Riepilogo

The ISDN board SX2 SinglePRI needs to be configured before first use. This article gives an overview about the possible configurations.


Informazioni

Before the SX2 SinglePRI card is installed into the machine you have to configure the RJ-45 socket pinout and the line termination.

The following description assumes you have the card in front of you with the RJ-45 sockets on the left side and the PCI connector pointing in your direction. Each RJ-45 socket has two jumper blocks assigned. Throughout this description the jumper block containing 2 jumpers is named JB2 and that one containing 5 jumpers is named JB5. A suffix L or R means that either all jumpers are on the block's left side (L) or on the right side (R), e.g. JB5L means that all jumpers of JB5 are jumpered to the left side.

The RJ-45 socket pinout can be changed with jumper blocks JB2 and JB5. It is possible to choose out of four different pinouts:

 

Jumper Block Assignment RJ-45 Socket Pinout
JB2L and JB5R

Pin1 = TX+

Pin2 = TX-

Pin4 = RX+

Pin5 = RX-

JB2R and JB5R

Pin3 = TX+

Pin6 = TX-

Pin4 = RX+

Pin5 = RX-

JB2L and JB5L

Pin1 = RX+

Pin2 = RX-

Pin4 = TX+

Pin5 = TX-

JB2R and JB5L

Pin3 = RX+

Pin6 = RX-

Pin4 = TX+

Pin5 = TX-

On the right side beneath the jumper blocks you'll find a DIP switch with two pins. This switch is used to select the line termination. If both pins are "OFF" then no termination is present. If the left pin is "OFF" and the right pin is "ON" a 120 Ohm termination is active. If the left pin is "ON" and the right pin is "OFF" a 75 Ohm termination is active.

The board number can be set with the four DIP switches (blue) located at the upper middle side of the board. The following assignment is valid:

 

Switch 1 Switch 2 Switch 3 Switch 4 board number
off off off on 1
off off on off 2
off off on on 3
off on off off 4
off on off on 5
off on on off 6
off on on on 7
on off off off 8

on off on off 10
on off on on 11
on on off off 12
on on off on 13
on on on off 14
on on on on 15
off off off off automatic

Please make sure that you either assign a board number for all boards in the system or configure all boards for automatic number assignment.

The board provides two connectors with 20 pins each. Those connectors are used to connect two boards with an optional PCM cable. The upper connector is the output and the lower connector is the input. Connect two boards with a PCM cable by connecting the output of the first board with the input of the second board.


LED Status Monitoring

Each E1 socket has assigned four monochrome LEDs as a status monitoring facility.

The following assignment is valid:

 

LED1 off: Layer 1 de-activated
LED1 red: Layer 1 activated
LED2 green: Layer 2 activated
LED3 green blinking: At least one connection active
LED4 red blinking: The line is being configured
