a fi ber pair. The 4xT1/E1 MUX must be used in pairs (bookends)
across dark fi ber.

Installation Procedure
1) Confi gure DIP-switches
2) Install MUX with AC Power
3) Connect Cables
4) Verify Operation
1) Confi gure DIP-switches
DIP-SWITCH BANK 1
SW1 - SW4: Local Loopback Port 1 - Port 4 “Off / LBx”
These DIP-switches control the local loopback function for each T1/E1 port. When
the DIP-switch is in the “LBx” position
(where “x” is the T1/E1 port number), the
corresponding port initiates a loopback
per Figure 3. AIS (all 1s signal) from
the local unit is transmitted across the
fi ber and out the corresponding T1/E1
port on the remote unit. When the DIPswitch is in the “OFF” (default), the port
functions normally.

3) Connect Cables
a. When using the SFP model, insert the SFP Fiber transceiver into the Port 1 SFP
receptacle on the Transport module
NOTE: The release latch of the SFP Fiber transceiver must be in the closed
(up) position before insertion.
b. Connect a Category 5 or better cable to the RJ-48 connectors on the DFCS T1/
E1 MUX, and attach the connectors at the other end of the UTP cable to the
network equipment.
c. When confi gured for E1 coax operation, use the optional adapter cables to con-
vert the RJ-48 interface ports to dual BNC.
d. When using a Transport module with the optional Ethernet port (see Figure 1 on
page 3), connect the Ethernet 10/100 UTP port via a Category 5 or better cable
to an external 10BASE-T or 100BASE-TX Ethernet device.
e. Connect an appropriate multimode or single-mode fi ber cable to the fi ber port of
the Transport module. It is important to ensure that the transmit (TX) is attached
to the receive side of the device at the other end and the receive (RX) is attached
to the transmit side. When using single-fi ber (SF) models, the TX wavelength
must match the RX wavelength at the other end and the RX wavelength must
match the TX wavelength at the other end.
NOTE: Do not remove the modules from the chassis. Access to available
DIP-switches can be found on the side of the chassis.

DIP-SWITCH BANK 2
SW1 - SW4: Port Alarm Relay/LED P1-P4 Alarms “Act / Off”
These DIP-switches enable/disable the port alarm relay and LED function for the
corresponding port. When this DIP-switch is in the “Act” down position (default), the
alarm relay and “Lnk” and “Rmt” LEDs are enabled. When the DIP-switch is in the “Off”
up position, the alarm relay and “Lnk” and “Rmt” LEDs are disabled.
The Port Alarm Relay is a two pin terminal connector located on the front panel of the
4xT1/E1 Multiplexer. It will close when any of the following port alarm conditions are
detected (i.e. alarm relay port 1 will activate when an alarm condition is detected on
port 1).

SW5: Circuit Test (C/T) Mode “Off / On”
When this DIP-switch is in the “Off” down position (default), the Circuit Test Mode is
disabled. When this DIP-switch is in the “On” up position, the Circuit Test Mode is
enabled. When Circuit Test mode is enabled, both MUXes will transmit a known test
pattern. The test pattern is received by the other unit and checked for errors. AIS is
transmitted out all T1/E1 ports and incoming T1/E1 traffi c is discarded. See Figure 4 for
Circuit Test Mode diagram.
Figure 4: Circuit Test Mode
SW6: Local Fiber Loopback “Off / Loc”
When this DIP-switch is in the “Off” down position (default), local fi ber loopback is
disabled. When this DIP-switch is in the “Loc” up position, local fi ber loopback is
enabled on the MUX. AIS is transmitted across the fi ber and out all remote T1/E1
ports. Incoming T1/E1 traffi c at the remote unit is discarded. See Figure 5 for local
fi ber loopback diagram.
Figure 5: Local Fiber Loopback
SW7: Remote Fiber Loopback - “Off / Rmt”
When this DIP-switch is in the “Off” down position (default), remote fi ber loopback is
disabled. When this DIP-switch is in the “Rmt” up position, remote fi ber loopback is
enabled on the MUX. In this mode, the local unit forces the remote MUX into loopback.
AIS is transmitted out all remote T1/E1 ports. Incoming T1/E1 traffi c at the remote unit
is discarded. See Figure 6 for remote fi ber loopback diagram.

Figure 6: Remote Fiber Loopback
SW8: T1/E1 Line Codes - B8ZS/HDB3 or AMI
When this DIP-switch is in the “B8ZS/HDB3” down position (default), the MUX is
confi gured for B8ZS (T1) or HDB3 (E1) line coding. When the DIP-switch is in the “AMI”
up position, the MUX is confi gured for AMI line coding.
2) Install MUX with AC Power
a) AC Powered Chassis Site Preparation
Power source should be available within 5 ft. of the chassis and installed per the
National Electrical Code ANSI/NFPA-70.
This equipment requires a 100-240VAC, 0.5Amp, 50/60Hz power outlet. Appropriate
overloading protection should be provided on the AC power source outlets
utilized.
The standard operating temperature of this equipment is 0 to 50 degrees C.
If installed in a closed or multi-module rack assembly, the operating ambient
temperature of the rack must not exceed the maximum rated 50 degrees C. See
specifi cations on page 13 for wide temperature ranges.
Installation of the equipment should be such that the air fl ow in the front, back and
side vents of the chassis are not compromised or restricted.
Never use this equipment to carry any weight except its own. Never use it as a
shelf to support the weight of other equipment.
b) AC Powered Chassis Mounting
Attach the AC power cord to the back of the Power Receptacle and plug into the
AC outlet. Any installed
DFCS modules will illuminate the power LED.
