Description

Even if the icE1usb support CRC4 enabled or disabled the osmo-e1d process need CRC4 on Rx to align.

I suggest that we do CRC4 check configurable.

On a Cisco modem pool you can disable CRC4 in the E1 controller section:

controller E1 2/1
 framing NO-CRC4
 pri-group timeslots 1-31
 description Towards Kanin-Q921_4

Maybe we can do the same in the line section in the config file, something like this:

e1d
 interface 0 icE1usb
  usb-serial xxxxxxxxxxxx
  line 0
   framing no-crc4
   mode e1oip

  • Category changed from firmware to gateware

The gateware currently has no such support CRC4 is always used for multi frame alignement, so it needs to be added there first.
