how to configure Hipath4000 V.4 to connect topgate multiplexer

Hi all
We faced problem want to connect two hipath4000V.4 using topgate eltex multiplexers can't get e1 up

RE: how to configure Hipath4000 V.4 to connect topgate multiplexer

Try and get an E1 tester.
Test in to and out of each HiPath

RE: how to configure Hipath4000 V.4 to connect topgate multiplexer

Check both are set to the correct protocol e.g. QSIG, Q.931, DPNSS.
Check that one is set to the A end and one B end.
Check that you have a stable clock source (DIS-REFTA:;). Normally you would use one from an external line.

RE: how to configure Hipath4000 V.4 to connect topgate multiplexer

Did you activate the B-channels (ACT-BSSU/DSSU)?
Check HISTA for L2 Error messages (e.g. F5413).

RE: how to configure Hipath4000 V.4 to connect topgate multiplexer

If Possible - bring one HiPath next to the other and connect them 'back to back' without any carrier in between.
Get them to work correctly that way and if so then there can be little wrong when you introduce the carrier in between.

are:

Port 0 Connector Label : Line 1
Rx Tip ----- Pin 8
Rx Ring --- Pin 15
Xmit Tip --- Pin 1
Xmit Ring - Pin 9

Port 1 Connector Label : Line 2
Rx Tip ------ Pin 8
Rx Ring ---- Pin 15
Xmit Tip --- Pin 1
Xmit Ring - Pin 9


When using a DB15 to RJ45 adapter, connect the pin as follows:
DB15 Pin 8 --- Rx Tip --- RJ45 Pin 1
DB15 Pin 15 -- Rx Ring --- RJ45 Pin 2
DB15 Pin 1 --- Xmit Tip -- RJ45 Pin 4
DB15 Pin 9 --- Xmit Ring - RJ45 Pin 5
