Raisecom Technology Co., Ltd
When FPT is disabled, it is identical to the AIS function of traditional optical multiplexers. When the
receiving signals of the E1 interface at the remote site are lost, the corresponding local E1 interface will
output all “1” signals; when the receiving signals of the local optical interface are lost, all local E1
interfaces will output all “1” signals.
FPT is designed for users who have special requirements. When FPT is enabled, if there is alarm of
LOS on any direction of optical interface,E1 interfaces on both sides will not output HDB3 code. In this
case, there will be LOS alarm, rather than AIS alarm, on downstream E1 terminal devices (e.g. Switches,
converters or SDH devices).

Thus, both local and remote Ethernet multiplexers can be managed simultaneously, and
the LINK UP port of remote equipment is deactivated. The topology of network
management is described in the figure below.

Note: the PC Agent software can be installed on the network management computer as per
the customer’s requirement.
The management of remote Ethernet multiplexer is performed through the overhead bits of
optical signals. This is called out-of-band network management since it will not take up any
service bandwidth.

5. Installation and test
5.1. Inspect after Opening
Please first check if the models and part numbers are in consistence, and also check if the
equipments are damaged.
5.2. Preparation before Installation
z
z
z
z
z
z
Carefully read this manual
Prepare all kinds of the cable. Ensure that they are not short-circuited. Refer to
Appendix A for cable making.
Ensure the pressure of power supply is in the tolerance range, the chassis is well
connected with the ground.
Prepare the BERT and optical power meter for test of line quality.
Change the dip-switch setting on the bottom panel if 120 Ohm balanced signal
interface is required.
Fix the equipment on to 19-inch rack or place the equipment at stable and secure
environment. Pay attention to the requirements of the ambience.
5.3. Installation
5.3.1. Connecting
z E1 interface
Suggest using SYV 75-2-2 coax adapter; or DB37 interface connected by twisted pair
z Ethernet
Use Cat. 5 or hyper Cat. 5 twisted pair, straight-through or crossover cable.
z Optical interface
Plug SC fiber patch cable into optical interface (push hard until to end). If not sure about
transmission direction, we suggest first turn on the power of device and then plug the fiber.
z Auxiliary data channel
If you want to start the channel, connect RS232 cable at first. Avoid plugging hot swap.
z Network management port
Connect the serial port of computer to LNK-UP port. Configure the dip-switches on the
bottom panel to choose RS232 or RS485 standard. Please note that the remote Ethernet
multiplexer shall be set to “remote management”.
15
Raisecom Technology Co., Ltd
5.3.2. Electrify
If power supply (PS) is DC –48V, first connect middle end to PGND. Turn off PS, connect
“-48V” end with the lower electric level cable, “0V” end with higher electric level cable.
Make sure no reverse connection, or no short circuited, and then turn on power.
If PS is AC 220V, use the PS line in the accessories.
When PS is turned on, the PWR indicator should be on.
5.3.3. Configuring buttons and switches
After turning on power of the device, first ensure there is no alarm on optical port. If optical
ports are connected properly, there shall be no LOS, LOF, and E-3 alarm. The E-6 (yellow)
may be on the moment when the power is just turned on. This is because turning on the
power causes jitters which results in a few bit errors. After 10 seconds, E-6 will be off. This
indicator refreshes in every 10 seconds.
z Test error bit
Use 2M BER Tester to test every E1 error bit level.
z Mask unused E1 alarm
If E1 links are already connected, but there is still are unused E1 tributaries. In this case the
LOS alarm of unused E1 links is called “unused E1 alarm”. Press MASK/NO MASK button
“on” to clear all the unused E1 alarm and all the LOS alarm indicator of E1 tributaries are
“off”.
In the case unused E1 tributary alarm being masked, if disconnection occurs at linked E1
tributary, the LOS indicator of this tributary still will be on.
If power supply is off and back to one again, then the mask function disabled. To enable
mask function need press button to “off” and then pressed it to “on” again.
z Turn on the alarm ring
If after a period of operation, need new E1 tributaries to be connected, need first disable
the mask function and then connect E1 link.

6. Troubleshooting
If you have any problems during installation and using, try to solve them by the following
proposals. If there is no solution, please contact with distributors for technical support.
These following explanations and solutions of alarm for optical port and LOS alarm for E1
tributaries are analyses of local alarm. Please handle it at remote site if there is remote
alarm.
z Green PWR indicator not on
Answer: PS faults. Check if PS working properly and –48 PS connection is not reverse.
z GL is on
Answer: GL is on when alarm happen in local site (L row); GL is flashing when alarm
happen in remote site (R row).
Deal with them as following:
1. Besides GL there are some other alarm indicators red or yellow, please deal with
these alarm at first.
2. Except GL, no alarm happens in L row. But GL is still on in local site (L row). The
reason maybe is that CV alarm exists. It is arose by much longer E1 line or much
disturbance or attenuating more than -6dB.
3. Except GL, no alarm happens in R row. But GL is still on in remote site (R row). The
reason is that HDB3 CV alarm happened in remote site.
z LOS red indicator of optical port is on
Answer: Loss of receiving signal occurs at optical port. Check if the input fiber is connected
well and if there is reverse in connection. Check the received optical power using optical
power meter, it should be greater than receiving sensitivity.
z LOF red indicator of optical port is on
Answer: Loss of frame of receiving signal at optical port. In this case, optical signal has
received, but the optical power may be about critical value of sensitivity. Check RX optical
power to ensure if it connects well at remote optical TX port.
z E-3 red indicator is on at optical port
Answer: The bit error of optical RX signal is greater than 10-3. Check if optical RX port
connects well and RX optical power.
z E-6 yellow indicator of optical port is on
Answer: The bit error of optical RX signal is greater than 10-6. It is normal that there is E-6
alarm just after turning on the power, after about 10 seconds, the E-6 indicator will be off. If
there is E-6 alarm during operation, then check if optical RX port connects well and RX
optical power is normal.
17
Raisecom Technology Co., Ltd
z LOS red indicator of E1 channel is on
Answer: Loss alarm of RX signal at E1 channel, there is no HDB3 signal received. Check if
it connects well at E1 port; if the connection of 75 Ω cable reverse and if the string of 75 Ω
cable in right order. If there is LOS alarm of unused E1 tributary, can press “mask” button to
“on” to make alarm after configuration of device.
