l
Framing
: By default, CPE and NET use CSS (Common Channel Signaling).
l
Coding
: By defaultHDB3.
l
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.
l
Dial Plan
: The ISDN-level Type Of Number (TON) or numbering plan, used for the dialed number. For most
installations, leaving this as 'unknown' (the default) works in the most cases. In some very unusual
circumstances, you may need to set this to 'dynamic' or 'redundant'. Note that if you set one of the others,
you will be unable to dial another class of numbers. For example, if you set 'national', you will be unable to
dial local or international numbers.
l
Local Dial Plan
: Only RARELY used for PRI (sets the calling number's numbering plan). In North America, the
typical use is sending the 10 digit caller ID number and setting the prilocal dial plan to 'national' (the default).
Only VERY rarely will you need to change this.
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 T600 chapter in the LED
Indication section.
If in the deployment you got some 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 ZYCOO, please contact ZYCOO
Support
for help.
