that they can transmit 10M/100M Ethernet data through multiple E1 channels
in point to point condition. It is different from normal bridge, supporting
1E1/2E1/4E1/8E1 customized configured channels, auto detecting the
number of E1 channels and uses the available working E1, allow some limiting
transfer delay between different E1 channels. 1 channel can go up to
1984Kbits/s, 2 channels can go up to 3968Kbits/s, 4 channels can up to
7936Kbits/s and 8 channels can up to 15872Kbits/s. It can connect with
Ethernet switch or hub when in 10/100Mbps full/half duplex mode; make use
of mass E1 resources in telecommunication networks to expend the transfer
distance and application of Ethernet. It is a suitable solution for broadband and
Multiplay connectivity. It can used in areas such as connecting LANs,
connecting end offices, Video on demand, remote monitoring, E1 interface of
switches, etc.

6 Installation of SNMP Management Software
6.1 Hardware Installation
The SNMP card must be properly installed in the SNMP indicative slot.
After installing SNMP card in to rack, Power On the rack then LED’s will
blink and then OFF except PWR.
Connect LAN port of SNMP card to PC with cross cable or to SWITCH with
straight cable.
6.2 Software Installation
6.2.1 Change Default IP Address through WEB
There is a simple web server in the equipment, which provides a way to
change the IP address from network. You can connect the RJ-45 port on your
PC with the NM port on the desktop equipment or the Ethernet port of SNMP
card on the rack equipment through Ethernet crossover/straight through cable
(Default IP Address: 192.168.10.10, Subnet Mask: 25 5.255.255.000). Now
change your PC IP in to the same range that means 192.168.10.XXX, after
that you can open the Internet Explorer on your PC and you get below screen
in which password need to be entered:
Installation and Operation Manual
©2007 PRECISION ELECTRONICS LTD. 27
At this time, you should input the password (PEL or admin or hctel) and then
you can see the figure show below:

6.2.2 Installation of SNMP Management Software
You can install the SNMP management software on your PC. After you
finished this, you can configure the parameters of the equipments by this
Software. Now you can configure the remote end equipment by connecting
your PC with the local equipment’s NM port and the network management
system on your PC in the scenario of point to point network, and you can
monitor the status of the remote equipment too. Remember: SNMP Software
does this job through SNMP on the point-to-point network. PC along with
Windows OS and IE browser is required. Do the following step:
o Install the windows SNMP protocol
o Install SNMP management software
6.2.2.1 Install the SNMP protocol in PC
Double click “My Computer” on your computer.
Double click “Control panel”.
Double click “Add/Remove programs”.
Single click “Add/Remove Windows Components” button on the left of this
window.
Select “management and monitoring tools”, and then confirm it to install
SNMP protocol.
NOTE: After the above five steps, the computer will install the SNMP protocol
automatically. During the process, you will be asked to insert the “Windows
Operation System CD”. So you should prepare your operation system CD to
finish the task.

Note:
FAL Alarm:-
Device will detect one special bit when it receive the signal, and compare
with the special bit in the signal which it send out, if they are continuously
different 3 times, device will give FAL alarm. Please refer below conditions:
If you don't connect the E1 line, there are 3 condi tions:
A. You don't set any loop back, FAL bright, because device does not receive any signal.
B. You set remote loop back, FAL bright, then no matter you connect the E1 or not, the FAL will keep bright the same.
C. You set local loop back, FAL off, because the device receive signal which from it.
If you connect the E1 line, there are 3 conditions:
A. You don't set any loop back, FAL off. Then if the E1 error rate on the line go to bad to one level, that the signal which device receiving is not as per the requirement, so FAL will be bright.
B. FAL off, then you set remote loop back, FAL off as the same, because all the data and clock will loop back to remote device, device will not detect any changes on clock, so FAL will keep off the same.
C. FAL off, then you set local loop back, FAL off as the same, because device receive signal which from itself, FAL will keep off the same.
Loop Back:
You can set 4 types loop back through software, they are A, B, E, and F.
A is local loop back at local device
B is remote loop back at local device
E is remote loop back at remote device
F is local loop back at remote device
A B C D E F
