2 Introduction
OPCOM3100 is an SDH access device which supports both Ethernet services and E1
services, and is developed as an edge access device for the purpose of full use of the
resource of SDH networks. OPCOM3100 can aggregate the user data flows and
multiplex them to STM-1 data. You can access OPCOM310 0 via the device’s serial port
RS232 or network management interface: Telnet and it also provides standard SNMP
management interface and can be field upgraded.

4.2 Managing configuration files and startup files
4.2.1 Configuration files
¾ The present reserved configuration file name is startup_config.conf by default.
¾ Use write command to write the configuration file into the flash file system,
when the system resets next time, the reserved configuration information will be
configured again.
¾ Use erase command to delete that file
¾ The reserved configuration information file startup_config.conf can be uploaded
to the server by commands upload and download through the FTP protocol or
TFTP protocol, or downloaded to system to replace the old configuration
information.
¾ Use show startup-config command to show the reserved configuration
information.
¾ Use show running-config command to show the present configuration
information.
¾
4.2.2 Startup file
¾ Same as program file, and the file name must begin with OPCOM3100, present
program file name is: OPCOM3100-040109.Z;
¾ The program file can be uploaded to the server by commands upload and
download through the FTP protocol or TFTP protocol, or downloaded to
system.
¾ Use show version to check the version information.

9 Networking
OPCOM3100 is available for low order cross connect of VC-12.
With bi-directional optical interfaces and tributary interfaces of Ethernet and E1,
OPCOM3100 can be configured conveniently to satisfy all the topologies of user access
networks showing as follows:
Topologies
9.1 Point to point topology
Network of point to point topology is available for LAN relay and extending or replace the
old PDH. The networking is as follows:
Topology
TM device can configure point to point none-protection network, and double TMs can
configure the linear low order VC protection of STM-1 level. When configured as 1+1
protection mode, the two optical interfaces can protect each other to enhance service
reliability.
9.2 Chain topology
Network of chain topology is available for the service flow distributed in chain form and
tributary networks in chain form. Network with OPCOM3100 is as follows:
Raisecom Technology Co., Ltd
21
Chain topology
TM and ADM can configure none-protection chain topology network, and double TMs
and ADM can configure the linear low order VC protection of STM-1 level.
When configured as 1+1 protection mode, service reliability will enhance but access
ability will reduce; and when configured as none-protection mode, access ability will
enhance but service reliability will reduce.
9.3 Ring topology
Network of ring topology is available for distribution of network elements in ring form.
With the feather of line interfaces self closed, service can be transmitted bi-directionally
(east and west), so the network has high reliability and self-healing ability. Showing as
follows:
Ring topology
This topology can establish 2F SNC-P.
2F SNC-P
The advantages of 2F SNC-P are high speed, flexibility and all level capacities. The
switching depends on local environment and has nothing to do with the network topology,
so 2F SNC-P is suitable for all kinds’ topologies, especially dynamic network.
The disadvantage of 2F SNC-P is that all the tributaries in the ring are all APS
architectures, that is between any two points, there are two transmission lines
Raisecom Technology Co., Ltd
22
transmitting the data bi-directionally, and every receiving note receives the data
bi-directionally. So the total service flow is lower than the device capacity.
2F SNC-P is suitable for access network, relay network and long distance network.,
which are concentrated, low service flow.

Network topology:
If the network is not only organized by OPCOM3100, DCC channel is not continuous
when there are other types of device or network, in this case we use data network to
manage and control remote OPCOM3100.
