INFORMATION
Overview
The 4 E1 to ethernet converter is the IP ethernet over TDM
converter, which supports the conversion from MAC frames to 1 – 4 E1 lines.
The maximum bit rate is 7.8Mbps (4E1 lines). The 4E1 converter not only provides
alarms and status of the E1 line but also Ethernet interface together with advanced
management functions, such as, throughput statistic of the Ethernet, but also supports the Unification Network Management via
SNMP and GUI .
Compliant to
international standards, the device can communicate with products from other
manufacturers adopting the same standards.

Features
n E1 interface
Ø Supports automatic
removal and recovery of E1 channels that used for carrying payload. The E1
channels that have urgent alarm, such as LOS and LOF, or the Bit Error Rate
(BER) exceeds 1E-6, are removed automatically, and during this period, some
Ethernet packets may be lost; It will be resumed when the fault dismisses .
Ø Supports the embedded
E1 BER Tester function, to detect any E1 channel of 4 channels. When the
embedded E1 BER Tester is used via CLI command, the particular E1 channel on
testing mode can not convey E1 service, while the other E1 channels are not
affected by the BER test.
Ø The differential
delay between any two of the 4 E1 can be up to 220ms; when the factual
differential delay exceeds 220ms, alarm is generated and Ethernet is cut off.
Ø Jitter tolerance and
jitter transfer characteristic compliant to ITU-T G.823.
n Ethernet interface
Ø Provides up to 4
shared Ethernet interfaces.
Ø 1024 MAC address
table and 5-minute aging time.
Ø Accepts frames with
length between 64 and 1916 bytes (otherwise filtering).
Ø VLAN function based
on tags compliant to IEE 802.1Q.
Ø Throughout statistic
of the Ethernet packets based on port, such as error packets.
Ø Configurable pause
flow control .
Ø Optional optical
Ethernet interface compliant to IEEE 802.3u 100BASE-FX standard (can
communicate with remote optical transceiver) and electrical Ethernet interface
compliant to IEEE 802.3u 100 BASE-TX standard.
n Management interface
Ø GUI via serial RS232
port and telnet.
Ø network
management platform based on SNMP(optional).
n Timing mode
Ø Optional local timing
mode and tracing E1 line (set by GUI).
Ø The source of tracing
E1 line can be switched according to the signal quality. For instance, the
system is set as tracing the first E1 link, when some malfunction occurs to it
(i.e., urgent alarm LOS/AIS/LOF/LOMF or the signal is looped back), the system
will automatically change to tracing the second E1 link; when the fault
disappear, the system will be re-tracing the first E1 link.
n Compliant to ITU-T standards
Ø GFP-F encapsulation
recommendation G.7041.
Ø Virtual
concatenation(VCAT) and Link Capacity Adjustment Scheme (LCAS) recommendation
G.7042.
Ø Ethernet to nxE1
mapping recommendation G.7043.
Ø Ethernet to single E1
mapping recommendation G.8040.
n Bandwidth is
increased without damaging the Ethernet data, and can be decreased no injury
through management.
n The E1s in the local
and remote sides can be arranged arbitrarily, such as, the remote E1 port 1 can
communicate with local E1 port 3.
n Supports bandwidth
unbalanced usage – when some E1s cannot work properly (i.e. the bandwidth of
the sending and receiving can be 2E1 and 3E1 respectively ).
n Provides the E1
connection-ship between local and remote system (accessed via GUI).
n E1 tributary signal
loopback automatic detect and cut off; when some E1 signal is detected as
looped back, it will be not employed for carrying payload temporarily, and when
the loopback is broken, this E1 will resume to be used.
n Remote/local E1
loopback function will be convenient for E1 line(transmission system included)
testing .
n Complete alarm which
is selectable to be shown between local and remote.
n support
AC 220V power or DC 48V power or double AC+DC power
n Single-board design
with small dimension, 1 U high and low power consumption.

FAQ about the 4E1 to ethernet converter
Question1: Is the 4E1 converter device capable of deliver the bandwidth of 3 E1s (that is 6Mbps aprox.) to a single Ethetnet port?
Answer: Yes,the 4 E1 to ethernet converter can support total about 8M bandwidth,user can choose 3channel E1 working which transmitting 6Mbps aprox. The four ethernet port can share the total bandwidth,user also can make the total bandwidth transmission by one thernet port.
Qustion2:Can we handle the SNMP Management with
another (different, on the same unit) physical ethertnet port than the used to
move ethernet traffic?
Answer: You can monitor or configure the remote device by RS232 port (GUI management) or
by ETH port (SNMP management).
Qustion3: Can the E1 to Ethernet Converter Power Supply be Changed to DC power?
Answer: If you order the E1 to ethernet converter with one power supply (AC or DC), you can buy the power module from us and change the E1 converter device with another model power supply, details as the below link:
