Module Settings
Module Settings are only for configuring digital module cards (El/T1, BRI) on IPX-2200 and IPX-2500
IPPBX systems. Ignore this part if you are using FXS/FXO/GSM/WCDMA modules.
Path: Telephony -> Preferences -> Module Settings
IPX-2200 and IPX-2500 IPPBX systems need proper module settings to load correct drivers and configure files to
drive the E1 and BRI telephony modules.
Default module settings are with module types FXS/FXO/GSM/WCDMA on both telephony module slots. So if you
don’t have E1 and BRI modules installed then you don’t have to configure module settings.
E1 PRI Signaling
E1 module can be installed on both Slot 1 and Slot 2. To ensure IPX-2200/IPX-2500 IPPBX can detect and drive E1
module in the Module Type field, you should choose “E1/T1”.
 Mode: Sets the module to work as E1 mode.
 Signaling: Sets the module to work with PRI CPE or NET, CPE is used on the client side, NET is used on the
telephony provider side.
 Framing: By default CPE and NET use CSS (Common Channel Signaling).
 Coding: By default HDB3.
 CRC4: A method of checking for errors in transmitted data on E-1 trunk lines. Enable it only if the telephony
provider implemented CRC4 on their E1 lines.
These configuration parameters should be given by the telephony provider, please configure these parameters
correctly according to what they give to match the switching equipment being used by the telephony provider.
Once the configurations had been done, save and reboot the IPPBX system. In the meantime you attach the E1
line to the E1 interface. After rebooting you should get LED indications with L1 red, L2 red, L3 off and L4 green of a
successful PRI CPE connection. For more details of the LED indications please check PLANET IPX-2200 and
IPX-2500 chapter in the LED Indication section.
If in the deployment you got someone else connection status you should check with the telephony provider to
confirm the configuration parameters. Or check with them if the line had been activated by them and ready for
phone calls. If you need any help from PLANET, please contact PLANET Support for help.
