2.3 General Rules
Before making any connections to the bridge, please note the following rules:
•Ethernet Port (RJ-45)
All network connections to the bridge Ethernet port must be made using Category 5 UTP or above for
100Mbps, Category 3, 4 UTP for 10Mbps.
No more than 100 meters of cabling may be use between the MUX or HUB and an end node.
•VDSL2 Port (RJ-11)
All network connections to the RJ-11port must use 24~26 gauge with twisted pair phone wiring.
We do not recommend the use of the telephone line 28 gauge or above.
2.4 Connecting the Bridge
The bridge has two Ethernet ports which support connection to Ethernet operation. The devices attached to these
ports must support auto-negotiation or 10Base-T or 100Base-TX unless they will always operate at half duplex. Use
any of the Ethernet ports to connect to devices such as Monitor system, Server, Switch, bridge or router.
Notes:
1. The RJ11 Line port is used to connect to telephone that is connected to VDSL CO and CPE bridge (Point-to-point
solution).
2. Slave device(CPE) must connect Master device(CO) through the telephone wire. Slave cannot connect to Slave,
and Master cannot connect to Master. Please confirm the DIP switch status before the link is established.

PIN1:
ON: CO(Central Office) Mode or called Local Side, usually the CO device will be located at the data enter of enterprise to link to the
backbone.
OFF: CPE(Customer Premises Equipment) Mode or called Remote Side, usually the CPE side will be located at building,
monitoring for car parks and train station as the long reach data receiver.
Tip:
When the ALL-MC115VDLS2 operates at CPE mode, the DIP switch 2, 3, 4 has no function.
PIN2:
ON: High Band mode(500KHz to 30MHz), and enable VDSL2 spectrum is 500kHz to 30MHz. It can pass through ISDN spectrum(0 ~
499KHz are empty).
OFF: Low Band Mode(25KHz to 30MHz), the ALL-MC115VDLS2 will auto-detect the cable length and auto choice speed mode.
VDSL2 spectrum is 25KHz to 30MHz.
PIN3:
When SNR margin is selected, the system provide 6db/9db SNR margin for across all usable loop length. Please note that the 6db
SNR margin is for telecom standard. Generally speaking, the higher SNR value gets better line quality, but lower performance.
PIN4:
ON: Interleaved mode has a maximum end to end latency of 8m sec and INP=2. When field environment has heavy noise, in order
to obtain high link quality, user can config pin4 to “ON”, but this function will reduce performance.
OFF: Interleaved mode provides impulse noise protection for any impulse noise with a duration less than 1ms.

ALL-MC115VDSL2 Mini Modem Master/Slave Manual

TIP(Reference Only):
Interleave delay function is used in digital data transmission technology to protect the transmission against noise issue
and data error.
If during transit more than a certain amount of data has been lost then the data cannot be correctly decoded. Short bursts
of noise on the line can cause these data packets to become corrupt and the bridge has to re-request data which in turn
can slow down the overall rate at which data is transmitted.
Interleaving is a method of taking data packets, chopping them up into smaller bits and then rearranging them so that
once contiguous data is now spaced further apart into a non continuous stream. Data packets are re-assembled by your
bridge.
The diagram below is an example of how interleaved traffic is transmitted.
If your line is particularly susceptible to bursts of noise then interleaving should improve your VDSL2 experience simply
because if you lose a whole batch of data then this could cause your bridge to loose sync with the exchange.
Using Interleaving, the bridge is able to re-assemble the data or if necessary just re-request the part of the data that it is
unable to recover. By increasing the interleave depth of each ports that are susceptible to noise, this will improve error
performance and stability of marginal lines.

INP(Impulse Noise Protection): Impulse noise in multicarrier communication systems behaves effectively as a modulating
signal that controls the first moment of the background Gaussian noise. The composite noise, which is the aggregate of the
Gaussian noise and impulse noise, has a probability density function that is conditionally Gaussian with non-zero average,
hence referred to as biased-Gaussian. The BER-equivalent power of the composite noise source is defined as the power of a
pure Gaussian noise source that yields the same bit-error rate (BER). The BER-equivalent noise for a biased-Gaussian noise
is simply the amplified version of the underlying Gaussian noise source. The amplification factor is derived from the
characteristics of the impulse interference. Any bit-loading algorithm designed for Gaussian noise sources is also applicable to
biased-Gaussian noise sources provided that the BER-equivalent SNR is used in place of the measured SNR.
SNRM(Signal to Noise Ratio Margin): It's very similar to a conversation at a party and it's dealt with in the same way; we naturally
account for both distance from the other person and the amount of background noise. When we do we don't just talk loud enough to
be heard, we speak a bit louder waiting for the idiot with the stupid, loud laugh to start up again. We add a bit extra on to make sure
we're louder than the average change in background noise.
That ratio is a major factor in determining the connection speed, as the higher the ratio the higher the possible speed. The SNRM is a
margin which by which the noise level can rise before connection is lost.
Safety Caution!
1. Be sure to disconnect the power when installing(uninstalling) the terminal block and power cable.
2. Please note that the user can use 12VDC power input. Do not exceed DC 12V.
3. Be sure to disconnect the power before installing and/or wiring your ALL-MC115VDLS2 bridge.
4. Please calculate the maximum possible current in each power wire and common wire. Observe all electrical codes
dictating the maximum current allowable for each wire size. If the current goes above the maximum ratings, the wiring
could overheat, causing serious damage to your equipment.

Grounding the ALL-MC115VDLS2
ALL-MC115VDLS2 is designed to enhance EMS performance by grounding. ALL-MC115VDLS2 come with for grounding the
switches. For optimal EMS performance, connection of the left side of the ALL-MC115VDLS2 rear panel ground lug to the grounding
point.
Before user installed power and device, please read and follow these essentials:
 Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must cross, make sure the
wires are perpendicular at the intersection point.
Note:
Do not run signal or communications wiring and power wiring through the same wire conduit. To avoid interference, wires with
different signal characteristics should be routed separately.
 You can use the type of signal transmitted through a wire to determine which wires should be kept separate. The rule of thumb
is that wiring sharing similar electrical characteristics can be bundled together.
 You should separate input wiring from output wiring.
 We recommend that you mark all equipment in the wiring system.
