It is used in the telecommunication centres for branching of E1 digital stream without entering of hindrances and breaches of other parametres into the flow;


Continuous round-the-clock work indoors at temperature from 5 ° to 40 ° C and relative humidity of 80 % at temperature 25 ° C (in accordance with 15150 State Standard Specification). The complex satisfies the technical specification TS U 32.2-31633037-002-2002 and can be used in combination with AMUR-PCI-E1-3 digital recorder (the power comes through those lines which are used for information transferring). The device is mounted or placed into the stands or cabinets and other equipment that allows placing this device. AMUR-PVP-E1 is specially developed in such a way that in any situations there will not be any distortions in the connected channel.




Quantity of branching channels:

1 or 2 channels (2-4 directions) (2-4 направления) 

The device is connected to symmetrical physical lines with wave resistance 120 Om and provides branching of the E1 flow channels in accordance with G.703 guidelines.

The guaranteed work of the device is provided when the length of the cable is in the 5-th category for connecting the supply to the device.


from 10 m to 300 m

Change of the output signal duration in comparison with input signal at the half of amplitude level does not exceed


 ±12 nс

The ratio of amplitudes of the positive and negative impulses of the output signal in the central part of impulses in the range of


from 0,95 to 1,05

The ratio of duration of the positive and negative impulses of the output signal in the central part of impulses in the range of


 from 0,95 to 1,05

The device proofs to work in modes without power supply and in modes of the output short circuit, and after elimination of these modes there is no changes in the parametres of the device


Device connection in the tap point of E1 flow does not result in
Increasing of the bit error rate in the mainstream flow up to value not more than 10-9

Changing of the impulses amplitude of the main signal

 at ±10%
Changing of the impulses duration of the main signal at ±5%

The specified characteristics are provided both at the power supply and without power supply.


Power supply of the device can be carried out both distantly (for example: from AMURPCI-E1-3 device) and through the external block of power supply

 The device keeps operating capacity at the supply voltage from 17 V to 28 ВV

Consumed current at the supply voltage 24 V

not more than 3,5 Вт

Connected power supply polarity


In case of the sockets site fault the device does not fail and when the correct connection is restored, the working capacity of the device restores.
